Abstract Subclinical hypothyroidism (SCH) in pregnancy has become an important complication of pregnancy. We used nontargeted lipidomics to compare differential metabolites between women with SCH and healthy women. The metabolic pathways of the differential metabolites were analyzed using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. We found: 1. Multivariate analysis revealed 143 lipid molecules with different levels between the SCH group and the control group. Based on fold change, 30 differential lipid metabolites were selected as potential biomarkers. 2. KEGG pathway enrichment analysis showed that the differential metabolites participate in such pathways as pathogenic Escherichia coli infection response, metabolic pathways, glycerophospholipid metabolism. 3. Correlation analysis showed that sphingomyelin (SM) and phosphatidylcholine (PC) were positively correlated with tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and interleukin-6 (IL-6), while phosphatidylglycerol (PG), and phosphatidylinositol (PI) were negatively correlated with them. And PG was positively correlated with birth weight. The lipid profile of pregnant women with SCH is significantly different from that of healthy pregnant women. Lipid molecules with differential metabolism, such as SM, PE, and PI, might be targets for further investigation of the pathogenesis of SCH in pregnancy and reduce the incidence of adverse pregnancy outcomes.

AbstractSubclinical hypothyroidism (SCH) has become a prevalent complication in pregnancy. Recent research links SCH to disturbed thyroid lipid profile; however, it is unclear how lipid metabolism disorders contribute to the pathogenesis of SCH during pregnancy. Thus, we used nontargeted lipidomics to identify and compare the lipids and metabolites expressed by pregnant women with SCH and healthy pregnant women. Multivariate analysis revealed 143 lipid molecules differentially expressed between the SCH group and the control group. Based on fold change, 30 differentially expressed lipid metabolites are potential biomarkers. KEGG pathway enrichment analysis showed that the differentially expressed metabolites participate in several pathways, including response to pathogenic Escherichia coli infection, regulation of lipolysis in adipocytes, metabolic pathways, glycerophospholipid metabolism, and fat digestion and absorption pathways. Correlation analyses revealed sphingomyelin (SM) and phosphatidylcholine (PC) positively correlate to tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and interleukin-6 (IL-6), while phosphatidylglycerol (PG), and phosphatidylinositol (PI) negatively correlate with them. In addition, PG positively correlates to birth weight. Thus, the lipid profile of pregnant women with SCH is significantly different from that of healthy pregnant women. Lipid molecules associated with the differential lipid metabolism, such as SM, phosphatidylethanolamine (PE), and PI, should be further investigated for their roles in the pathogenesis of SCH in pregnancy, as they might be targets for reducing the incidence of adverse pregnancy outcomes.

Abstract Aims: This study was to evaluate the effects of the home quarantine on pregnancy outcomes of gestational diabetes mellitus (GDM) patients during the COVID-19 outbreak.Methods: Thecomplete electronic medical records of GDM patients with home quarantine history were collected and classified into the home quarantine group from 24 February 2020 to 24 November 2020. The same period of GDM patients without home quarantine historywas included in the control group from 2018 and 2019.Results: A total of 1358 GDM patients were included in the analysis, including 484 in 2018, 468 in 2019, and 406 in 2020. GDM patients with home quarantine in 2020 had higher glycemic levels and worse pregnancy outcomes than 2018 and 2019, including higher cesarean section rate,lower Apgar scores, and higher incidence of macrosomia and nuchal cord. More importantly, the second trimester of home quarantine had brought a broader impactto pregnant women and fetuses.Conclusion: Home quarantine has aggravated the condition of GDM pregnant women and brought more adverse pregnancy outcomes during the COVID-19 outbreak. Therefore, we suggested that governments and hospitals should strengthen lifestyle guidance, glucose management, and antenatal care for GDM patients with home quarantine during public health emergencies.

AbstractBackgroundSchistosomiasis is a Neglected Tropical Disease with endemic foci in Cameroon. Epidemiological data on schistosomiasis in pregnancy are scarce in the country. This study is about schistosomiasis among pregnant women in the Njombe-Penja health district, where schistosomiasis was reported since 1969.MethodologyOverall, 282 pregnant women were enrolled upon informed consent at first antenatal consultation. A questionnaire was administered to document socio-economic and obstetric information. Stool and terminal urine samples were collected and analysed using the Kato-Katz/formol-ether concentration techniques and centrifugation method respectively. Haemoglobin concentration was measured with finger prick blood, using a URIT-12® electronic haemoglobinometer.Principal findingsThe overall prevalence of schistosomiasis was 31.91%. Schistosoma guineensis, S. haematobium and S. mansoni infections were found in 0.35%, 04.96% and 28.01% of participants respectively. Co-infection with 2 species of Schistosoma was found in 04.44% of these women. The prevalence of schistosomiasis was significantly higher in younger women (≤20) and among residents of Njombe. All S. haematobium infected women were anemic and infection was associated with significantly lower haemoglobin levels (p=0.02).ConclusionThe prevalence of schistosomiasis is high in pregnant women of the Njombe-Penja health district, with possible adverse pregnancy outcomes. Female of childbearing age should be considered for mass drug administration.Author summaryPregnant women are known to be more vulnerable to infectious diseases and in their case, at least two lives are at risk. Although schistosomiasis remains a major public health issue in Cameroon, epidemiological data on schistosomiasis in pregnancy are scarce. These data are of high interest for informed decision-making. We examined stools and urines from 282 women of the Njombe-Penja Health district and measured their blood levels. Overall, 31.91% of women were infected, mostly younger ones and those living in the town of Njombe. Three species of Schistosoma parasite were identified. Women having urinary schistosomiasis had lower blood levels. These results show that the prevalence of schistosomiasis is high in pregnant women of Njombe. Also, because of the anemia it induces, the disease can lead to adverse pregnancy outcomes on the woman and her foetus. Treating female of childbearing age would cure the disease and prevent adverse outcomes.

AimsOur aim was to evaluate the separate and combined effects of maternal pre-pregnancy obesity and gestational abnormal glucose metabolism (GAGM) on adverse perinatal outcomes.MethodsA total of 2,796 Chinese pregnant women with singleton delivery were studied, including 257 women with pre-pregnancy obesity alone, 604 with GAGM alone, 190 with both two conditions, and 1,745 with neither pre-pregnancy obesity nor GAGM as control group. The prevalence and risks of adverse pregnancy outcomes were compared among the four groups.ResultsCompared with the normal group, pregnant women with maternal pre-pregnancy obesity alone, GAGM alone, and both two conditions faced significantly increased risks of pregnancy-induced hypertension (PIH) (odds ratio (OR) 4.045, [95% confidence interval (CI) 2.286–7.156]; 1.993 [1.171–3.393]; 8.495 [4.982–14.485]), preeclampsia (2.649 [1.224–5.735]; 2.129 [1.128–4.017]; 4.643 [2.217–9.727]), cesarean delivery (1.589 [1.212–2.083]; 1.328 [1.095–1.611]; 2.627 [1.908–3.617]), preterm delivery (1.899 [1.205–2.993]; 1.358 [0.937–1.968]; 2.301 [1.423–3.720]), macrosomia (2.449 [1.517–3.954]; 1.966 [1.356–2.851]; 4.576 [2.895–7.233]), and total adverse maternal outcomes (1.762 [1.331–2.332]; 1.365 [1.122–1.659]; 3.228 [2.272–4.587]) and neonatal outcomes (1.951 [1.361–2.798]; 1.547 [1.170–2.046]; 3.557 [2.471–5.122]). Most importantly, there were no obvious risk differences in adverse pregnancy outcomes between maternal pre-pregnancy obesity and GAGM group except PIH, but pregnant women with both obesity and GAGM exhibited dramatically higher risks of adverse pregnancy outcomes than those with each condition alone.ConclusionsMaternal pre-pregnancy obesity and GAGM were independently associated with increased risks of adverse pregnancy outcomes. The combination of pre-pregnancy obesity and GAGM further worsens adverse pregnancy outcomes compared with each condition alone.

Background The rise in the global prevalence of diabetes, particularly among younger people, has led to an increase in the number of pregnant women with preexisting diabetes, many of whom have diabetes-related microvascular complications. We aimed to estimate the magnitude of the risks of adverse pregnancy outcomes or disease progression in this population. Methods and findings We undertook a systematic review and meta-analysis on maternal and perinatal complications in women with type 1 or 2 diabetic microvascular disease and the risk factors for worsening of microvascular disease in pregnancy using a prospective protocol (PROSPERO CRD42017076647). We searched major databases (January 1990 to July 2021) for relevant cohort studies. Study quality was assessed using the Newcastle–Ottawa Scale. We summarized the findings as odds ratios (ORs) with 95% confidence intervals (CIs) using random effects meta-analysis. We included 56 cohort studies involving 12,819 pregnant women with diabetes; 40 from Europe and 9 from North America. Pregnant women with diabetic nephropathy were at greater risk of preeclampsia (OR 10.76, CI 6.43 to 17.99, p < 0.001), early (<34 weeks) (OR 6.90, 95% CI 3.38 to 14.06, p < 0.001) and any preterm birth (OR 4.48, CI 3.40 to 5.92, p < 0.001), and cesarean section (OR 3.04, CI 1.24 to 7.47, p = 0.015); their babies were at increased risk of perinatal death (OR 2.26, CI 1.07 to 4.75, p = 0.032), congenital abnormality (OR 2.71, CI 1.58 to 4.66, p < 0.001), small for gestational age (OR 16.89, CI 7.07 to 40.37, p < 0.001), and admission to neonatal unit (OR 2.59, CI 1.72 to 3.90, p < 0.001) than those without nephropathy. Diabetic retinopathy was associated with any preterm birth (OR 1.67, CI 1.27 to 2.20, p < 0.001) and preeclampsia (OR 2.20, CI 1.57 to 3.10, p < 0.001) but not other complications. The risks of onset or worsening of retinopathy were increased in women who were nulliparous (OR 1.75, 95% CI 1.28 to 2.40, p < 0.001), smokers (OR 2.31, 95% CI 1.25 to 4.27, p = 0.008), with existing proliferative disease (OR 2.12, 95% CI 1.11 to 4.04, p = 0.022), and longer duration of diabetes (weighted mean difference: 4.51 years, 95% CI 2.26 to 6.76, p < 0.001) than those without the risk factors. The main limitations of this analysis are the heterogeneity of definition of retinopathy and nephropathy and the inclusion of women both with type 1 and type 2 diabetes. Conclusions In pregnant women with diabetes, presence of nephropathy and/or retinopathy appear to further increase the risks of maternal complications.

Adverse Pregnancy

To evaluate whether periconceptional exposure to oral contraceptives (OCs) increased adverse pregnancy outcomes, 136 pregnant women taking OCs within the periconceptional period were identified at the Korean Motherisk Program. Of them, 120 pregnant women accepted to participate in their study and were followed up until completion of the pregnancy. A control group of 240 age- and gravidity-matched pregnant women exposed to non-teratogen drugs for at least 1 month before pregnancy was also included. The median gestational age at delivery was 39.1 (27.0–41.0) weeks in the exposed group and 39.3 (27.4–42.0) weeks in the control group ( P = 0.19). In the exposed group, 7.1% of babies were born with low birth weight versus 2.6% in the control group ( P = 0.068). The number of preterm deliveries or babies born large for gestational age did not differ between the two groups. In the exposed group, the rate of birth defects was 3.2% ( n = 3/99) versus 3.6% ( n = 7/193) in the control group ( P = 1.0). There were 15 women who took high doses of progesterone (emergency contraception) and no adverse fetal outcomes were observed. In conclusion, periconceptional exposure to OCs does not appear to increase the risk for adverse pregnancy outcomes.

Objective There are few published data about possible effects of veinotonics in pregnant women. The present study investigates potential adverse drug reactions of veinotonics in pregnancy. Method EFEMERIS is a database including prescribed and dispensed reimbursed drugs during pregnancy (data from Caisse Primaire d’Assurance Maladie) and outcomes (data from Maternal and Infant Protection Service and Antenatal diagnostic Centre). Women who delivered from 1 July 2004 to December 2007 in Haute-Garonne and were registered in the French Health Insurance Service have been included in the EFEMERIS database. We compared pregnancy outcomes and newborn health between women exposed to veinotonics during pregnancy and unexposed women. Results We found that 8998 women (24%) had received at least one prescription for venotonic agents during their pregnancy, corresponding to the period of organogenesis in 1200 cases. We compared data for these women with those for the 27,963 women for whom these drugs were not prescribed during pregnancy. The most widely used veinotonics were hesperidin, diosmin and troxerutin. Pregnancies led to 98.4% versus 93.6% of live births, 0.2% versus 0.2% of postnatal deaths and 1.6% versus 6.4% of pregnancy termination (miscarriage, ectopic pregnancy, medical termination, intrauterine death) in exposed and non-exposed groups, respectively. The risks of pregnancy termination (HR = 0.71 (0.60–0.84)) and prematurity (HR = 0.82 (0.73–0.93)) remained significantly lower in the women exposed to venotonics than in unexposed women. In the group of newborns whose mother had a prescription of veinotonics during organogenesis, 39 out of 1200 (3.4%) had a malformation versus 789 (3.0%) in the control group (ORa = 1.134 (0.873–1.472)). The risk of neonatal diseases was not increased by exposure to venotonic agents in the third trimester (4.9% versus 6.1% for the controls, ORa = 1.07 (0.95–1.20)). Conclusion We found no increased risk of adverse pregnancy outcome among women exposed to veinotonics compared with unexposed pregnant women.

Bacterial vaginosis and periodontal diseases share very similar pathogenesis. Each of these diseases occurs when healthy microbiome changes to predominately anaerobic bacterial flora. Bacterial vaginosis is proven factor for adverse pregnancy outcomes. In recent years it has been hypothesized that infection from distant sites of the fetoplacental unit may also elicit an inflammatory response in utero. Aim: The study is designed to determine whether the presence of specific oral anaerobic bacteria in subgingival sulcus of mother increase the risk of adverse obstetric outcomes. Material and Methods: Case-control study.  Control group: 50 patients who gave birth to neonate whit normal birth weight at term. Group cases: I group - 40 pregnant women who were hospitalized with signs of preterm labor. II - 20 pregnant women, who have an ultrasound diagnosis of fetal growth retardation. Sub-gingival microbiological paper-point swab was taken in all patients. Results: The total number of isolated oral anaerobic bacteria was statistically significantly higher in the cases group compared to control group p <0.01. In our study, pregnant women who tested positive for Porphyrmonas gingivalis for 6.65 times were more likely to have preterm labor compare with pregnant women with negative oral swabs (95.0% CI: 1.38-32.11 / p <0.05), and for 2,79 times more likely to have fetus with intrauterine growth restriction (95.0% CI: 1.10-7.91 / p <0.05 Conclusions: The study confirmed the hypothesis of a statistically significant association between oral anaerobic infection and adverse pregnancy outcomes. In the future, more studies are needed to investigate the role of the microbial load, maternal immune response, pathophysiological pathway that leads to negative pregnancy outcome.

Abstract Aim: (1) To evaluate the prevalence of inherited thrombophilia in pregnant women with adverse pregnancy outcomes: intrauterine growth retardation (IUGR), preeclampsia (PE) and placental abruption. (2) To assess the impact of inherited thrombophilia on the nature of obstetric complications. (3) To assess levels of protein S, protein C, antithrombin III and homocysteine in pregnant women with adverse pregnancy outcomes. Subjects and methods: The study comprised 162 pregnant women. The patients were divided into three test groups and one control group. In all 162 patients the following tests were completed: activated protein C resistance (APC-R), the level of free protein S, activity of protein C, antithrombin III and the level of homocysteine. The data were statistically analyzed via χ2 of independence or homogeneity test. Results: In 32 of 162 patients participating in clinical research thrombophilia was diagnosed (10 patients with APC-R, 21 patients with protein S deficiency, one patient with hyperhomocysteinemia): seven patients belonged to the control group and 25 patients had diagnosed adverse pregnancy outcomes (P=0.04). In 32 patients with diagnosed thrombophilia, level of protein S was decreased (P=0.04). Protein S deficiency was diagnosed, when level of protein S was lower than 30% in the second trimester and lower than 24% in the third trimester. The incidence of activated protein C resistance caused by the mutation of factor V Leiden was in six patients (5.9%) with adverse pregnancy outcomes, and in four patients (6.6%) from the control group. Results were not statistically significant. No protein C deficiency was diagnosed (diagnosis: level<60%), but in 50% of patients with thrombophilia level of protein C was over the norm (P=0.02). The level of antithrombin III was often decreased in patients with preeclampsia – (32.4%), then in the other patients – (17.2%) (P=0.04), but no patient was diagnosed with antithrombin III deficiency (diagnosis: level<60%). Conclusions: Tests for thrombophilia should be carried out in women with adverse pregnancy outcomes in their history, who are planning pregnancy, to start anticoagulant prophylaxis. Our study supports the thesis that tests for thrombophilia should be carried out in women with a history of adverse pregnancy outcomes and who are planning a pregnancy to start anticoagulant prophylaxis.
