Pregnancy is a controlled state of inflammation. Deregulation of cytokine networks can lead to adverse pregnancy outcomes including preeclampsia (PE). We aimed to identify single nucleotide polymorphisms in immunoregulatory genes that signify an increased risk of the gestational hypertensive disorders PE and gestational hypertension (GH). 1169 nulliparous pregnant women and their partners were recruited prospectively for the Adelaide SCOPE study. PE and GH were classified using strict guidelines. Uncomplicated pregnancies served as controls. Peripheral blood from couples and cord blood from neonates were collected. DNA was extracted and genotyped for Interleukin (IL)-6 rs1800795, IL-4 rs2243250, IL-10 rs1800896 and rs1800871, mannose binding lectin (MBL) rs1800450, transforming growth factor beta 1 (TGFβ-1) rs1800469 and cyclooxygenase (COX)-2 rs20417 & rs5275 and inducible nitric oxide synthase (NOS2A) rs1137933 using the Sequenom MassARRAY system. Genotypes for Caucasian PE (n = 75) and GH (n = 102) were compared with controls (n = 422) and analysed using Chi-Square. In neonates IL-6 G allele carriage was associated with PE (P = 0.011, OR=2.0, 95% CI = 1.2–3.7) and the CC genotype associated with GH (P = 0.002). Neonatal IL-10 RS180071 AA genotype associated with PE (P = 0.041) and IL-10 RS1800896 AA associated with GH (P = 0.022). Paternal NOS2A C allele was more frequent in PE (P = 0.03, OR = 2.1, 95% CI = 1.1–4.5), and maternal NOS2A CC more frequent in GH (P = 0.018). Increased neonatal carriage of MBL rs1800450 AA+GA genotypes associated with GH (P = 0.03, OR = 2.2, 95% CI = 1.1–4.5). No associations were observed between TGFβ-1 or COX2 genotypes and PE or GH. Associations between neonatal IL-6 G, which confers high placental IL-6 expression, and PE suggest a possible mechanism by which PE is a pro-inflammatory exacerbation of placental origin. Since placental IL-10 is important for maternal tolerance of the fetus, genotypes predisposing to low IL-10 expression in the neonate which associate with both PE and GH, suggest a role for decreased placental IL-10 in these disorders.

Background. The presence of a capsule is an important prognostic factor in hepatocellular carcinoma (HCC). Capsule formation is affected by tumor-host interaction, which may include collagen deposition and extracellular matrix (ECM) degradation. Purpose. This study aimed to examine whether single-nucleotide polymorphisms (SNPs) in the genes for COL1A1 MUC15, MMP14, CD97, SMYD3, BRAF, and transforming growth factor beta 1 (TGF-β) are related to capsule formation. Methods. We prospectively recruited and analyzed 185 patients with HCC with or without a capsule between 2019 and 2020. The SNPs involved were analyzed by polymerase chain reaction. Differences in the allele and genotype frequency between the cases and controls were evaluated using the chi-square test. Odds ratios and 95% confidence intervals were calculated by logistic regression analysis with adjustment for age and sex. Stratification analyses were also performed with preselected variables. Results. The single-locus analysis showed that the presence of a capsule was significantly associated with five SNPs : MUC15 rs17309195 P = 0.01 , rs12271124 P =   0.02 , rs10430847 P = 0.04 , MMP14 rs17884816 P = 0.01 , and BRAF rs74512895 P = 0.03 . Adjusted logistic regression revealed that the decreased capsule formation was statistically significantly associated with BRAF rs76603725, COL1A1 rs2269336, and MUC15 rs17309195, while MMP14 rs17884816 and MUC15 rs10430847, rs2063278, and rs967490 were associated with increased capsule formation. The MUC15 block 2 haplotype was associated with increased capsule formation. Conclusions. MUC15, MMP14, BRAF, and COL1A1 gene polymorphisms are associated with capsule formation in HCC. Studies involving larger samples are needed to confirm our results.

Introduction It is not yet fully known whether hypertensive disorders (HTD) during pregnancy impose an increased risk of development of bronchopulmonary dysplasia (BPD) in preterm newborn infants. Objective To test the hypothesis that preeclampsia and other HTD are associated with the development of BPD in preterm infants. Materials and Methods Data on mothers and preterm infants with gestational age 24 to 30 weeks were prospectively analyzed in 11 Portuguese level III centers. Statistical analysis was performed using IBM SPSS statistics 23. Results A total of 494 preterm infants from 410 mothers were enrolled, and 119 (28%) of the 425 babies, still alive at 36 weeks, developed BPD. The association between chronic arterial hypertension, chronic arterial hypertension with superimposed preeclampsia, and gestational hypertension in mothers and BPD in preterm infants was not significant (p = 0.115; p = 0.248; p = 0.060, respectively). The association between preeclampsia–eclampsia and BPD was significant (p = 0.007). The multivariate analysis revealed an association between preeclampsia–eclampsia and BPD (odds ratio [OR] = 4.6; 95% confidence interval [CI] 1.529–13.819; p = 0.007) and a protective effect for BPD when preeclampsia occurred superimposed on chronic arterial hypertension in mothers (OR = 0.077; 95%CI 0.009–0.632; p = 0.017). Conclusion The results of this study support the association of preeclampsia in mothers with BPD in preterm babies and suggest that chronic hypertension may be protective for preterm babies.

Introduction: The Coronary Artery Risk Detection in Appalachian Communities (CARDIAC) Project has screened West Virginia 5th graders since 1998 to facilitate primordial prevention of coronary heart disease (CHD) in WV. LDL-c levels above 175 mg/dl in children suggest Familial Hyperlipidemia (FH) in the child’s family and a level above 160 mg/dl with history of CHD in relatives can also establish a diagnosis. Hypothesis: Based on previous adult literature, the association of lower height with higher LDL level observed in adults begins in childhood and is prominent in children with LDL in FH range. Methods: Fifth graders are screened yearly in WV schools with parental consent for Body Mass Index and lipid panel. Lipids were analyzed with respect to either short stature < 2 SD for height or comparing 1st (shortest) and 4th quartiles of the population. Statistical analysis for age- and gender-adjusted height percentiles was performed in SAS. Results: 59,386 children had lipid and height data. Mean LDL-c for 1st vs. 4th quartile of height was 94.08 mg/dl (95% Confidence Interval-CI 93.66-94.51) vs. 90.03 mg/dl (CI 89.65-90.42). First quartile of height students had average 4.05 mg/dl higher LDL-c (95% CI 3.48 -4.62 mg/dl). 4398 children had an LDL level above 130 g/dl, 632 above 160 mg/dl and 247 above 175 mg/dl. The Chi square analysis of short stature (height 130 g/dl was also significant (p=0.013) with increased odds of LDL-c above 130 g/dl compared to non-short stature (OR= 1.37, CL 1.07-1.75). Table 1 shows odds ratio for varying levels of elevated LDL-c for the first (shortest) vs. 4th (tallest) quartile of students. Conclusions: Shorter stature is associated with higher LDL-c level in WV 5th graders generally and in those children with increased risk for genetic dyslipidemia. The trend to increasing odds ratio in strata of higher LDL-c supports a recent report of association of single nucleotide polymorphisms selecting for lower genetic height and higher LDL-c.

Abstract Objective To test the hypothesis that high fetal fraction (FF) on first trimester cell-free deoxyribonucleic acid (cfDNA) aneuploidy screening is associated with adverse perinatal outcomes. Study Design This is a single-institution retrospective cohort study of women who underwent cfDNA screening at <14 weeks' gestation and delivered a singleton infant between July 2016 and June 2018. Women with abnormal results were excluded. Women with high FF (≥95th percentile) were compared with women with normal FF (5th–95th percentiles). Outcomes investigated were preterm birth, small for gestational age, and hypertensive disorders of pregnancy. Results A total of 2,033 women met inclusion criteria. The mean FF was 10.0%, and FF >16.5% was considered high (n = 102). Women with high FF had a greater chance of delivering a small for gestational age infant <fifth percentile, with an adjusted odds ratio of 2.4 (95% confidence interval: 1.1–4.8, p = 0.039). There was no significant association between high FF and either preterm birth or hypertensive disorders of pregnancy. Conclusion Women with a high FF in the first trimester are at increased risk of delivering a small for gestational age infant <fifth percentile. Further investigation into the clinical implications of a high FF is warranted.

Aberrant function of Smad2, a crucial member of transforming growth factor beta (TGF-β) signaling, is associated with the development of malignancies, particularly in the gastrointestinal district. However, little is known about its possible prognostic role in such tumor types. With the first meta-analysis on this topic, we demonstrated that the lack of the activated form of Smad2 (phosphor-Smad2 or pSmad2), which was meant to be the C-terminally phosphorylated form, showed a statistically significant association with an increased risk of all-cause mortality in patients with gastrointestinal cancers (RR, 1.58; 95% CI, 1.05–2.37, p = 0.029, I2 = 84%), also after having adjusted for potential confounders (RR, 1.65; 95% CI, 1.24–2.18; p < 0.001; I2 = 4%). This finding highlights the importance of the TGF-β signaling in this type of cancer. In this line, further studies are needed to explore more in depth this important molecular pathway, focusing also on potential therapeutic strategies based on its effectors or molecular targets.

Background:Transforming growth factor beta1 (TGFβ1) is a multifunctional cytokine involved in inflammation and pathogenesis of atherosclerosis. The aim of the present study was to investigate the relationship between human TGFβ1 gene +869T>C (rs1800470), -509C>T (rs1800469) single nucleotide polymorphisms (SNPs) and haplotypes and cerebral infarction (CI) in a Chinese population.Methods:The genetic association study was performed in 450 Chinese patients (306 male and 144 female) with CI and 450 control subjects (326 male and 124 female). TGFβ1 gene +869T>C and -509C>T polymorphisms were identified with amplification refractory mutation system polymerase chain reaction and DNA sequencing method.Results:The individual SNPs analysis showed the +869T and -509C in an additive model (+869T vs +869C; -509 C vs T), +869TT genotype in a recessive model (TT vs TC+CC) and 509CC genotype in a dominant model (CC+ CT vs TT) were identified to be related to CI (P<0.05). +869T>C and -509C>T SNPs were in strong linkage disequilibrium (d'=0.87, R2=0.75). Haplotype analysis showed that +869C/-509T haplotype was associated with a significant decreased risk of CI (OR= 0.86, 95%CI, 0.70-0.92; P=0.007). Furthermore,+869T/-509C haplotype was associated with a significant increased risk of CI (OR=1.31, 95%CI, 1.10-2.03; P=0.019).Conclusions:The results of this study indicate that polymorphisms and the haplotypes in the TGFβ1 gene might be genetic markers for CI in the Chinese population.

Major depressive disorder (MDD) compromises the individual’s capacity for self-care and productivity. Single nucleotide polymorphisms (SNP) of a number of genes have been associated with MDD. The zinc transporter-3 protein, encoded by the ZnT3 (SLC30A3) gene, maintains zinc-glutamate homeostasis at the glutamatergic synapse, a disruption of which increases risk of MDD. We hypothesise that variation in SLC30A3 (rs11126936) SNP increases risk of MDD. We recruited 300 MDD cases and 300 controls, matched in the ratio of 1:1 by age, gender and ethnicity. PCR-restriction fragment length polymorphism analysis was used in DNA genotyping, validated by sequencing 10% of samples. Deviation from the Hardy-Weinberg equilibrium was tested using the chi-square test. Conditional logistic regression was used to estimate adjusted odds ratios, controlling for age, gender, ethnicity, occupation and family monthly income. Genotypes G/G and G/T showed two times greater odds of developing MDD compared to variant genotype T/T (OR=1.983, 95% CI=1.031-3.815; p=0.040 and OR=2.232, 95% CI=1.100-4.533; p=0.026 respectively). Carriers of genotypes G/G and G/T of the SNP rs11126936 in SLC30A3 are associated with increased risk of MDD.

Determinants of pregnancy hypertensive disorders in Indonesia PurposeThis study aimed to assess the determinant factors of gestational hypertension (HDP) in Indonesia.MethodsThis research was an observational analytic study using a cross-sectional design. Sampling was calculated using consecutive sampling technique. The subjects were all pregnant women aged 15-54 years old in 33 provinces in Indonesia and 9024 women were selected as subjects. Chi-square and binomial regression tests were used to analyze the determinants of HDP to see the value of the Ratio Prevalence (RP). ResultsThe prevalence of hypertension among pregnant women was 6.18% (558 people) after being adjusted with external variables which were potentially confounders. The highest of hypertension was found in West Java with 59 pregnant women (10.57%). Overweight and chronic hypertension were related to hypertensive disorders in pregnancy with RP: 2.13 (95% CI: 1.80-2.51); and in overweight with RP: 4.36 (95% CI: 3.6-5.26) in hypertension assessments. The use of contraceptives was not a risk factor for hypertensive disorders in Indonesia with RP 0.92 (95% CI: 0.76-1.10). ConclusionOverweight and chronic hypertension are risk factors for the incidence of hypertensive disorders in pregnancy in Indonesia.

Background Studies have reported an increased risk of adverse pregnancy outcome associated with pre-pregnancy body mass index (BMI). However, the data on such associations in urban areas of southern Chinese women is limited, which drive us to clarify the associations of pre-pregnancy BMI and the risks of adverse pregnancy outcomes (preterm birth (PTB) and low birth weight (LBW)) and maternal health outcomes (gestational hypertension and cesarean delivery). Methods We performed a hospital-based case-control study including 3,864 Southern Chinese women who gave first birth to a live singleton infant from January 2015 to December 2015. PTB was stratified into three subgroups according to gestational age (extremely PTB, very PTB and moderate PTB). Besides, we combined birth weight and gestational age to dichotomise as being small for gestational age (SGA, less than the tenth percentile of weight for gestation) and non-small for gestational age (NSGA, large than the tenth percentile of weight for gestation), gestational week was also classified into categories of term, 34-36 week and below 34 week.. We then divided newborns into six groups: (1) term and NSGA; (2) 34–36 week gestation and NSGA; (3) below 34 week gestation and NSGA; (4) term and SAG; (5) 34–36 week gestation and SAG; (6) below 34 week gestation and SAG. Adjusted logistic regression models was used to estimate the odds ratios of adverse outcomes. Results Underweight women were more likely to give LBW (AOR = 1.44, 95% CI [1.11–1.89]), the similar result was seen in term and SAG as compared with term and NSAG (AOR = 1.78, 95% CI [1.45–2.17]), whereas underweight was significantly associated with a lower risk of gestational hypertension (AOR = 0.45, 95% CI [0.25–0.82) and caesarean delivery (AOR = 0.74, 95% CI [0.62–0.90]). The risk of extremely PTB is relatively higher among overweight and obese mothers in a subgroup analysis of PTB (AOR = 8.12, 95% CI [1.11–59.44]; AOR = 15.06, 95% CI [1.32–172.13], respectively). Both maternal overweight and obesity were associated with a greater risk of gestational hypertension (AOR = 1.71, 95% CI [1.06–2.77]; AOR = 5.54, 95% CI [3.02–10.17], respectively) and caesarean delivery (AOR = 1.91, 95% CI [1.53–2.38]; AOR = 1.85, 95% CI [1.21–2.82], respectively). Conclusions Our study suggested that maternal overweight and obesity were associated with a significantly higher risk of gestational hypertension, caesarean delivery and extremely PTB. Underweight was correlated with an increased risk of LBW and conferred a protective effect regarding the risk for gestational hypertension and caesarean delivery for the first-time mothers among Southern Chinese.

Abstract Background Hypertensive disorders of pregnancy (HDP) affect 5–10% of pregnant women. Women after HDP have 2–3 times increased risk of heart attack, stroke and diabetes, as soon as 5–10 years after pregnancy. Australian healthcare providers’ knowledge of cardiovascular disease (CVD) risks for women after HDP is unknown, and this study aimed to explore their current knowledge and practice regarding long-term cardiovascular health after HDP, as a precursor to producing targeted healthcare provider education on health after HDP. Methods A custom-created, face-validated online survey explored knowledge about long-term risks after HDP. Distribution occurred from February to July 2019 via professional colleges, key organisations and social media. The objective was to assess current knowledge and knowledge gaps amongst a group of healthcare providers (HCP) in Australia, regarding long-term cardiovascular health after hypertensive disorders of pregnancy (HDP), specifically gestational hypertension or preeclampsia. Results Of 492 respondents, 203 were midwives, 188 obstetricians, 75 general practitioners (GP), and 26 cardiologists. A risk knowledge score was computed with 0–6 considered low, 6.1–8.9 moderate and 9–12 high. Most participants (85%) were aware of increased cardiovascular disease after preeclampsia and gestational hypertension (range 76% midwives to 100% cardiologists). There were significant differences in average knowledge scores regarding health after preeclampsia; high for cardiologists (9.3), moderate for GPs and obstetricians (8.2 and 7.6 respectively) and low for midwives (5.9). Average knowledge scores were somewhat lower for gestational hypertension (9.0 for cardiologists, 7.4 for obstetricians and GPs, 5.1 for midwives). Knowledge was highest regarding risk of chronic hypertension, moderate to high regarding risk of ischaemic heart disease, stroke and recurring HDP, and low for diabetes and peripheral vascular disease. Only 34% were aware that risks start < 10 years after the affected pregnancy. Conclusion(s) Participants were aware there is increased cardiovascular risk after HDP, although less aware of risks after gestational hypertension and some specific risks including diabetes. Findings will inform the development of targeted education.
