Health of Infants After ART-Treated, Subfertile, and Fertile Deliveries.

ABSTRACT: OBJECTIVES:To assess the risk of adverse health outcomes for infants after assisted reproductive technology (ART)-treated and subfertile as compared with fertile deliveries. METHODS:Live-born singleton infants ?23 weeks' gestational age (GA) born in Massachusetts between July 1, 2004, and December 31, 2010, were analyzed by linking a clinical ART database with state vital records. ?2 tests were used to compare the outcomes of fertile (those without ART treatment or other indicators of infertility), subfertile (indicators of infertility, no ART), and ART-treated (linked to ART deliveries) mothers, stratified by GA. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated by using multivariate logistic regression within each GA stratum, controlling for maternal sociodemographic and health characteristics. RESULTS:Compared with infants of fertile mothers (n = 336?705), infants born to subfertile (n = 5043) or ART-treated (n = 8375) mothers were more likely to be preterm (aOR 1.39 [95% CI 1.26-1.54] and aOR 1.72 [95% CI 1.60-1.85], respectively) and have respiratory and gastrointestinal and/or nutritional conditions (aOR range: 1.12-1.18). When stratified by GA, infants of subfertile or ART-treated mothers were at greater risk for congenital malformations and infectious diseases as well as cardiovascular and respiratory conditions (aOR range: 1.30-2.61; 95% CI range: 1.02-4.59). Compared with infants born to subfertile mothers, infants born to ART-treated mothers were at lower risk for being small for GA and having congenital malformations and cardiovascular conditions and at higher risk for infectious disease conditions. CONCLUSIONS:Compared with infants born to fertile mothers, infants of subfertile and ART-treated mothers are at greater risk for adverse health outcomes at birth beyond prematurity. The occurrence and magnitude of these risks vary by GA and organ systems.

Project description:The miRNA profiles were measured using small-RNA sequencing in beef heifers sampled at weaning that was retrospectively classified as fertile or subfertile following the breeding protocol. To accomplish this, the miRNA profiles were generated from the blood samples (10 mL) collected from crossbred heifers (Angus-Simmental) at the time of weaning (~238 days after birth). Peripheral white blood cells (PWBC) were extracted from the blood samples and stored at -80°C until further processing. During the breeding season, all the heifers followed the same breeding protocol, estrus synchronization, and fixed-time artificial insemination (AI). Fourteen days following the fixed-time AI, the non-pregnant heifers were exposed to fertile bulls for 60 days. Depending on the presence or absence of conceptus at 75 days following AI, heifers were classified as fertile for those who were pregnant through artificial insemination, pregnant to natural breeding (P-NB), or subfertile for those who were not pregnant. Heifers from fertile (n = 7) and subfertile (n = 7) groups were considered for the study. Total RNA was extracted from the PWBC of 14 samples and was subjected to small RNA library preparation and sequencing. After quality control, adapter trimming, and alignment, mature miRNAs were used for differential expression analysis. The read counts were transformed to counts per million (CPM), and raw counts with CPM < 1 in 50% of the samples were filtered out. The filtered raw counts were analyzed using DESeq2 v 1.26.0 to identify differentially expressed miRNAs (DEMIs). The DEMIs identified with a p-value < 0.05 and absolute (log2 fold change) > 0.5 were considered significant. With the subfertile heifers as the reference group, we identified 16 DEMIs between fertile and subfertile groups. To determine the genes targeting the DEMIs, we downloaded the target genes for each DEMI and retained only those genes expressed in the PWBCs. For the miRNA-gene correlation, we used the partial correlation and information theory (PCIT) approach to identify the significant gene-miRNA correlated pairs. The significant genes correlated with the miRNAs identified pathways including MAPK, ErbB, HIF-1, FoxO, p53, mTOR, T-cell receptor, insulin and GnRH signaling, apoptosis, and pathways regulating pluripotency of stem cells in the fertile group while cell cycle, p53 signaling pathway and apoptosis pathways in the subfertile group.

Project description:The gene expression profiles were measured using RNA-Seq beef heifers sampled at weaning and retrospectively classified as pregnant through artificial insemination (AI-P, n = 8) or non-pregnant (NP, n = 7). In brief, crossbred heifers (Angus-Simmental) were used in this study. At the time of weaning (~238 days after birth), blood samples (10 mL) were collected from the jugular vein into vacutainers containing EDTA. The blood was processed to extract PWBC and was stored at -80 until further processing. During the breeding season, all the heifers followed the same breeding protocol, estrus synchronization, and fixed-time artificial insemination (AI). Fourteen days following the fixed-time AI, the non-pregnant heifers were exposed to fertile bulls for 60 days. Depending on the presence or absence of conceptus at 75 days following AI, heifers were classified as pregnant to AI (AI-P), pregnant to natural breeding (P-NB) or non-pregnant (NP). Heifers that were pregnant to AI (N = 8) and non-pregnant (N = 7) were considered for the study. Total RNA was extracted from peripheral white blood cells of 15 samples (AI-P and NP) and was subjected to sequencing. The RNA-Seq data were subjected to quality control and mapped with STAR aligner to Ensemble’s ARS UCD1.2 Bos taurus reference genome. Read quantification was performed using a STAR aligner to obtain raw counts per gene. Genes with low counts were filtered out. After filtering, the read counts were analyzed using DESeq2 v 1.26.0 to identify differentially expressed genes (DEGs). The DEGs with padj < 0.05 and absolute (log2 fold change) > 0.5 were considered significant. The NP heifers were considered as the reference group, and the DEGs up or downregulated were classified based on the log2 fold change direction. We identified 92 DEGs between AI-P and NP groups. The top pathways identified with DEGs were the immune system, cytokine production and defense response, hematopoietic cell lineage, positive regulation of reactive oxygen species metabolic process, and negative regulation of cysteine-type endopeptidase activity involved in the apoptotic process.
