Hospitals and clinics from ten cities across Canada.... A total of 1784 pregnant women.... Concentrations of arsenic, cadmium, lead, manganese and mercury were measured in maternal whole blood during the first trimester of pregnancy as a proxy of preconception exposure. Discrete-time Cox pr... TTP was self-reported as the number of months of unprotected intercourse to become pregnant. Infertility was defined as TTP longer than 12 months.... A total of 1784 women were eligible for the analysis. Mean ± SD maternal age and gestational age at interview were 32.2 ± 5.0 years, and 11.6 ± 1.6 weeks, respectively. Exposure to arsenic, cadmium, m... Blood concentrations of metals at typical levels of exposure among Canadian pregnant women were not associated with TTP or infertility.

Predicting Preeclampsia Pregnancy Termination Time Using sFlt-1.

The aim of this study was to determine the usefulness of placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) in predicting the time for pregnancy termination in pregnant wom... Forty-four pregnant women diagnosed with PE (22 weeks 0 days to 33 weeks 6 days gestation) were included in this study. The levels of sFlt-1 and PlGF, and the sFlt-1/PlGF ratio were compared between t... Among sFlt-1, PlGF, and sFlt-1/PlGF, sFlt-1 was the most significantly associated with the timing of pregnancy termination. sFlt-1 cutoff values of 8682.1 pg/ml (AUC 0.71; 95%Cl, 0.5191-0.9052) and 7,... This study showed that sFlt-1 may be effective in predicting the timing of pregnancy termination. However, the number of cases was small and, thus, the results were not definitive. This finding should...

Compared with the fourth (highest) quartile, corresponding to the most job independence, FRs (95% CI) for fi... Lower job control, a work-related stressor, may adversely influence time-to-pregnancy. As job control is a condition of work (i.e., not modifiable by individuals), findings may strengthen arguments fo...

Chromosomal microarray analysis in pregnancy loss: Is it time for a consensus approach?

To investigate the efficacy and outcomes of chromosomal microarray (CMA) in the cytogenomic evaluation of products of conception (POC).... Over a 42-month period, 323 POC samples were tested by CMA. Results were assessed using variables including phenotype, gestational age, results from orthogonal testing, and follow-up parental analysis...
