Lactobacilli administration has been suggested for the treatment and prevention of bacterial vaginosis, which increases the risk for preterm birth. We aimed to evaluate the vaginal colonization of lactobacilli orally administered to pregnant women at risk for preterm birth. We performed a randomized and controlled crossover study between January 2016 and May 2017. Forty pregnant women at high risk for preterm birth with normal vaginal flora (Nugent score ≤ 3) were randomized to either receive two oral capsules/day each containing 5 × 109 Lactobacilli (L.) rhamnosus GR-1 and L. reuteri RC-14 (n = 20) or no treatment (n = 20) for 2 months. Treatments were then crossed over for an additional two months. A vaginal examination and swabbing were performed for assessment of bacterial vaginosis at baseline and every month until study completion. At the same time points, vaginal samples were cultured and subjected to matrix-assisted-laser-desorption/ionization-time-of-flight-mass-spectrometry (MALDI TOF-MS) for the detection of the specific bacterial strains contained in the capsules. The primary endpoint was the presence of the administered lactobacilli strains in the vagina during the first two months of follow-up. Thirty-eight women completed the study. During the first two months of treatment, L. rhamnosus GR-1 was detected in one (5%) woman on the probiotic treatment and 2 (11%) women receiving no treatment (p = 0.6). L. rhamnosus GR-1 was detected in vaginal samples of 4 (11%) women during probiotic treatment (of both groups) and L. reuteri RC-14 was not detected in any samples. The rest of the endpoints were not different between the groups. Altogether, vaginal colonization of lactobacilli following oral administration is low during pregnancy.

Abstract Objective To determine reference values for myocardial volume of the fetal heart using three-dimensional ultrasound with spatiotemporal image correlation (STIC) and virtual organ computer-aided analysis (VOCAL) and to assess their applicability in women with pregestational diabetes. Study Design This retrospective cross-sectional study included 177 normal pregnant women with fetuses between 200/7 and 336/7 weeks of age. Fetal cardiac volumes were collected using the STIC method, and myocardial volume was obtained by subtraction of the intracavitary volumes using the VOCAL 30-degree method. Intra- and interobserver reproducibility values were determined using the concordance correlation coefficient (CCC). Sixteen women with pregestational diabetes mellitus were evaluated for validation. Results There was a strong correlation between fetal myocardial volume and gestational age (R 2 = 0.82). Intra- and interobserver reproducibility values were excellent and moderate, respectively, with CCCs of 0.99 and 0.83, respectively. There was no significant difference in mean fetal myocardial volume between normal pregnant women and those with pregestational diabetes (p = 0.64). Conclusion Reference values for myocardial volume of the fetal heart were determined in normal pregnant women and were not statistically different from those in women with pregestational diabetes mellitus.
