Prenatal echocardiography diagnosis of a novel combination of bilateral ductus arteriosus and cardiovascular anomalies: a case report and literature review. Front Cardiovasc Med 2024; 11:1389759. [PMID: 38784172 PMCID: PMC11111948 DOI: 10.3389/fcvm.2024.1389759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 04/15/2024] [Indexed: 05/25/2024] Open
Abstract
Background Bilateral ductus arteriosus (BDA) is a relatively rare vascular malformation. According to the double arch theory, BDA is formed when the distal ends of the sixth pairs of primitive arches on the left and right sides have not regressed. We describe a fetus with prenatal echocardiographic findings of BDA and right aortic arch mirror-image branching (RAA-MIB) combined with congenital heart disease. Furthermore, to gain a deeper understanding of the embryological mechanism of BDA, we review the literature on all combinations of BDA present in 40 fetuses/infants. Case summary A 22-year-old female patient underwent fetal echocardiography at 23 weeks of gestation. Both the two-dimensional (2D) grayscale image and color Doppler flow imaging (CDFI) revealed dextro-transposition of the great arteries combined with a ventricular septal defect and RAA-MIB. The following scan revealed a rare vascular ring, which was identified as BDA extending from the confluent of the left pulmonary artery and right pulmonary artery, completely encircling the trachea to form an "O"-shaped vascular ring before finally converging into the descending aorta. A persistent left superior vena cava was also observed. We subsequently used four-dimensional (4D) color Doppler imaging with the spatiotemporal image correlation (STIC) HD live flow and STIC HD live flow silhouette mode to clearly display ventricular arterial connectivity and the direction of vessel travel. Adjusting the image quality and display angle is very important when applying STIC. The 4D images confirmed our diagnosis. After multidisciplinary counseling and discussion with her family, this female patient decided to terminate the pregnancy. Conclusion Our review of the literature summarized nine combinations classified into three types of BDA and aortic arch pathology. However, our case differs because it is a novel combination of intracardiac structural abnormalities and vascular rings in a fetus. Prenatal ultrasound diagnosis of BDA is important and requires a combination of 2D grayscale, CDFI, and STIC images to assist in scanning.

Comparing Safety and Efficacy of TACE + Apatinib in Combination with a PD-1 Inhibitor versus a Non-triple Therapy for Treating Advanced Primary Hepatocellular Carcinoma: A Systematic Review and Meta-analysis. JOURNAL OF GASTROINTESTINAL AND LIVER DISEASES : JGLD 2024; 33:85-93. [PMID: 38554419 DOI: 10.15403/jgld-5159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 11/18/2023] [Indexed: 04/01/2024]
Abstract
BACKGROUND AND AIMS This meta-analysis was performed to compare the efficacy and safety of a triple therapy, involving transcatheter arterial chemoembolization (TACE) + apatinib combined with a programmed-cell death protein-1 (PD-1) inhibitor versus TACE + apatinib, a dual therapy with apatinib and PD-1 inhibitor, and TACE alone for the treatment of advanced primary hepatocellular carcinoma (HCC). METHODS A computerized systematic search of databases, such as PubMed, Embase, the Cochrane Library, CNKI, Wanfang Data, and VIP e-Journals was performed to retrieve studies comparing TACE + apatinib combined with a PD-1 inhibitor versus a non-triple therapy for the treatment of advanced primary HCC. The literature search, quality assessment, and data extraction were performed independently by two researchers. Stata 16.0 software was employed to analyze the data. Heterogeneity was assessed utilizing the I2 statistic and p-value, followed by conducting sensitivity analysis. RESULTS A total of 2,352 patients were enrolled from 8 studies, including 900 patients in the triple therapy group of TACE + apatinib combined with a PD-1 inhibitor, 877 patients in the TACE + apatinib group, 52 patients in the apatinib + a PD-1 inhibitor group, and 112 patients in the TACE group. The results revealed that the objective response rate (ORR) was significantly higher in the triple therapy group of TACE + apatinib combined with a PD-1 inhibitor than that in the non-triple therapy group [odds ratio (OR)=2.47, 95% confidence interval (95%CI): 1.61-3.78]. Besides, disease control rate (DCR) was greater in the triple therapy group of TACE + apatinib combined with a PD-1 inhibitor than that in the non-triple therapy group (OR=1.87, 95%CI: 1.44-2.44). Patients in the triple therapy group experienced a significant extension of overall survival (OS) (HR=0.42, 95%CI: 0.36-0.49). In addition, there was no significant difference in the overall rate of adverse events (AEs) between the two groups (OR=1.05, 95%CI: 0.89-1.22). CONCLUSIONS Compared with the non-triple therapy group, the triple therapy group of TACE + apatinib combined with a PD-1 inhibitor outperformed in terms of tumor response and long-term survival with manageable AEs.

Who may benefit from an increased gonadotropin dosing in predicted poor responders undergoing IVF/ICSI? A secondary analysis assessing treatment selection markers of a randomized trial. Eur J Obstet Gynecol Reprod Biol 2023; 291:76-81. [PMID: 37844507 DOI: 10.1016/j.ejogrb.2023.10.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 10/09/2023] [Indexed: 10/18/2023]
Abstract
OBJECTIVE To evaluate whether we can identify patient characteristics that serve as treatment selection markers to distinguish which women with expected poor response benefit from increased dosing of follicle-stimulating hormone (FSH) in terms of improving the cumulative live birth rate compared to standard FSH dosing and which women. STUDY DESIGN We performed a secondary analysis of an RCT performed between March 2019 and October 2021 comparing cumulative live birth after increased dosing (N = 328) who received 225 or 300 IU/day according to their antral follicle count (AFC) and standard dosing (N = 333) who received 150 IU/day of gonadotropin. RESULTS The MFPI analysis showed the benefit of the increased dosing of FSH on cumulative live birth starts to emerge when women were older than 30 years (women > 30 years: 46.5 % vs. 34.2 %; adjusted relative risk (aRR) 1.32, 95 % confidence interval (95 %CI) 1.05-1.66; women ≤ 30 years: 54.7 % vs. 58.6 %; aRR 0.91, 95 % CI 0.72-1.14; p for interaction 0.019). Only those who had AFC between 1 and 3 benefited from the increased FSH dose (AFC 1-3: 38.5 % vs. 6.5 %; aRR 5.88, 95 % CI 1.50-23.15; AFC 4-9: 50.3 % vs. 46.0 %; aRR 1.08, 95 % CI 0.92-1.27; p for interaction 0.023). Expected poor responders defined by the Bologna criteria and POSEIDON criteria did not significantly benefit from the increased dosing of FSH. CONCLUSIONS Women who are aged >30 years or have AFC 1-3 are likely to benefit from increased dosing of FSH by having a higher cumulative live birth rate.

Pre-gravid body mass index is associated with a higher risk of gestational hypertension in singleton pregnancy following frozen-thawed embryo transfer. Front Endocrinol (Lausanne) 2023; 14:1258530. [PMID: 37908745 PMCID: PMC10614010 DOI: 10.3389/fendo.2023.1258530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 09/18/2023] [Indexed: 11/02/2023] Open
Abstract
Introduction Although it is well-known that obesity increases the risk of gestational hypertension (GH) in both spontaneous and assisted reproductive technology (ART) pregnancies. Recent data show that, in ART pregnancies, frozen-thawed embryo transfer (FET) is associated with an even higher risk of GH compared with fresh transfer. However, the relationship between pre-gravid body mass index (BMI) and GH in FET pregnancies has seldom been reported. Objective The aim of this study is to examine the effect of pre-gravid BMI on GH in singleton pregnancy following FET. Methods A retrospective cohort study at a tertiary hospital, including a total of 7,502 women who achieved singleton pregnancy after FET, was included. All patients were enrolled only once. On the basis of the BMI definitions of the Working Group on Obesity in China (WGOC) and the World Health Organization, the women were divided into normal BMI, overweight, and obese groups. The main outcome was GH, and the effect of pre-pregnancy BMI on GH was assessed by generalized linear model. Results The risk of GH in our study population was 6.15%. According to the BMI definitions of the WGOC, the risk of GH in the obese group (15.55%) was significantly higher than that of the overweight group (8.26%, P < 0.001) and the normal BMI group (4.68%, P < 0.001). Pre-gravid overweight and obesity were associated with higher GH risk (OR, 1.77; 95% CI, 1.41-2.20; P < 0.001; OR, 3.69; 95% CI, 2.77-4.91; P < 0.001). A non-linear relationship between pre-gravid BMI and GH was observed. The risk of GH decreased with pre-gravid BMI level up to the turning point of BMI = 28.6 kg/m2 (OR, 1.16; 95% CI, 1.12-1.21; P < 0.001). Conclusion Pre-gravid overweight and obesity are associated with higher GH risk among singleton pregnancy following FET. Before the turning point of BMI = 26.8 kg/m2, the risk of GH may increase 16.4% with each one-unit increment of maternal BMI. Women preparing for FET should maintain a normal BMI to lower the chances of GH.

Nonlinear Relationship Between Maternal and Cord Blood Vitamin B 12 and Folate from a Chinese Population-Based Study. Int J Womens Health 2023; 15:1405-1415. [PMID: 37701181 PMCID: PMC10493199 DOI: 10.2147/ijwh.s420206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Accepted: 08/30/2023] [Indexed: 09/14/2023] Open
Abstract
Purpose There remains a data gap on vitamin B12 and folate level in maternal and child populations. This study aimed to assess the status of vitamin B12 and folate in maternal serum (MS) and umbilical cord serum (UCS). Materials and Methods This was a planned secondary analysis of a case-control study. A total of 858 pregnant women during late pregnancy and their newborns in the hospitals of China were included. Maternal peripheral venous blood and neonatal umbilical cord blood were collected to determine serum vitamin B12 and folate concentration. Relationship of vitamin B12 or folate concentration between MS and UCS was assessed by a quantile regression model and the non-linear relationship between them was examined. Results Nutritional status of serum folate was better than that of vitamin B12. Prevalence of deficiency in MS vitamin B12 and folate was 73.4% and 14.2%, respectively and these figures were about 17.8% and 0.1% in UCS. Both vitamin B12 and folate levels in UCS were significantly higher than those in MS (vitamin B12: 321.0 pg/mL vs 158.3 pg/mL, folate: 16.5 ng/mL vs 7.0 ng/mL, P <0.001). The median UCS-MS ratio of vitamin B12 and folate was 2.0 (95% CI: 1.94-2.06) and 2.4 (95% CI: 2.30-2.53), respectively. The levels of folate and vitamin B12 in UCS increased nonlinearly with their increase in MS which presented an inverted U-shaped curve. Conclusion Deficiency in vitamin B12 and folate in the women during late pregnancy in China is prevalent. Nutritional status of the two vitamins in umbilical cord serum is correlated nonlinearly with that in maternal serum. Folic acid supplementation may be accompanied with vitamin B12 to improve status of vitamin B12 and folate during pregnancy.

Abstract
Aim This study aims to construct a prediction model for histological chorioamnionitis (HCA) and analyze the associations between the predicted risk of HCA and adverse outcomes in preterm infants. Methods In total, 673 subjects were included in this cohort study and divided into HCA group (n = 195) and non-HCA group (n = 478). A stepwise method was used to screen the predictors for HCA, binary logistic regression was used to construct the prediction model, and the associations between the predicted risk of HCA and adverse outcomes were analyzed. Results HCA occurred in 195 patients, accounting for 29.0%. The sensitivity of the prediction model was 0.821 [95% confidence interval (CI): 0.767-0.874)], the specificity was 0.684 (95% CI: 0.642-0.726), the positive predictive value was 0.514 (0.459-0.570), the negative predictive value was 0.903 (95% CI: 0.873-0.934), the area under the curve was 0.821 (95% CI: 0.786-0.855), and the accuracy was 0.724 (95% CI: 0.690-0.757). The predicted risk of HCA was associated with a higher risk of bronchopulmonary dysplasia (BPD) [odds ratio (OR) = 3.48, 95% CI: 1.10-10.95)], sepsis (OR = 6.66, 95% CI: 2.17-20.43), and neonatal infections (OR = 9.85, 95% CI: 3.59-26.98), but not necrotizing enterocolitis (OR = 0.67, 95% CI: 0.24-1.88), retinopathy of prematurity (OR = 1.59, 95% CI: 0.37-6.85), and brain damage (OR = 1.77, 95% CI: 0.82-3.83). After adjusting for confounders including gestational week at birth and birth weight, the risk of neonatal infections (OR = 5.03, 95% CI: 2.69-9.41) was increased in preterm infants' exposure to HCA. Conclusion The model showed good predictive performance for identifying pregnant women with a higher risk of HCA. In addition, HCA was associated with the risk of BPD, sepsis, and infections in neonates.

The Interactions between Maternal Iron Supplementation and Iron Metabolism-Related Genetic Polymorphisms on Birth Outcomes: A Prospective Study in Chinese. J Nutr 2023; 153:2442-2452. [PMID: 37390907 DOI: 10.1016/j.tjnut.2023.06.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 06/14/2023] [Accepted: 06/26/2023] [Indexed: 07/02/2023] Open
Abstract
BACKGROUND The effect of iron supplementation during pregnancy on birth outcomes may vary with maternal genetic background and needs more investigation. OBJECTIVES This prospective study aimed to evaluate the interactions between maternal iron supplementation and iron metabolism-related genetic polymorphisms on birth outcomes. METHODS This was a substudy from a community-based randomized control trial conducted in Northwest China, which included 860 women from the 2 micronutrient supplementation groups (folic acid [FA] and FA + iron group). Maternal peripheral blood, sociodemographic and health-related information, and neonatal birth outcomes were collected. Six single nucleotide polymorphisms in iron metabolism-related genes were genotyped. The alleles associated with decreased iron/hemoglobin status were used as the effect alleles. The genetic risk score (GRS) that reflected the genetic risk of low iron/hemoglobin status was estimated using the unweighted and weighted methods. Generalized estimating equations with small-sample corrections were applied to evaluate the interactions between iron supplementation and SNPs/GRS on birth outcomes. RESULTS There were significant interactions between maternal iron supplementation and rs7385804 (P = 0.009), rs149411 (P = 0.035), rs4820268 (P = 0.031), the unweighted GRS (P = 0.018), and the weighted GRS (P = 0.009) on birth weight. Compared with FA supplementation only, FA + iron supplementation significantly increased birth weight among women with more effect alleles in rs7385804 (β: 88.8 g, 95% CI: 9.2, 168.3) and the GRSs (the highest unweighted GRS, β: 135.5 g, 95% CI: 7.7, 263.4; the highest weighted GRS, β: 145.9 g, 95% CI: 43.4, 248.5); it had a trend of decreasing birth weight and increasing low birth weight risk among women with fewer effect alleles. CONCLUSIONS In our population, maternal genetic background related to iron metabolism plays a significant role in determining the efficacy of iron supplementation. Routine iron supplementation could be more beneficial to fetal weight growth among mothers with higher genetic risk for low iron/hemoglobin status.

JOURNAL OF GASTROINTESTINAL AND LIVER DISEASES : JGLD 2023; 32:182-189. [PMID: 37345608 DOI: 10.15403/jgld-4667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 03/19/2023] [Indexed: 06/23/2023]
Abstract
AIMS To compare the effectiveness and safety of transarterial chemoembolization (TACE) combined with apatinib plus camrelizumab (TACE+AC) versus TACE combined with apatinib alone (TACE+A) for patients with advanced HBV-related hepatocellular carcinoma (HBV-HCC). METHODS The clinical data of patients with HBV-HCC who received either TACE+AC or TACE+A treatment were retrospectively analyzed. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) were compared between the two groups. Multivariate Cox proportional hazards model regression analysis was used to identify the independent prognostic factors of OS. RESULTS Between March 2019 to January 2022, 76 patients were assigned to the TACE+AC group (n = 37) and the TACE+A group (n=39). The median OS and PFS in the TACE+AC group were significantly longer than those in the TACE+A group (OS, 15.4 vs. 11.3 months; p=0.008; PFS, 7.4 vs. 5.1 months; p=0.001) and the ORR and DCR in the TACE + AC group were significantly greater than those in the TACE+A group (ORR, 43.2% vs. 20.5%; p=0.033; DCR, 67.6% vs. 43.6%; p=0.036). There was no significant difference in the incidence of grade ≥3 AEs between the two groups (p=0.483). Multivariate regression analysis identified the treatment modalities, AFP level, and extrahepatic metastasis as independent prognostic factors (p<0.05). CONCLUSION TACE+AC significantly improved the clinical outcomes of patients with HBV-HCC and elicited relatively controllable AEs.

Abstract
BACKGROUND AND AIMS To compare the efficacy and safety of transarterial chemoembolization (TACE) + lenvatinib (TACE+L) versus lenvatinib (L) monotherapy in the treatment of advanced hepatocellular carcinoma by a meta-analysis. METHODS PubMed, Embase, the Cochrane Library, CNKI, VIP e-Journals Database, and Wanfang Data were systematically searched to collate literature comparing TACE+L with L alone for the treatment of advanced liver cancer. The literature search, quality assessment, and data extraction were performed independently by two reviewers. The Stata 16 software package was used to process and analyze the data. We assessed heterogeneity using both I2 and the p-value, performed a publication bias assessment, and conducted a sensitivity analysis. RESULTS Five studies were finally included, including one randomized controlled study and four retrospective studies; these involved a total of 1,167 patients, including 523 patients in the TACE+L combination group and 644 patients in the L monotherapy group. In this meta-analysis, the TACE+L group showed a significantly better objective response rate (ORR) (OR=2.54, 95%CI: 1.34 - 4.80) and disease control rate (DCR) compared to the L monotherapy group (OR=2.68, 95%CI: 1.75 - 4.08). The combined group had significantly improved progression-free survival (PFS) (HR=0.47, 95%CI: 0.40 - 0.56) and overall survival (OS) (HR=0.48, 95%CI: 0.39-0.59). In addition, there was no significant difference found in the overall adverse events of any grade between the two groups (OR=1.13, 95%CI: 0.99 - 1.29). CONCLUSIONS Compared to L alone, TACE+L treatment resulted in better tumor response, better long-term survival, and was accompanied by controllable adverse events.

Abstract
OBJECTIVES Diet is one of the main risk factors for cardiovascular disease (CVD), while the evidence about the relationship between dietary pattern (DP) and CVD in children is scarce. This study aims to explore the association between DP and CVD risk in children. STUDY DESIGN This was a cross-sectional and longitudinal study. METHODS This research was conducted among 4351 children aged 6-12 years old in 2014, then the subgroup children in 2014 were followed up in 2019. Dietary intakes were assessed using a food frequency questionnaire. DP was clustered based on 15 food items, and finally, four main DPs were obtained. RESULTS Four major DPs were identified: (1) low intake of nuts and algae pattern, (2) low-energy intake pattern, (3) high-energy intake pattern, and (4) regular DP. Compared with the regular diet pattern, the low intake of nuts and algae pattern was associated with the increased risk of higher systolic blood pressure (107.71 mm Hg vs 105.78 mm Hg, P < 0.001), diastolic blood pressure (64.98 mm Hg vs 63.91 mm Hg, P = 0.0056), hypertension (odds ratio [OR]:1.44, 95% confidence interval [CI]: 1.10, 1.88; P = 0.0036), dyslipidemia (OR: 2.41, 95% CI: 1.28, 4.52; P = 0.0194), and obesity (OR: 1.48, 95% CI: 1.16, 1.89; P = 0.0003) in children from a cross-sectional aspect in 2014 and it was also found associated with an increased risk of hypertension (OR: 2.67, 95% CI: 1.45, 4.92; P = 0.0017) in 2019. CONCLUSIONS Low nuts and algae intake combinations in children seemed associated with increased CVD risk. Such findings are imperative for national development of dietary recommendation for the prevention of CVDs.

Abstract
BACKGROUND Congenital heart disease (CHD) is the most prevalent birth defect in recent decades. The aim of this research was to examine the association between maternal housing renovation exposure during the periconceptional period and isolated congenital heart disease (CHD) in their offspring. METHODS A multi-hospitals case-control study was conducted from six tertiary A hospitals in Xi'an, Shaanxi, Northwest China based on questionnaires and interviews to address this question. The cases included fetuses or newborns diagnosed with CHD. Controls consisted of healthy newborns without birth defects. In total, 587 cases and 1180 controls were enrolled in this study. The association between maternal periconceptional housing renovation exposure and isolated CHD for offspring was assessed by estimating odds ratios (OR) with multivariate logistic regression models. RESULTS After adjusting for potential confounding variables, it was found that maternal exposure to home improvement projects was associated with a higher probability of isolated CHD in offspring (adjusted OR: 1.77, 95% CI: 1.34, 2.33). Additionally, the risk of the ventricular septal defect (VSD) and patent ductus arteriosus (PDA) for CHD types was significantly associated with maternal exposure to housing renovations (VSD: adjusted OR = 1.56, 95% CI: 1.01, 2.41; PDA: adjusted OR = 2.50, 95% CI: 1.41, 4.45). CONCLUSIONS Our study suggests that maternal exposure to housing renovation during the periconceptional period was associated with an increased risk of isolated CHD in offspring. Consequently, it would be beneficial to avoid living in a renovated home from 12 months before pregnancy through the first trimester to lower isolated CHD in infants.

Abstract
OBJECTIVE To evaluate, in women scheduled for IVF with predicted poor ovarian response, the effect of increased dosing of gonadotropin on maternal and neonatal outcomes compared with standard dosing. STUDY DESIGN We performed a follow-up study of an open-labelled randomized controlled trial comparing increased (225 or 300 IU/d) versus standard (150 IU/d) dose gonadotrophins on cumulative live birth rates. We randomized 661 women with a predicted poor ovarian response (based on their antral follicle count) scheduled for their first IVF/ICSI cycle. Here, we report on maternal and neonatal outcomes between increased and standard dosing groups. RESULTS There was a trend of increased risk of gestational diabetes mellitus in the increased gonadotrophin dose group compared with the standard group in both cumulative live birth pregnancies (14.8% vs. 7.8%, relative risk (RR) 1.90, 95% confidence interval (CI) 0.96-3.74, P = 0.06) and live birth pregnancies in the first transfer (15.2% vs. 7.7%, RR 1.98, 95 %CI 0.93-4.19, P = 0.08), without reaching statistical significance. The occurrence of gestational diabetes mellitus was significantly higher in the increased gonadotrophin dose group (24/149, 16.1% vs. 8/128, 6.3%; risk ratio (RR) 2.58, 95 %CI 1.19 to 5.54, P = 0.02) in singleton pregnancies. In women with first embryo transfer cycle, maternal hypothyroidism occurred also more frequent in the increased gonadotrophin dose group than the standard group (16.0% vs. 6.8%, RR 2.34, 95 %CI:1.07-5.11, P = 0.03). CONCLUSIONS In women with predicted poor ovarian response, increased dosing of gonadotropin may result in an increased risk of gestational diabetes mellitus and maternal hypothyroidism.

Association between Maternal Blood Glucose Levels during Pregnancy and Birth Outcomes: A Birth Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:2102. [PMID: 36767469 PMCID: PMC9915873 DOI: 10.3390/ijerph20032102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 01/16/2023] [Accepted: 01/16/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVE This study aimed to investigate the relationship between maternal blood glucose levels during pregnancy and neonatal birth outcomes in Northwest China. METHODS This population-based cohort study included 10,010 first-trimester pregnant women who joined the birth cohort of the Northwest Women's and Children's Hospital from July 2018 to July 2020. Basic demographic characteristics, lifestyle and behavior patterns were collected. Oral glucose tolerance test (OGTT) results during the second trimester and pregnancy outcomes after childbirth were also collected. A generalized linear model was constructed to analyze the effects of blood glucose levels on neonatal birth outcomes. RESULTS We found that every 1 mmol/L increase in fasting plasma glucose (FPG) was associated with an increase in birth weight (β = 100.22 g, 95% confidence interval (95%CI): 81.91, 118.52), birth weight Z score (β = 0.23, 95%CI: 0.19, 0.27) and birth weight Z centile (β = 6.72%, 95%CI: 5.51, 7.94). Moreover, the risk of macrosomia, premature birth and being born large for gestational age (LGA) increased by 2.01 (95%CI: 1.67, 2.43), 1.35 (95%CI: 1.09, 1.66) and 1.80 (95%CI: 1.57, 2.07) times, respectively. Additionally, for every 1 mmol/L increase in FPG associated with a decrease in gestational age (β = -0.12 weeks, 95%CI: -0.19, -0.06), the risk of SGA decreased by 0.70 (OR = 0.70, 95%CI: 0.55, 0.89) times. Every 1 mmol/L increase in 1/2-h PG had similar outcomes as FPG, besides premature birth and SGA. CONCLUSIONS Higher blood glucose in pregnant women may increase neonatal birth weight, decrease gestational age and lead to a higher risk of macrosomia, premature birth and LGA. Mothers should actively prevent and control hyperglycemia to promote maternal and infant health.

Hormone replacement treatment regimen is associated with a higher risk of hypertensive disorders of pregnancy in women undergoing frozen-thawed embryo transfer. Front Endocrinol (Lausanne) 2023; 14:1133978. [PMID: 36909329 PMCID: PMC9998903 DOI: 10.3389/fendo.2023.1133978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 02/13/2023] [Indexed: 03/14/2023] Open
Abstract
INTRODUCTION In frozen-thawed embryo transfer (FET) cycles, hormone replacement treatment (HRT) was associated with a higher risk of hypertensive disorders of pregnancy (HDP) compared with natural cycles (NC). Multiple pregnancy was a risk factor for HDP and several studies did not conduct subgroup analysis of singleton pregnancy and multiple pregnancy. OBJECTIVE To investigate whether HRT regimen could be a risk factor for HDP in women undergoing FET cycles in singleton and twin pregnancies. METHODS A retrospective cohort study at a tertiary hospital, including a total of 9120 women who underwent FET and achieved ongoing pregnancy; 7590 patients underwent HRT-FET and 1530 NC-FET. The main outcome was HDP. HDP were analyzed for singleton and twin pregnancies, respectively. RESULTS In the singleton pregnancy, the risk of HDP in the HRT-FET group was significantly higher than that in the NC-FET group (6.21% vs. 4.09%; P=0.003). After adjusting for female age oocyte pick up, female age at FET and body mass index (BMI), HRT was found as a risk factor for HDP (adjusted odds ration [aOR]: 1.43; 95% confidence interval [CI]: 1.07 to 1.91; P=0.017). In the multiple pregnancy, the risk of HDP in the HRT-FET and NC-FET groups was similar. CONCLUSION HRT was associated with a higher risk of HDP in women who underwent FET and achieved singleton pregnancy.

Abstract
Fractional calculus plays an increasingly important role in mechanics research. This review investigates the progress of an interdisciplinary approach, fractional plasticity (FP), based on fractional derivative and classic plasticity since FP was proposed as an efficient alternative to modelling state-dependent nonassociativity without an additional plastic potential function. Firstly, the stress length scale (SLS) is defined to conduct fractional differential, which influences the direction and intensity of the nonassociated flow of geomaterials owing to the integral definition of the fractional operator. Based on the role of SLS, two branches of FP, respectively considering the past stress and future reference critical state can be developed. Merits and demerits of these approaches are then discussed, which leads to the definition of the third branch of FP, by considering the influences of both past and future stress states. In addition, some specific cases and potential applications of the third branch can be realised when specific SLS are adopted.

Abstract
INTRODUCTION Natural cycle (NC) and hormone replacement treatment (HT) are frequently used endometrial preparation protocols prior to frozen-thawed embryo transfer in ovulatory women. It is not clear which protocol results in a higher live birth rate. It has been suggested that there is an increased risk in maternal and perinatal morbidity following HT protocol due to the lack of corpus luteum. The objective of this trial is to compare the clinical outcomes of NC and HT protocols in frozen embryo transfer. METHODS AND ANALYSIS COMPETE is an open-label, single-centre, randomised controlled trial targeting to recruit 888 women, with 444 women each in two arms (1:1 treatment ratio). Women undergoing in vitro fertilisation scheduled for a frozen embryo transfer and have a regular menstrual cycle are eligible. Exclusion criteria include ovulation disorders and intrauterine adhesions. The primary outcome is live birth resulting from the first frozen embryo transfer after randomisation. Secondary outcomes include biochemical pregnancy, clinical pregnancy, multiple pregnancy, ongoing pregnancy, miscarriage, endometrial thickness, cycle cancellation, gestational diabetes mellitus, hypertensive disorders of pregnancy, antepartum haemorrhage, preterm birth, birth weight, large for gestational age, congenital anomaly and perinatal mortality. The data analysis will be following the intention-to-treat principle. ETHICS AND DISSEMINATION This study has been approved by the Institutional Review Board of Northwest women's and children's hospital (2020008). Written informed consent will be obtained from each participant before randomisation. The results of the trial will be presented via publications. TRIAL REGISTRATION NUMBER ChiCTR2000040640.

Abstract
Currently, more and more studies suggested that reductionism was lack of holistic and integrative view of biological processes, leading to limited understanding of complex systems like microbiota and the associated diseases. In fact, microbes are rarely present in individuals but normally live in complex multispecies communities. With the recent development of a variety of metaomics techniques, microbes could be dissected dynamically in both temporal and spatial scales. Therefore, in-depth understanding of human microbiome from different aspects such as genomes, transcriptomes, proteomes, and metabolomes could provide novel insights into their functional roles, which also holds the potential in making them diagnostic biomarkers in many human diseases, though there is still a huge gap to fill for the purpose. In this mini-review, we went through the frontlines of the metaomics techniques and explored their potential applications in clinical diagnoses of human diseases, e.g., infectious diseases, through which we concluded that novel diagnostic methods based on human microbiomes shall be achieved in the near future, while the limitations of these techniques such as standard procedures and computational challenges for rapid and accurate analysis of metaomics data in clinical settings were also examined.

Cooking stoves and risk of congenital heart disease in Northwest China: A case-control study. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 816:151564. [PMID: 34762962 DOI: 10.1016/j.scitotenv.2021.151564] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Revised: 10/30/2021] [Accepted: 11/05/2021] [Indexed: 06/13/2023]
Abstract
Congenital heart disease (CHD) has become the most common birth defect in recent decades. The aim of our study was to examine the association between stove cooking by women during pregnancy and congenital heart disease in their offspring. To address this question, we conducted a case-control study from 2014 to 2016 in Xi'an, Shaanxi, Northwest China, investigating 326 cases and 1071 controls. The cases included fetuses or newborns diagnosed with CHD based on the International Classification of Disease (ICD)-10. Controls consisted of healthy newborns without birth defects. Multivariate unconditional logistic regression was applied to analyze the effects of stove cooking before and during pregnancy on CHD in offspring. After adjusting for confounding factors, we found that, compared to cooking with gas stoves, electromagnetic, coal, and firewood stoves during pregnancy was associated with increased risk of CHD in offspring [electromagnetic stove (odds ratio (OR): 2.89, 95% confidence interval (CI): 2.02, 4.12); coal stove (OR: 3.94, 95% CI: 2.33, 6.65); firewood stove (OR: 6.74, 95% CI: 3.03, 15.00)]. Additionally, higher cooking frequency was associated with increased risk of CHD [total stoves (OR: 2.27, 95% CI: 1.57, 3.28); gas stove (OR: 2.38, 95% CI: 1.43, 3.95); electromagnetic stove (OR: 2.46, 95% CI: 1.32, 4.58); coal and firewood stoves (OR: 3.09, 95% CI: 1.01, 9.46)]. Our study suggests that using electromagnetic, coal, and firewood stoves for cooking during pregnancy and greater cooking frequency increased the risk of CHD in offspring. More attention to the choice of fuels in cooking by pregnant women would help to reduce the incidence of CHD in children.

Associations of B Vitamin-Related Dietary Pattern during Pregnancy with Birth Outcomes: A Population-Based Study in Northwest China. Nutrients 2022; 14:nu14030600. [PMID: 35276959 PMCID: PMC8838836 DOI: 10.3390/nu14030600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 01/26/2022] [Accepted: 01/27/2022] [Indexed: 02/04/2023] Open
Abstract
This study aimed to derive a maternal dietary pattern to explain the variation in B vitamins during pregnancy and to investigate this pattern in relation to birth outcomes. A total of 7347 women who gave birth to live newborns less than one year were included. Their dietary pattern during pregnancy was derived using the reduced-rank regression method with six B vitamins as response variables. Associations between dietary pattern score and birth weight, gestational age at delivery, birth weight Z score, low birth weight, preterm, and small-for-gestational-age (SGA) were estimated using generalised linear mixed models. We identified a high B-vitamin dietary pattern characterised by high intakes of animal foods, vegetables, fungi and algae, legumes, and low intakes of oils and cereals. Women in the highest quartile of this pattern score had newborns with a 44.5 g (95% CI: 13.8, 75.2 g) higher birth weight, 0.101 (95% CI: 0.029, 0.172) higher birth weight Z score, and 27.2% (OR: 0.728; 95% CI: 0.582, 0.910) lower risk of SGA than those in the lowest quartile. Our study suggested that adherence to the high B-vitamin dietary pattern during pregnancy was associated with a higher birth weight and a lower risk of SGA.

Abstract
OBJECTIVE Predictive models of the cumulative live birth (CLB) in women undergoing in vitro fertilization (IVF) treatment are limited. The aim of this study was to develop and validate a nomogram for the CLB in women undergoing the first IVF cycle. METHODS Based on a cross-sectional study in assisted reproduction center of Northwest Women's and Children's Hospital, 26,689 Chinese patients who underwent IVF treatment was used to develop and validate a prediction model for the CLB. Among those participants, 70% were randomly assigned to the training set (18,601 patients), while the remaining 30% were assigned to the validation set (8,088 patients). A nomogram was constructed based on the results of the multivariate logistic regression analysis. The model performance was evaluated using the C statistic and the calibration performance was assessed by Hosmer-Lemeshow (HL) χ2 statistics and calibration plots. RESULTS Multivariate logistic regression analyses revealed that female age, female body mass index (BMI), tubal factor infertility, male infertility, uterine factor infertility, unexplained infertility, antral follicle count (AFC) and basal serum follicle stimulating hormone (FSH) were significant factors for CLB in women undergoing the first IVF cycle. An area under the receiver operating characteristic curve (AUC) in the prediction model was 0.676 (95% CI 0.668 to 0.684) in the training group. The validation set showed possibly helpful discrimination with an AUC of 0.672 (95% CI 0.660 to 0.684). Additionally, the prediction model had a good calibration (HL χ2 = 8.240, P=0.410). CONCLUSIONS We developed and validated a nomogram to predict CLB in women undergoing the first IVF cycle using a single center database in China. The validated nomogram to predict CLB could be a potential tool for IVF counselling.

Abstract
Background Previous studies have suggested that maternal stress could increase the risk of some adverse pregnancy outcomes, but evidence on congenital heart disease (CHD) is limited. We aimed to explore the association between maternal exposure to life events during pregnancy and CHD in offspring. Methods The data was based on an unmatched case-control study about CHD conducted in Shaanxi province of China from 2014 to 2016. We included 2280 subjects, 699 in the case group and 1581 in the control group. The cases were infants or fetuses diagnosed with CHD, and the controls were infants without any birth defects. The life events were assessed by the Life Events Scale for Pregnant Women, and were divided into positive and negative events for synchronous analysis. A directed acyclic graph was drawn to screen the confounders. Logistic regression was employed to estimate the odds ratio and 95% confidence interval for the effects of life events on CHD. Results After controlling for the potential confounders, the pregnant women experiencing the positive events during pregnancy had lower risk of CHD in offspring than those without positive events (OR = 0.38, 95%CI: 0.30 ~ 0.48). The risk of CHD in offspring could increase by 62% among the pregnant women experiencing the negative events compared to those without (OR = 1.62, 95%CI: 1.29 ~ 2.03). Both effects showed a certain dose-response association. Besides, the positive events could weaken the risk impact of negative events on CHD. Conclusion It may suggest that maternal exposure to negative life events could increase the risk of CHD in offspring, while experiencing positive events could play a potential protective role.

Abstract
BACKGROUND/OBJECTIVES To examine the effect of pre-pregnancy maternal body mass index (BMI) on neonatal weight outcomes of twin infants who were conceived by assisted reproductive technology (ART). SUBJECTS/METHODS A 10-year (2006-2015) Chinese sample of 3431 mothers and their twin infants conceived by ART from a retrospective cohort were included. The effects of pre-pregnancy maternal BMI on gestational age and birth weight were assessed by generalized linear model and generalized estimating equation model. RESULTS Compared with a normal weight group, pre-pregnancy maternal underweight was associated with lower birth weight and increased risk of small for gestational age (SGA) in twins conceived by ART (birth weight: difference -59.22 g, 95% CI -93.16 to -25.27 g; SGA: RR 1.25, 95% CI 1.09 to 1.43). Pre-pregnancy maternal obesity was associated with higher birth weight and increased risk of preterm birth (birth weight: difference 65.82 g, 95% CI 10.66 to 120.99 g; preterm birth: RR 1.19, 95% CI 1.03-1.37). A nonlinear relationship between pre-pregnancy maternal BMI and SGA was observed. The risk of SGA decreased with the pre-pregnancy maternal BMI up to the turning point (BMI = 21) (RR 0.90, 95% CI 0.86-0.95). CONCLUSIONS Among mothers undergoing ART, pre-pregnancy maternal obesity is associated with higher birth weight and higher risk of preterm birth for twin pregnancy, and pre-pregnancy maternal underweight is associated with lower birth weight and higher risk of SGA. Women preparing for ART should maintain a normal BMI to lower the chances of adverse neonatal outcomes.

Abstract
Objective: To explore the effects of narrative therapy on cognition, emotion and treatment satisfaction of convalescent patients with occupational acute chemical toxic encephalopathy. Methods: From June to July 2019, 60 convalescent patients with occupational chemical poisoning encephalopathy were randomly divided into narrative group and control group, with 30 cases in each group. The control group received routine clinical treatment. On the basis of receiving the original clinical treatment, patients in the narrative group added narrative treatment once a week to explain discomfort in specific life situations through conversation from the perspective of disease and psychology. 30 min each time for 6 weeks. The patients were investigated with Montreal Cognitive Assessment Scale (MoCA scale) every 2 weeks to evaluate the degree of cognitive impairment. The changes of depression, anxiety and treatment satisfaction were investigated before and after intervention. Results: There was no significant difference in MoCA scores between the two groups before intervention (P>0.05) . After 6 weeks of treatment, MoCA scores of narrative group and control group gradually increased with the extension of treatment time, and the increase degree of MoCA score of narrative group was greater than that of control group (P<0.01) . Before intervention, there was no significant difference in depression, anxiety score, prevalence and satisfaction index between narrative group and control group (P>0.05) . After the intervention, the scores and prevalence of depression and anxiety in the narrative group were significantly lower than those in the control group, and the scores of feeling in the process of seeing a doctor and how to obtain their own disease information were significantly higher than those in the control group (P<0.05) . Conclusion: Narrative therapy can improve the cognitive function and emotion of patients with occupational chemical poisoning, and improve the treatment satisfaction of patients.

Abstract
Background For most women who have had a previous cesarean section, vaginal birth after cesarean section (VBAC) is a reasonable and safe choice, but which will increase the risk of adverse outcomes such as uterine rupture. In order to reduce the risk, we evaluated the factors that may affect VBAC and and established a model for predicting the success rate of trial of the labor after cesarean section (TOLAC). Methods All patients who gave birth at Northwest Women’s and Children’s Hospital from January 2016 to December 2018, had a history of cesarean section and voluntarily chose the TOLAC were recruited. Among them, 80% of the population was randomly assigned to the training set, while the remaining 20% were assigned to the external validation set. In the training set, univariate and multivariate logistic regression models were used to identify indicators related to successful TOLAC. A nomogram was constructed based on the results of multiple logistic regression analysis, and the selected variables included in the nomogram were used to predict the probability of successfully obtaining TOLAC. The area under the receiver operating characteristic curve was used to judge the predictive ability of the model. Results A total of 778 pregnant women were included in this study. Among them, 595 (76.48%) successfully underwent TOLAC, whereas 183 (23.52%) failed and switched to cesarean section. In multi-factor logistic regression, parity = 1, pre-pregnancy BMI < 24 kg/m2, cervical score ≥ 5, a history of previous vaginal delivery and neonatal birthweight < 3300 g were associated with the success of TOLAC. The area under the receiver operating characteristic curve in the prediction and validation models was 0.815 (95% CI: 0.762–0.854) and 0.730 (95% CI: 0.652–0.808), respectively, indicating that the nomogram prediction model had medium discriminative power. Conclusion The TOLAC was useful to reducing the cesarean section rate. Being primiparous, not overweight or obese, having a cervical score ≥ 5, a history of previous vaginal delivery or neonatal birthweight < 3300 g were protective indicators. In this study, the validated model had an approving predictive ability. Supplementary Information The online version contains supplementary material available at 10.1186/s12884-021-04004-z.

Changes in Mental Health of Women Undergoing Assisted Reproductive Technology Treatment During the COVID-19 Pandemic Outbreak in Xi'an, China. Front Public Health 2021; 9:645421. [PMID: 34113596 PMCID: PMC8185191 DOI: 10.3389/fpubh.2021.645421] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 04/19/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: To investigate the mental health of women undergoing assisted reproductive technology (ART) treatment during the novel coronavirus pneumonia (COVID-19) pandemic outbreak in Xi'an, China. Methods: A repeated cross-sectional study was administered to women undergoing ART treatment during the outbreak period (599 women in February 2020) and the control period (892 women in May 2020) at the Northwest Women's and Children's Hospital, Xi'an, China. Results: Both the ART-treated women surveyed during the outbreak period and those surveyed during the control period had high scores on the fear dimension (0.88, 0.51). The total scores for mental health among the participants during the control period were lower than those during the outbreak period (difference = -0.22; 95% CI = -0.25, -0.18). Lower scores were also seen during the control period, compared to those in the outbreak period, for depression (difference = -0.18; 95% CI = -0.23, -0.13), neurasthenia (difference = -0.31; 95% CI = -0.36, -0.25), fear (difference = -0.37; 95% CI = -0.43, -0.31), compulsion anxiety (difference = -0.13; 95% CI = -0.16, -0.09), and hypochondriasis (difference = -0.09; 95% CI = -0.12, -0.06). Conclusions: During the COVID-19 global pandemic, the mental health of women undergoing ART treatment in Xi'an, China, was primarily manifested as fear. As the pandemic was brought under control, the mental health of ART-treated women improved. As evidenced by these results, the COVID-19 pandemic influences the mental health of women undergoing ART treatment, and clinicians should be aware of this for similar future situations.

Abstract
OBJECTIVE To observe the effect of adiponectin on osteogenesis in type 2 diabetic rats. METHODS The 4th-week-old male SD rats were divided into normal control group (n=18) and diabetic model group (n = 42). Type 2 diabetes was induced by high-fat and high-sugar diet and intraperitoneal injection of a low dose of streptozotocin (STZ). The successfully-induced diabetic rats were divided into diabetic group (DM=18) and adiponectin intervention group (APN=18). APN group was injected with APN 10 μg/kg*d. The rats were separately sacrificed at the 4th, 8th and 12th week after the intervention. Bone microstructure and adipose tissue were observed via HE staining. Bone marrow was extracted from one side of the femur, and the supernatant was achieved by centrifugation. After BMD assessed by DXA, the other side of the femur was for further HE staining. Runx-2 expression in the bone marrow cells was detected by RT-PCR. BALP and AOPPs in bone marrow supernatant were assayed by ELISA. AGEs were detected by immunohistochemical staining. RESULTS With the feeding time over, blood glucose, AOPP, and AGEs were increased, and Runx-2 mRNA, BALP, BMD were decreased in diabetic rat group(P<0.05). Oxidative stress (OS) maker (AOPP) was decreased and osteogenesis makers (Runx2 mRNA, BALP) were increased after intervention with exogenous adiponectin (P<0.05). At the 8th and 12th week, the trabecular bone became thinner and broken, and the fat cell number increased in all 3 groups, especially in the DM group. The adiponectin intervention group showed that the trabecular bone structure was moderately restored. CONCLUSIONS OS is obvious in bone micro-environment in diabetic rats. OS may have an inhibitory effect on regulation of osteogenic differentiation factor Runx2, causing down regulation of osteoblast differentiation and bone formation. Adiponectin may improve OS response and protect the bone structure.

Association between neighborhood aesthetics and childhood obesity. Obes Rev 2021; 22 Suppl 1:e13079. [PMID: 32725796 PMCID: PMC7988560 DOI: 10.1111/obr.13079] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Accepted: 05/18/2020] [Indexed: 12/31/2022]
Abstract
The lack of neighbourhood aesthetics (e.g. public art and well-maintained properties) may reduce walkability in the neighbourhood and increase the risk of childhood obesity. In this study, a literature search was conducted in the Cochrane Library, PubMed and Web of Science for articles published before January 1, 2019 to analyse the associations between neighbourhood aesthetics and weight-related behaviours and outcomes among children and adolescents aged <18. One cohort study and 24 cross-sectional studies, conducted in 10 countries with a median sample size of 1124 were identified. Neighbourhood aesthetics was more commonly assessed by self-reported or parent-reported perceptions than objective measurements. Eighteen of the 25 included studies analysed physical activity (PA) as the outcome of interests, eight studies analysed active transport to school (ATS), and eight studies analysed weight status, including body mass index and overweight/obesity status. About two-thirds of studies reported non-significant associations when using PA and weight status as outcomes, and half of studies showed that neighbourhood aesthetics is associated with increased use of ATS. The rest of the studies reported mixed findings with slightly more studies showing neighbourhood aesthetics may promote PA or reduce weight. Better designed studies are necessary to achieve a robust understanding of this epidemiological relationship in the future.

Regulator of cullins-1 (ROC1) negatively regulates the Gli2 regulator SUFU to activate the hedgehog pathway in bladder cancer. Cancer Cell Int 2021; 21:75. [PMID: 33499884 PMCID: PMC7836478 DOI: 10.1186/s12935-021-01775-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 01/16/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The regulator of cullins-1 (ROC1) is an essential subunit in the cullin-RING ligase (CRL) protein complex and has been shown to be critical in bladder cancer cell survival and progression. This study aimed to explore the molecular mechanism of ROC1 action in the malignant progression of bladder cancer. METHODS This study utilized ex vivo, in vitro, and in vivo nude mouse experiments to assess the underlying mechanisms of ROC1 in bladder cancer cells. The expression of the components of the sonic hedgehog (SHH) pathway was determined by western blot analysis. ROC1 expression in human tumors was evaluated by immunohistochemistry. RESULTS ROC1 overexpression promoted the growth of bladder cancer cells, whereas knockdown of ROC1 expression had the opposite effect in bladder cancer cells. Mechanistically, ROC1 was able to target suppressor of fused homolog (SUFU) for ubiquitin-dependent degradation, allowing Gli2 release from the SUFU complex to activate the SHH pathway. Furthermore, knockdown of SUFU expression partially rescued the ROC1 knockdown-suppressed SHH activity as well as cancer cell growth inhibition. In ex vivo experiments, tissue microarray analysis of human bladder cancer specimens revealed a positive association of ROC1 expression with the SHH pathway activity. CONCLUSION This study demonstrated that dysregulation of the ROC1-SUFU-GLI2 axis plays an important role in bladder cancer progression and that targeting ROC1 expression is warranted in further investigations as a novel strategy for the future control of bladder cancer.

Abstract
The large-scale Xi'an longitudinal mother-child cohort study has started to enroll pregnant women who attended Northwest Women's and Children's Hospital (NWCH) for antenatal care in early pregnancy (less than 20 weeks' gestation) from January 2013 and the enrollment will be ended in January 2023. We aimed to investigate the role of external factors (i.e., diet and environment) and internal (i.e., biological, genetic and epigenetic) on the short- and long-term outcomes of mothers and children up to at least 12 years. Mothers completed all routine prenatal care during pregnancy and four times of follow-up at 42 days, 3, 6 and 12 years after delivery, respectively. For children, birth information were obtained from routine medical records and the follow-up information were obtained from child health care clinics of NWCH at age 42 days, 6, 12 and 24 months, then by interviewing mothers every two years until 12 years old. A range of data (including biological, demographic, birth outcomes/birth defects and nutritional factors from both maternal and off-spring) were collected by both interviews and laboratory tests. By June 30th 2019, a total of 114,946 mothers and 124,454 live births had been recruited.

Abstract
OBJECTIVE To investigate the association between pre-pregnancy body mass index (BMI) and miscarriages in women who required assisted reproductive technology (ART) for conception. METHODS A retrospective cohort study was conducted using a 10-year (2006-2015) sample of 14,994 pregnancy cycles with ART treatment in Northwest Women's and Children's Hospital, Xi'an, China. The effects of women's BMI before pregnancy on early miscarriage and miscarriage were assessed using generalized estimating equation models. RESULTS The risks of early miscarriage and miscarriage were higher in the obese group than in the normal weight group [early miscarriage: relative risk (RR) = 1.36, confidence interval (CI): 1.12-1.65; miscarriage: RR = 1.40, 95% CI: 1.17-1.68]. Pre-pregnancy underweight was not associated with an increased risk of early miscarriage or miscarriage. We observed interactions between pre-pregnancy BMI and singleton or twin pregnancy in early miscarriage and miscarriage (P = 0.017 and P = 0.003, respectively). Twin pregnancy increased the effects of pre-pregnancy BMI on early miscarriage and miscarriage (early miscarriage: a. singleton pregnancy: RR = 1.02, 95% CI: 1.01-1.04; b. twin pregnancy: RR = 1.08, 95% CI: 1.03-1.13; miscarriage: a. singleton pregnancy: RR = 1.02, 95% CI: 1.01-1.04; b. twin pregnancy: RR = 1.08, 95% CI: 1.05-1.13). CONCLUSIONS Pre-pregnancy obesity was associated with higher risks of early miscarriage and miscarriage in the ART population, and twin pregnancy increased the effects of pre-pregnancy BMI on early miscarriage and miscarriage. Women should maintain a normal BMI before ART initiation to prevent adverse pregnancy outcomes.

Maternal B-vitamin intake and B-vitamin supplementation during pregnancy in relation to neonatal congenital heart defects: a case-control study with propensity score matching. Eur J Clin Nutr 2020; 75:782-791. [PMID: 33199851 DOI: 10.1038/s41430-020-00804-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 10/09/2020] [Accepted: 10/31/2020] [Indexed: 11/10/2022]
Abstract
BACKGROUND/OBJECTIVES The effect of dietary folate intake or folic acid (FA) supplementation during pregnancy on neonatal congenital heart defects (CHDs) remains inconclusive. There are limited data about non-folate-B-vitamin intake and the risk of CHDs. Furthermore, few studies have investigated dietary B-vitamin intake and B-vitamin supplement use simultaneously in relation to the risk of CHDs. This study aimed to explore the associations between maternal folate, vitamin B6, and vitamin B12 intake (dietary intake, total intake from diet and supplements); B-vitamin supplement use during pregnancy; and the risk of CHDs using the propensity score matching (PSM) method. METHODS We conducted a case-control study and included 760 cases and 1600 controls in Shaanxi Province, China. Diet, supplement use and other information were collected through a questionnaire interview. By using the 1:2 ratio PSM method, 396 cases were matched with 792 controls. Conditional logistic regression was used to investigate the associations between maternal B-vitamin intake and supplement use during pregnancy and CHDs. RESULTS Higher maternal dietary and total intake of folate and vitamin B12 were associated with reduced risk of CHDs, and the tests for linear trend were significant. Compared with non-users, maternal FA + VB6 + VB12 containing supplement use during pregnancy (OR 0.61, 95%CI 0.40-0.94), FA supplement use during pregnancy (OR 0.70, 95%CI 0.50-0.98) and in the first trimester (OR 0.62, 95%CI 0.46-0.85) were associated with a lower risk of CHDs. CONCLUSIONS The findings of this study suggest that a higher intake of folate and vitamin B12 during pregnancy reduces the risk of CHDs.

Abstract
BACKGROUND/OBJECTIVES Preterm birth is a global public health priority related to maternal nutrition. The effect of maternal calcium intake during pregnancy on preterm birth is inconclusive and data is lacking in China. We aimed to estimate the role of calcium intake from diet and supplements on preterm birth in the Chinese population. METHODS We used data of 7195 women from a large-scale cross-sectional study in Northwest China. Dietary intake was evaluated via a validated food frequency questionnaire, and other information was collected by a structured questionnaire. Generalized estimating equation models were used to estimate the relationship between calcium intake and preterm birth. RESULTS Inadequate dietary calcium intake was universal in our population (85.9%), and no association was found between daily dietary calcium intake and preterm birth. Maternal calcium supplementation was significantly associated with reduced risk of preterm birth (OR 0.72, 95% CI 0.60, 0.87, P = 0.001), particularly among women who commenced calcium supplementation in the second and third trimester of pregnancy with longer duration (OR 0.62, 95% CI 0.42, 0.91, P = 0.015). Higher daily calcium intake from supplements was linked with lower preterm birth risk (every 100 mg increase: OR 0.87, 95% CI 0.79, 0.96, P = 0.004). There is a negative association between daily total calcium intake and preterm birth among calcium supplement users (every 100 mg increase: OR 0.91, 95% CI 0.84, 0.97, P = 0.007). CONCLUSIONS In conclusion, appropriate calcium supplementation during pregnancy could be beneficial in the prevention of preterm birth, and it might be suitable for implementing in low calcium intake areas of China.

Abstract
OBJECTIVE To explore the relationship between parity and macrosomia and provide the necessary reference for the maternal and children health service. METHOD A cross-sectional epidemiological survey with the purpose to assess the birth outcomes was conducted in Shaanxi province, China. RESULTS The incidence of macrosomia in multiparas was higher than that in primiparas. Univariate analysis showed that maternal age < 25 years, peasant/housework, living in rural areas and female infants were the protective factors of macrosomia. The possibility of having a macrosomic infant also increased with gestational age, maternal education level, household wealth index, living in Central Shaanxi and gestational diabetes. The generalized linear mixed models represented the association between parity and macrosomia. After adjusting for statistically significant factors in univariate analysis from model 1 to model 3, the risk of being born macrosomia was 1.26 times higher for a multipara compared to that for a primipara. CONCLUSIONS Present study indicated parity of two children was associated with increased risk for macrosomic births compared with parity of one child. Compared to primiparas, multiparas should far strengthen the pre-pregnancy education and the guidance during pregnancy to control pre-pregnancy body mass index and pregnancy weight, and keep the appropriate exercise and balanced diet.

Abstract
BACKGROUND AND OBJECTIVES Few studies have described the socioeconomic disparity of dietary quality in Northwest China. The present study aimed to evaluate the diet quality of pregnant women in Shaanxi province of Northwest China by using the Diet Balance Index for Pregnancy (DBI-P) and explored the relationships with socioeconomic status (SES). METHODS AND STUDY DESIGN A cross-sectional analysis of data from 7,630 women who were pregnant during 2012-2013 was performed. Dietary intake during the whole pregnancy was assessed by FFQ within 12 months (median, 3 months; 10th-90th percentile, 0-7 months) after delivery. Diet quality evaluated by the DBI-P was related to socioeconomic factors. RESULTS Most women had insufficient consumption of vegetables (72.27%), dairy (89.58%), meat (82.07%), fish and shrimp (92.23%), eggs (62.54%), and dietary variety (97.92%). 67.76% of women had excessive intake of grains, and 87.77% and 69.79% of participants had surplus consumption of edible oil and salt respectively. Women with higher education, occupation and household wealth index (HWI) consumed more vegetables, fruit, dairy, soybean and nuts, meat, fish and shrimp, eggs, edible oil, alcohol and dietary variety but less grains and salt. After adjusting for confounders, education, occupation and HWI were negatively associated with the level of inadequate dietary intake. Conversely, individuals with medium HWI had higher level of excessive dietary intake compared to low HWI groups. CONCLUSIONS The diet quality of pregnant women in Northwest China was associated with SES. Socioeconomic disparities in diet quality should be considered when planning nutrition interventions for pregnant women.

Abstract
Objective: To demonstrate the association between pre-pregnancy maternal overweight, obesity, and perinatal outcomes of singletons conceived by assisted reproductive technology (ART). Design: Retrospective cohort study from 2006 to 2015 data from a single ART center. Setting: Assisted Reproduction Center, Northwest Women's and Children's Hospital, Xi'an, Northwestern China. Patients: We included 7,818 women undergoing ART and their singleton infants. Interventions: None. Main Outcome Measure: The primary outcome measures were preterm birth (PTB), macrosomia, low birth weight, small for gestational age, and large for gestational age (LGA). Results: We experienced an increase in the risk of PTB, macrosomia, and LGA in overweight and obese groups compared with that in normal-weight groups [PTB: overweight vs. normal weight: odds ratio [OR] = 1.44, 95% CI: 1.18-1.75; obesity vs. normal weight: OR = 1.53, 95% CI: 1.04-2.25; macrosomia: overweight vs. normal weight: OR = 1.78, 95% CI: 1.48-2.14; obesity vs. normal weight: OR = 2.16, 95% CI: 1.52-3.06; LGA: overweight vs. normal weight: OR = 1.63, 95% CI: 1.39-1.90; obesity vs. normal weight: OR = 2.11, 95% CI: 1.57-2.83]. We observed a significant interaction between maternal BMI and fresh/frozen embryo transfer on PTB and LGA (P = 0.030; P = 0.030). Fresh embryo transfer significantly increased the effect of maternal BMI on LGA (fresh: OR = 1.14, 95% CI: 1.10-1.18; frozen: OR = 1.09, 95% CI: 1.04-1.13), and frozen embryo transfer increased the effect of maternal BMI on PTB (fresh: OR = 1.03, 95% CI: 0.99-1.08; frozen: OR = 1.09, 95% CI: 1.04-1.15). Conclusions: Pre-pregnancy maternal overweight and obesity were associated with higher risks of PTB, macrosomia, and LGA in ART-conceived singletons. These associations were affected by the timing of embryo transfer (fresh/frozen embryo transfer). Therefore, we recommend women before ART to maintain a normal BMI for the prevention of adverse perinatal outcomes.

Abstract
PURPOSE The ectopic pregnancy (EP) rate after in vitro fertilization-embryo transfer (IVF-ET) is higher than after spontaneous conception. The reason for the increased risk of EP is not clear. We aimed to determine the risk factors associated with EP in patients undergoing IVF-ET. METHODS This was a 1:4 matched case-control study that enrolled 225 EP patients and 900 matched intrauterine pregnancy patients from the ART center of Northwest Women's and Children's Hospital from January 2014 to April 2018. Conditional logistic regression was used to analyze the association between risk factors and EP, and a receiver-operating characteristic (ROC) curve was generated for the predictors of EP. RESULTS Our findings showed that tubal factor (OR 1.61; 95% CI 1.12-2.31) and pelvic surgery other than cesarean section (OR 2.04; 95% CI 1.26-3.29) were associated with a higher risk of EP (p = 0.001). An endometrial thickness > 12 mm prior to embryo transfer (OR 0.27; 95% CI 0.13-0.56) and the number of transferable embryos (OR 0.71; 95% CI 0.65-0.78) were protective factors against EP (p < 0.001). The other factors did not have a significant effect on the probability of developing ectopic pregnancy. The area under the curve of the endometrial thickness and the number of transferable embryos for EP prediction were higher than those for tubal factor and pelvic surgery other than cesarean section. CONCLUSIONS An endometrial thickness > 12 mm is a strong protective factor against ectopic pregnancy. Attention should be paid to women with specific characteristics who have undergone IVF-ET.

Abstract
OBJECTIVE To investigate the effects of an inhibitor of NF-κB, PDTC (pyrrolidine dithiocarbamate), on TLR4 (Toll-like receptor 4) expression in the left ventricle of Goldblatt hypertension rats. MATERIALS AND AND METHODS Goldblatt rat model of two-kidney, one-clip (2K1C) hypertension was established in 70 healthy male rats. The rats were randomly divided into sham operation group (S group, n=20), non-drug intervention hypertension group (H group, n=25), and PDTC intervention group (P group, n=25). P group was injected with PDTC. The clip was inserted in the left renal artery of H group and P group (2K1C). Eight weeks after the operation, the rats were sacrificed and the samples of the left ventricle were collected. The concentration of AngII in the left ventricle was assessed by radioimmunoassay. RT-PCR was used to examine the mRNA expression of TLR4 in the left ventricle. Immunohistochemistry was adopted to examine the location of TLR4 and NF-κB in the myocardium. Victoria blue-Ponceau staining of Cardiac collagen was used to evaluate the degree of myocardial fibrosis. RESULTS Eight weeks after the operation, caudal SBP, meridional end-systolic stress, left ventricular mass index, relative wall thickness, cardiac fibrosis degree, and the concentration of AngII in the left ventricle in P group were significantly lower than those in H group (p<0.01). In cardiac myocytes of S group and P group, TLR4 expression was diffused and presumably cytoplasmic. TLR4 mRNA expression in P group was significantly lower than that of H group (p<0.01). CONCLUSIONS PDTC not only inhibited the activation of NF-κB, but decreased TLR4 expression and AngII content, indicating that the inflammatory signals and oxidative stress mediated by TLR4/NF-κB are involved in the occurrence and development of left ventricular remodeling. Intervention with TLR4/NF-κB and anti-inflammatory and anti-oxidative therapy may be a new target to reverse left ventricular remodeling.

Abstract
BACKGROUND AND OBJECTIVES The results of prenatal nutrient supplementation on birth weight are inconsistent in different areas. This study aimed to investigate whether the effects of prenatal iron plus folic acid and folic acid supplementation on neonatal birth weights differed between urban and rural areas of Northwest China. METHODS AND STUDY DESIGN A stratified multistage random sampling method was used to recruit women between the ages of 15 and 49 and their offspring born between 2010 and 2013 from 10 urban areas and 20 rural areas of the Shaanxi Province of Northwest China. Information regarding socio-demographics and prenatal nutrient supplementation status was collected using a standardized questionnaire, and the neonatal birth weights were obtained from the birth certificates. Multilevel models were established separately for the urban and rural areas to assess the effects of prenatal nutrient supplementation on neonatal birth weights. RESULTS The association between prenatal nutrient supplementation and neonatal birth weight was not statistically significant in urban areas. However, in rural areas, prenatal iron plus folic acid and folic acid supplementation increased the mean birth weights by 45.3 g (9.4 to 81.1 g, p=0.014) and 30.9 g (15.6 to 46.1 g, p<0.001), respectively. CONCLUSIONS The effects of prenatal nutrient supplementation on neonatal birth weights differ between urban and rural areas of Northwest China. The different effects may be due to the different nutritional status of the urban and rural pregnant women. Prenatal nutrient supplementation may be a helpful way for improving neonatal birth weight in rural areas.

Abstract
OBJECTIVES To report the situation of maternal micronutrient supplementation before and during pregnancy in Northwest China and to examine the rates of and factors related to the adherence to micronutrient supplementation among pregnant women in this region, where dietary micronutrient intake is commonly insufficient. DESIGN A large-scale population-based cross-sectional survey. SETTING Twenty counties and ten districts of Shaanxi Province. PARTICIPANTS A sample of 30 027 women were selected using a stratified multistage random sampling method. A total of 28 678 women were chosen for the final analysis after excluding those who did not provide clear information about nutritional supplementation before and during pregnancy. MAIN OUTCOME MEASURES Maternal adherence to micronutrient supplementation (high and low) were the outcomes. They were determined by the start time and duration of use according to Chinese guidelines (for folic acid (FA) supplements) and WHO recommendations (for iron, calcium and multiple-micronutrient (MMN) supplements). RESULTS In total, 83.9% of women took at least one kind of micronutrient supplement before or during pregnancy. FA (67.6%) and calcium (57.5%) were the primarily used micronutrient supplements; few participants used MMN (14.0%) or iron (5.4%). Adherence to supplementation of all micronutrients was low (7.4% for FA, 0.6% for iron, 11.7% for calcium and 2.7% for MMN). Higher educational levels, higher income levels, urban residence and better antenatal care (including pregnancy consultation and a higher frequency of antenatal visits) were associated with high adherence to micronutrient supplementation. CONCLUSION Maternal micronutrient supplementation before and during pregnancy in Northwest China was way below standards recommended by the Chinese guidelines or WHO. Targeted health education and future nutritional guidelines are suggested to improve this situation, especially in pregnant women with disadvantaged sociodemographic conditions.
