AI Article Synopsis
- The study explored metabolomic differences in amniotic fluid (AF) between women delivering at term and those delivering preterm during the second trimester.
- Using near-infrared spectral analysis, researchers developed a classification model that accurately identified term and preterm births with 100% sensitivity and specificity.
- Results indicated significant differences in metabolomic profiles related to proteins, carbohydrates, fats, and other components, revealing a clear distinction between the two groups.
Article Abstract
This pilot study investigated the possibility that metabolomic differences exist in second trimester of women delivering at term (≥37 weeks, n = 216) and preterm (≤35 weeks, n = 11). For this retrospective study, biobanked AF samples underwent near-infrared (NIR) spectral analysis using wavelengths from 700 to 1050 nm. Spectral data was compressed then optimized by multilinear regression to create a calibration model. The resultant model was able to classify term and preterm births based on differing AF metabolomic profiles with a sensitivity and specificity of 100%. When groups were classified using a prematurity index (PI), there was a statistical difference (P < 0.001) between the predicted preterm group (PI 0.77 ± 0.08) and the term group (PI 1.00 ± 0.02). In conclusion, the 2nd trimester AF samples showed distinct differences in metabolomic profiles between patients delivering preterm as compared to those at term in functional groups related to proteins, carbohydrates, fats, polyols, and water.

Noninvasive prenatal diagnosis (NIPD) of non-syndromic hearing loss (NSHL) for singleton and twin pregnancies in the first trimester.

Background: Noninvasive prenatal diagnosis (NIPD) has been proven feasible for non-syndromic hearing loss (NSHL) in singleton pregnancies. However, previous research is limited to the second trimester and the application in twin pregnancies is blank. Here we provide a novel algorithmic approach to assess singleton and twin pregnancies in the first trimester.

The benefits and risks of delivery should always be considered before initiating preinduction cervical ripening and labor induction. Understanding the benefits and potential complications is crucial for healthcare professionals to make informed decisions and provide optimal care. The research was conducted retrospectively between January 2019 and July 2022.

Purpose: To quantify the separation between maternal blood cell-free (cf)DNA markers in preeclampsia and unaffected pregnancies and compare with existing markers. This approach has not been used in previous studies.
Methods: Comprehensive systematic literature search of PubMed to identify studies measuring total cfDNA, fetal cf(f)DNA or the fetal fraction (FF) in pregnant women.
Sequestration of parasites in the placental vasculature causes increased morbidity and mortality in pregnant compared to non-pregnant patients in malaria- endemic regions. In this study, outbred pregnant CD1 mice with semi allogeneic fetuses were infected with transgenic or mock-inoculated by mosquito bite at either embryonic day (E) 6 (first trimester-equivalent) or 10 (second trimester- equivalent) and compared with non-pregnant females. -infected mosquitoes had greater biting avidity for E10 dams than uninfected mosquitoes, which was not apparent for E6 dams nor non-pregnant females.

This case report describes the difficulty in predicting the outcomes for a fetus affected with both left-sided congenital diaphragmatic hernia and second-trimester pre-viable rupture of membranes. Despite the reserved prognosis at the time of diagnosis, a favourable outcome was obtained. The case highlights the relevance of established prognosticators such as the observed/expected lung/head ratio and also underscores the importance of balanced counselling and providing parents with realistic expectations and appropriate support.
