Twenty 740 Y-P's Which Will Rock n roll This Halloween Season

We used Cox proportional hazards regression models, with gestational weeks as the time scale, to compute hazard ratios (HRs) of SAB and 95% confidence intervals (CIs). After adjustment for potential confounders, the HRs for SAB among underweight (body mass index (BMI, kg/m2) gamma aminobutyric acid function normal weight women (BMI 20�C24). The association between obesity and SAB was stronger for early SAB (740 Y-P cost association between obesity and SAB risk. Our results suggest that obesity is a stronger risk factor for early pregnancy losses, and that small stature and low WHR are associated with an increased risk of SAB. ""Our goal is to study the triggers of spontaneous preterm delivery using a case-crossover design. In a pilot study, we enrolled 50 women with spontaneous preterm labour (PTL) and 50 with preterm premature rupture of membranes (PPROM) between 2011 and 2012. To assess non-transient risk factors, we also enrolled a control group of 158 pregnant women at their regular prenatal care visits matched to cases by gestational age and calendar time. The index time was defined as the onset of PTL/PPROM (for cases) or interview (for controls). Detailed data were collected through structured interviews regarding factors of interest during the 72?h that preceded the index time. Within ALG1 case subjects, we compared the frequency of transient factors from 0 to 24?h before index time with that from 48 to 72?h before index time, and estimated matched odds ratios (OR) and 95% confidence intervals (CI). Previously hypothesised chronic risk factors for spontaneous preterm delivery, including mood disorders and stressful events, were more common among cases than among controls. Within cases, skipped meals [OR 4.3, 95% CI 1.2, 15.2], disturbed sleep [OR 4.5, 95% CI 1.5, 13.3], sexual activity [OR 6.0, 95% CI 0.7, 69.8], and intake of spicy foods [OR 7.0, 95% CI 1.6, 30.8] were associated with an increased risk for PTL/PPROM within the subsequent 24?h. For physical exertion and other potential risk factors evaluated, the OR was close to the null. Skipping meals and disturbed sleep may be associated with imminent PTL/PPROM; sexual activity and spicy food may trigger PTL/PPROM in susceptible women. Larger case-crossover studies will be able to evaluate the impact of modifiable risk factors and acute predictors of PTL/PPROM, and might help guide obstetrical management.
