Abstract
During pregnancy there is a physiological increase in total cholesterol (TC) and triglycerides (TG) plasma concentrations, due to increased insulin resistance, oestrogens, progesterone, and placental lactogen, although their reference values are not exactly known, TG levels can increase up to 300mg/dL, and TC can go as high as 350mg/dL. When the cholesterol concentration exceeds the 95th percentile (familial hypercholesterolaemia (FH) and transient maternal hypercholesterolaemia), there is a predisposition to oxidative stress in foetal vessels, exposing the newborn to a greater fatty streaks formation and a higher risk of atherosclerosis. However, the current treatment of pregnant women with hyperlipidaemia consists of a diet and suspension of lipid-lowering drugs. The most prevalent maternal hypertriglyceridaemia (HTG) is due to secondary causes, like diabetes, obesity, drugs, etc. The case of severe HTG due to genetic causes is less prevalent, and can be a higher risk of maternal-foetal complications, such as, acute pancreatitis (AP), pre-eclampsia, preterm labour, and gestational diabetes. Severe HTG-AP is a rare but potentially lethal pregnancy complication, for the mother and the foetus, usually occurs during the third trimester or in the immediate postpartum period, and there are no specific protocols for its diagnosis and treatment. In conclusion, it is crucial that dyslipidaemia during pregnancy must be carefully evaluated, not just because of the acute complications, but also because of the future cardiovascular morbidity and mortality of the newborn child. That is why the establishment of consensus protocols or guidelines is essential for its management.

Abstract
Thyroid function is central in the control of physiological and pathophysiological processes. Studies in animal models and human research have determined that thyroid hormones modulate cellular processes relevant for aging and for the majority of age‐related diseases. While several studies have associated mild reductions on thyroid hormone function with exceptional longevity in animals and humans, alterations in thyroid hormones are serious medical conditions associated with unhealthy aging and premature death. Moreover, both hyperthyroidism and hypothyroidism have been associated with the development of certain types of diabetes and cancers, indicating a great complexity of the molecular mechanisms controlled by thyroid hormones. In this review, we describe the latest findings in thyroid hormone research in the field of aging, diabetes, and cancer, with a special focus on hepatocellular carcinomas. While aging studies indicate that the direct modulation of thyroid hormones is not a viable strategy to promote healthy aging or longevity and the development of thyromimetics is challenging due to inefficacy and potential toxicity, we argue that interventions based on the use of modulators of thyroid hormone function might provide therapeutic benefit in certain types of diabetes and cancers.

Abstract
BACKGROUND It is unknown to what extent higher maternal blood pressure (BP) in early postpartum impacts the relationship between higher maternal weight status and greater infant weight gain in early postpartum. OBJECTIVE To evaluate the mediating role of higher maternal BP at 1 month postpartum on the association between higher maternal weight status at 1 month postpartum and greater infant weight gain over 6 months postpartum. METHODS Participants were 169 Hispanic mother-infant pairs. Maternal body mass index (BMI) and BP were assessed at 1 month postpartum. Infant weight was measured at 1 and 6 months postpartum to calculate weight-for-age z scores (WAZ). Multiple linear regression models were used for prediction, and Sobel test was used to determine mediation. RESULTS Controlling for maternal pre-pregnancy BMI, age, delivery mode, infant sex, and infant birth weight revealed that both maternal BMI (β = .29) and BP (β = .32) predicted infant WAZ gain (both P ≤ .03). However, the relationship between infant WAZ gain and maternal BMI was no longer significant after further adjustment for maternal BP, which remained significant (P < .05). Maternal BP explained 23.6% (Sobel T = 2.01) of the association between maternal BMI at 1 month and infant WAZ gain over 6 months. CONCLUSION Our data suggest that higher maternal weight status at 1 month postpartum is related to greater infant weight gain over 6 months postpartum, and this relationship is mediated by higher maternal BP at 1 month postpartum.

Abstract
For the effective management and screening of patients with diabetes, lipid profile has been a useful mean. Here, we hypothesized that biochemical analyses of blood serum in pregnant women with GDM will develop an insight on the pathogenesis of the disease and possibly uncover new biomarkers. In order to test our hypothesis, antenatal pregnant women (n = 300) were selected for blood samples including 176 with positive clinical/family history and 124 with negative clinical/family history of GDM during the early second trimester (14-18 weeks of gestation). All the subjects were followed up to the early third trimester (24-28 weeks of gestation) for second sampling until the onset of GDM. Lipid profile data shows that mean values of triglycerides, total cholesterol, low density lipids and very low density lipids were significantly higher (p < 0.05) and mean HDL was significantly lower in early second trimester in those patients who subsequently developed GDM during late third trimester when compared with those who didn't develop GDM. Inflammatory biomarker such as High-sensitivity C-reactive protein (hs-CRP) levels were also found to be significantly higher by 69% increase in patients who developed GDM later in third trimester in comparison with those who didn't develop. About 32% patients who finally developed GDM belonged to positive clinical/family history group. The results of our study indicate that abnormal serum cholesterol; triglycerides, HDL, LDL, VLDL and hs-CRP play a vital in pathophysiology of gestational diabetes. Early diagnosis of GDM based on these biochemical markers will help decrease adverse neonatal and maternal outcomes.

Good glycemic control of gestational diabetes mellitus is associated with the attenuation of future maternal cardiovascular risk: a retrospective cohort study. Cardiovasc Diabetol 2019; 18:75.

Abstract
BACKGROUND To examine whether glycemic control of gestational diabetes mellitus (GDM) could modify the risk for future maternal metabolic and cardiovascular morbidities. METHODS A retrospective cohort study of women with a first diagnosis of GDM who delivered between 1991 and 2011. Women were divided into groups of good and poor glycemic control, defined as a mean daily glucose of up to 95 mg/dL (N = 230) and more than 95 mg/dL (N = 216), respectively. In addition, a control group of women without GDM (N = 352) was also analyzed. The primary outcomes were the development of type 2 diabetes mellitus (T2DM), obesity, hypertension, or dyslipidemia. RESULTS Mean follow-up time was 15.8 ± 5.1 years. Assessment was performed at a maternal age of 45 ± 7 years. The rates of the study outcomes in the control, GDM with good glycemic control and GDM with poor glycemic control were as follows: T2DM [19 (5.4%), 87 (38%), 127 (57%)]; hypertension [44 (13%), 42 (18%), 44 (20%)]; obesity [111 (32%), 112 (48%), 129 (58%)]; and dyslipidemia [49 (14%), 67 (29%), 106 (48%)]. Glycemic control was an independent risk factor for T2DM in multivariate Cox regression analysis (hazard ratio (HR) for poor glycemic control vs. controls 10.7 95% CI [6.0-19.0], good glycemic control vs. control HR 6.0 [3.3-10.8], and poor glycemic control vs. good glycemic control HR 1.8 [1.3-2.4]). Glycemic control was also an independent risk factor for dyslipidemia (poor glycemic control vs. controls HR 3.7 [2.3-5.8], good glycemic control vs. controls HR 2.0 [1.2-3.2], and poor glycemic control vs. good glycemic control HR 1.8 1.8 [1.3-2.6]). The fasting glucose level during oral glucose tolerance test (OGTT) was also an independent risk factor for these complications. The interaction term between glycemic control and the fasting value of the OGTT was not statistically significant, suggesting that the effect of glycemic control on the rate of future T2DM and dyslipidemia was not modified by the baseline severity of GDM. CONCLUSION GDM and especially poor glycemic control are associated with T2DM and dyslipidemia. Strict glycemic control for reducing that risk should be evaluated in prospective trials.

Abstract
OBJECTIVE Aortic dissection is an uncommon and potentially fatal complication of pregnancy; however, the association of the number of pregnancies with the indexed and absolute size of the ascending aorta in patients without aortic aneurysm or connective tissue disorders is not well elucidated. RESEARCH DESIGN AND METHODS In this prospective observational study, women aged 18-80 years old undergoing transesophageal echocardiography in a university-affiliated echocardiography laboratory between 1 January 2015 and 1 September 2015 were enrolled. Indexed and absolute sizes of ascending aorta at the levels of annulus, root, sinotubular junction (STJ), proximal and arch were measured. Patients were grouped according to their gravida number into three classes (class I: ≤3, class II: 4-7, class III: ≥7). RESULTS Of 653 screened patients, 437 women were included (38.9% gravida class I, 44.3% gravida class II and 16.7% gravida class III). In univariate analysis, the number of pregnancies correlated with indexed diameters of the root (p < .001), STJ (p < .001) and the proximal ascending aorta (p < .001). Meanwhile, the number of pregnancies neither correlated with the annular diameter nor with the arch (p = .070 and p = .154, respectively). In multivariate analyses, the gravida class was among the independent predictors of the root size along with age, aortic insufficiency and the presence of congestive heart failure. CONCLUSION Gravida class was an independent predictor of aortic size at levels of the root, STJ and the proximal ascending aorta. The largest increase was observed at the level of the aortic root.

Abstract
BACKGROUND Pregnancy and pregnancy loss may be linked to cardiovascular disease (CVD). However, the evidence is still inconsistent, especially in East Asians, whose reproductive patterns differ importantly from those in the West. We examined the associations of pregnancy, miscarriage, induced abortion, and stillbirth with CVD incidence among Chinese women. METHODS In 2004-2008, the nationwide China Kadoorie Biobank recruited 302,669 women aged 30-79 years from ten diverse localities. During 7 years of follow-up, 43,968 incident cases of circulatory disease, 14,440 of coronary heart disease, and 19,925 of stroke (including 11,430 ischaemic and 2170 haemorrhagic strokes), were recorded among 289,573 women without prior CVD at baseline. Cox regression yielded multiple adjusted hazard ratios (HRs) for CVD risks associated with pregnancy outcomes. RESULTS Overall, 99% of women had been pregnant, and among them 10%, 53%, and 7% reported having a history of miscarriage, induced abortion, and stillbirth, respectively. Each additional pregnancy was associated with an adjusted HR of 1.03 (95% confidence interval, CI: 1.02; 1.04) for circulatory disease. A history of miscarriage, induced abortion, and stillbirth, respectively, were associated with adjusted HRs of 1.04 (1.01; 1.07), 1.04 (1.02; 1.07), and 1.07 (1.03; 1.11) for circulatory disease. The relationship was stronger with recurrent pregnancy loss; adjusted HRs for each additional loss being 1.04 (1.00; 1.09) for miscarriage, 1.02 (1.01; 1.04) for induced abortion, and 1.04 (1.00; 1.08) for stillbirth. CONCLUSIONS Among Chinese women, increases in pregnancy, and a history and recurrence of miscarriage, induced abortion, and stillbirth are each associated with a higher risk of CVD.

Abstract
Background Women's parity has been associated with risk of cardiovascular disease (CVD). It is unclear, however, whether it reflects biological effects of childbearing or uncontrolled socio-economic and lifestyle factors associated with childrearing. We assessed the association between number of children and incident CVD outcomes separately in women and men. Methods In 2004-08, the nationwide China Kadoorie Biobank recruited 0.5 million individuals aged 30-79 years from 10 diverse regions. During 7 years of follow-up, 24 432 incident cases of coronary heart disease (CHD) and 35 736 of stroke were recorded among 489 762 individuals without prior CVD. Multivariable Cox regression models were used to estimate sex-specific hazard ratios (HRs) and 95% confidence intervals (CIs) for CHD and stroke associated with number of children. Results Overall, 98% of all participants had children and the mean number of children declined progressively from four in older participants to one or two in younger participants. Compared with childless women, women with children had an increased risk of CHD, but not of stroke [HR (95% CI): 1.14 (1.00; 1.30) and 1.03 (0.92; 1.16)]. Corresponding results for men were 1.20 (1.06; 1.35) and 1.13 (1.03; 1.24), respectively. In individuals with children, there was a log-linear association between number of children and CVD outcomes; in women, each additional child was associated with adjusted HRs of 1.02 (1.01; 1.04) for CHD and 1.02 (1.01; 1.03) for stroke, similar in magnitude to that in men [1.03 (1.01; 1.04) for CHD and 1.02 (1.01; 1.03) for stroke]. Conclusion In Chinese adults, the association between the number of children and risk of CHD and stroke was similar between men and women, suggesting that factors associated with parenthood and childrearing are more likely to affect the risk of CVD outcomes than factors associated with childbearing.

Abstract
Reproductive factors have been shown to correlate with lipid metabolism. The aim of this study was to investigate the relationship between parity and serum lipid levels in community-based Chinese female adults. A total of 4,217 female participants were enrolled. Parity was recorded according to questionnaire and serum lipid profile, including triglycerides (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C), was measured. Logistic regression models were used to analyze the association of parity to serum lipid levels, while adjusting for demographics and metabolic risk factors. Parity in this population ranged from 0 to 7. After adjusting for potential confounders, it indicated that females with more than 2 parities appeared to be less likely to suffer from abnormal serum TC level compared with nulliparae (parity = 2, odds ratio (OR) = 0.457, 95% confidence interval (CI) = 0.284–0.736; parity ≥ 3, OR = 0.363, 95% CI = 0.202–0.653). These findings suggested that parity could correlate with lipid metabolism in Chinese women. Individuals with higher parity appeared to have a lower total cholesterol in blood.

Abstract
AIMS/HYPOTHESIS In women, higher parity has been associated with increased risk of diabetes later in life. It is unclear, however, whether this association is mainly due to biological effects of childbearing, or to socioeconomic and lifestyle factors associated with childrearing. We assessed the association between number of children and diabetes risk separately in women and men. METHODS Between 2004 and 2008, the nationwide China Kadoorie Biobank recruited 0.5 million individuals aged 30-79 (mean 51 years) from ten diverse regions across China. During 7 years of follow-up, 8,840 incident cases of diabetes were recorded among 463,347 participants without prior cardiovascular diseases or diabetes. Multivariable Cox regression yielded sex-specific HRs and 95% CIs for incident diabetes by number of children. RESULTS Overall, ∼98% of all participants had children. In women, there was a J-shaped association between number of children and risk of diabetes. Compared with women with one child, the adjusted HRs for diabetes were 1.39 (95% CI 1.11, 1.73) for childless women, 1.12 (95% CI 1.07, 1.18) for those with two children, 1.23 (95% CI 1.16, 1.31) for those with three children, and 1.32 (95% CI 1.21, 1.44) for those with four or more children. In men, there was a similar association with risk of diabetes; the corresponding HRs were 1.28 (95% CI 1.02, 1.60), 1.19 (95% CI 1.12, 1.26), 1.32 (95% CI 1.21, 1.44) and 1.41 (95% CI 1.24, 1.60), respectively. In both sexes, the findings were broadly similar in different population subgroups. CONCLUSIONS/INTERPRETATION The similarity between women and men in the association between number of children and risk of diabetes suggests that parenthood is most likely to affect diabetes risk through factors associated with childrearing rather than via biological effects of childbearing.

Abstract
This study was undertaken to compare amino acid concentrations in maternal and newborn infants' serum in normal pregnancy and two groups of obese women who were born themselves with normal and small for gestational age (SGA) birth weight. Maternal cholesterol, lipoproteins concentrations and maternal and infants amino acid concentrations were evaluated at the time of delivery in 28 normal pregnancies, 46 obese pregnant women with normal birth weight (Ob-AGA group) and 44 obese pregnant women born themselves SGA (Ob-SGA group). Mean birth weight of newborn infants in Ob-SGA group was significantly less than in normal and Ob-AGA groups. Cholesterol and lipoproteins were significantly elevated in obese women (more prominent in Ob-SGA group). Most amino acid concentrations and fetal-maternal amino acid gradients were significantly lower in Ob-SGA group. These data suggest significant changes in placental amino acid transport/synthetic function in obese women who were born themselves SGA.

Abstract
Maternal physiological hypercholesterolemia occurs during pregnancy, ensuring normal fetal development. In some cases, the maternal plasma cholesterol level increases to above this physiological range, leading to maternal supraphysiological hypercholesterolemia (MSPH). This condition results in endothelial dysfunction and atherosclerosis in the fetal and placental vasculature. The fetal and placental endothelial dysfunction is related to alterations in the L-arginine/nitric oxide (NO) pathway and the arginase/urea pathway and results in reduced NO production. The level of tetrahydrobiopterin (BH4), a cofactor for endothelial NO synthase (eNOS), is reduced in nonpregnant women who have hypercholesterolemia, which favors the generation of the superoxide anion rather than NO (from eNOS), causing endothelial dysfunction. However, it is unknown whether MSPH is associated with changes in the level or metabolism of BH4; as a result, eNOS function is not well understood. This review summarizes the available information on the potential link between MSPH and BH4 in causing human fetoplacental vascular endothelial dysfunction, which may be crucial for understanding the deleterious effects of MSPH on fetal growth and development.

Abstract
Background Vitamin D deficiency is a common nutritional issue and dietary supplementation in the general population, including pregnant women, is generally advised. Appropriately high levels of vitamin D are expected to play a role in containing the glycemic and atherogenic profiles observed in pregnancy. However, the relation between vitamin D status and the lipid metabolic profile in Saudi women, who are known to suffer from chronic vitamin D deficiency and high incidence of obesity and type II DM, during the course of pregnancy is not known. Methods In this study, we analyzed the relation between serum vitamin D level and various serum metabolic markers among Saudi women (n = 515) in their first trimester of pregnancy (11.2 ± 3.4 weeks). Coefficients of Pearson correlation and Spearman rank correlation were calculated for Gaussian and non-Gaussian variables, respectively. Serum vitamin D status was defined as (in nmol/L): deficient (<25), insufficient (25–50); sufficient (50–75) and desirable (>75). Results Results indicated that vitamin D status was sufficient in only 3.5 % of the study participants and insufficient and deficient in 26.2 % and 68.0 % of participants, respectively. Serum vitamin D values in the overall study population correlated positively with serum levels of total cholesterol (R = 0.172; p < 0.01), triglycerides (R = 0.184; p < 0.01) and corrected calcium (R = 0.141; p < 0.05). In the subgroup of vitamin D deficient subjects (n = 350), log serum vitamin D values correlated with serum triglycerides (R = 0.23; p = 0.002) and cholesterol (R = 0.26; p = 0.001). Conclusions The positive correlations between serum vitamin D and the atherogenic factors such as total cholesterol and triglycerides indicate a pro-atherogenic metabolic status in vitamin D deficient expectant mothers. This may represent an adaptation to the high metabolic demands of pregnancy.

[PMID: 26382609 DOI: 10.1016/j.yrtph.2015.08.007] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2015] [Revised: 08/11/2015] [Accepted: 08/31/2015] [Indexed: 12/15/2022]
Abstract
Bococizumab is a humanized monoclonal IgG2Δa antibody against proprotein convertase subtilisin/kexin type 9 (PCSK9) for the treatment of hyperlipidemia. The evaluation of potential effects on embryo-fetal development was conducted in the rat. In a pharmacokinetic/pharmacodynamic study bococizumab was administered intravenously to pregnant Sprague-Dawley (SD) rats (n = 8/group) at 0, 10, 30, and 100 mg/kg during organogenesis. Maternal and fetal bococizumab, total cholesterol and HDL concentrations were determined. Bococizumab was well tolerated and there were no effects on ovarian or uterine parameters. Maternal and fetal bococizumab exposure increased with increasing dose, with a corresponding dose-dependent decrease in fetal cholesterol levels. Maternal cholesterol levels were decreased significantly, with reductions that were of a similar magnitude regardless of dose. In the definitive embryo-fetal development study bococizumab was administered to pregnant SD rats (n = 20/group) at 0, 10, 30, and 100 mg/kg and no adverse maternal or developmental effects were observed up to 100 mg/kg. These studies have provided an appropriate and relevant safety assessment of bococizumab in pregnant rats to inform human risk assessment, demonstrating no adverse effects on embryo-fetal development at magnitudes greater than anticipated clinical exposure and in the presence of maximal reductions in maternal cholesterol and dose-dependent reductions in fetal cholesterol.

Maternal inheritance does not predict cholesterol levels in children with familial hypercholesterolemia. Atherosclerosis 2015; 243:155-60. [PMID: 26386212 DOI: 10.1016/j.atherosclerosis.2015.09.014] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2015] [Revised: 09/07/2015] [Accepted: 09/07/2015] [Indexed: 11/22/2022]
Abstract
BACKGROUND AND AIMS Pregnancy exerts metabolic changes with increasing levels of total cholesterol and triglycerides as prominent features. Maternal hypercholesterolemia may thus contribute to an unfavorable in utero environment potentially influencing the susceptibility of adult cardiovascular disease in the offspring. We investigated the impact of maternal familial hypercholesterolemia (FH) on pre-treatment plasma lipids and C-reactive protein (CRP) levels in non-statin treated FH children. METHODS Children with FH (n = 1063) aged between 0 and 19 years were included. Of these, 500 had inherited FH maternally, 563 paternally and 97.6% had a verified FH mutation. Information about inheritance, mutation type and pretreatment levels of blood lipids and CRP was retrieved from the medical records. RESULTS There were no significant differences in the plasma levels of lipids and C-reactive protein (CRP) in children with maternal FH compared with children with paternal FH, (0.12 ≤ P ≤ 0.90). Independent of which parent transmitted FH, children with LDL receptor negative mutations had significantly higher levels of total and LDL cholesterol and Apolipoprotein (Apo) B, and lower levels of HDL cholesterol and ApoA1, compared with children with other LDL receptor mutations (P < 0.001). CONCLUSION Maternal inheritance of FH was not associated with detectable long-term effects in the offspring's phenotype measured by adverse lipid profiles and increased CRP levels, whereas a LDL receptor negative mutation was associated with an unfavorably phenotype in FH offspring. Our findings do not support the fetal origin of adulthood disease hypothesis, while at the same time not excluding the hypothesis since other pathways leading to atherosclerosis may be involved.

Abstract
The aim of this article is to determine whether the age of a woman at first birth is associated with treatment for high blood pressure (HBP) later in life.Baseline data for 62,914 women were sourced from the "45 and Up Study," an observational cohort study of healthy aging in Australia. These women had given first birth between the ages of 18 and 45 years. Odds ratios and 95% confidence intervals for the association between age that a woman gave first birth and treatment for HBP were estimated using logistic regression. Data were stratified by current age (<60 and ≥60 years) and adjusted for demographic and lifestyle factors.There was a significant association between age at first birth and present day HBP. Older age at first birth was associated with a lower likelihood of HBP in women aged 25 to <35 years and 35 to 45 years at first birth (in women currently <60 years) and 35 to 45 years at first birth (in women currently ≥60 years of age), compared with women aged 18 to <25 years at first birth, adjusting for demographic and lifestyle factors.Women who were older when they gave first birth had lower odds of treatment for HBP compared with women who were younger when they gave birth to their first child. The contribution of a woman's pregnancy history, including her age at first birth, should be discussed with a patient when assessing her risk of HBP.

Abstract
AIMS Higher parity has been associated with increased maternal risk of cardiovascular disease, but the mechanism is not well delineated. Whether the number of live births is associated with coronary and aortic subclinical atherosclerosis has not been fully evaluated. METHODS AND RESULTS Women from the Dallas Heart Study, a multiethnic population-based cohort of subjects aged 30-65 years, were included if they had data on self-reported live births and coronary artery calcium (CAC) measured by computed tomography or aortic wall thickness (AWT) by MRI. Coronary artery calcium was positive if >10 Agatston units, and aortic wall thickness if greater than the 75(th) percentile reference point for age and gender. Among the 1644 women included in the study, the mean age was 45 years and 55% were Black. Sequential multivariable models were done adjusting for age, race, traditional cardiovascular risk factors, body mass index, income, education, hormone replacement therapy, oral contraceptives, and physical activity. Using women with 2-3 live births as the reference, those with four or more live births had an increased prevalence of elevated coronary artery calcium (odds ratio (OR) 2.2, 95% confidence interval (CI) 1.28-3.65) and aortic wall thickness (OR 1.6, 95% CI 1.04-2.41). Women with 0-1 live births also had increased coronary artery calcium (OR 1.9, 95% CI 1.16-3.03) and aortic wall thickness (OR 1.5, 95% CI 1.05-2.09) after multivariable adjustment. CONCLUSION The number of live births is associated with subclinical coronary and aortic atherosclerosis, with an apparent U-shaped relationship. Further studies are needed to confirm this association and explore the biological underpinnings of these findings.

Abstract
Pregnancy and childbirth are associated with hemodynamic changes and vascular remodeling. It is not known whether parity is associated with later adverse vascular properties such as larger arterial diameter, wall thickness, and lower distensibility. We used baseline data from 3283 women free of cardiovascular disease aged 45 to 84 years enrolled in the population-based Multi-Ethnic Study of Atherosclerosis. Participants self-reported parity status. Ultrasound-derived carotid artery lumen diameters and brachial artery blood pressures were measured at peak-systole and end-diastole. Common carotid intima-media thickness was also measured. Regression models to determine the association of carotid distensibility coefficient, lumen diameter, and carotid intima-media thickness with parity were adjusted for age, race, height, weight, diabetes mellitus, current smoking, blood pressure medication use, and total and high-density lipoprotein cholesterol levels. The prevalence of nulliparity was 18%. In adjusted models, carotid distensibility coefficient was 0.09×10−5 Pa−1 lower (P=0.009) in parous versus nulliparous women. Among parous women, there was a nonlinear association with the greatest carotid distensibility coefficient seen in women with 2 live births and significantly lower distensibility seen in primiparas (P=0.04) or with higher parity >2 (P=0.005). No such pattern of association with parity was found for lumen diameter or carotid intima-media thickness. Parity is associated with lower carotid artery distensibility, suggesting arterial remodeling that lasts beyond childbirth. These long-term effects on the vasculature may explain the association of parity with cardiovascular events later in life.

Abstract
Changes in lipid metabolism have been shown to occur during pregnancy. The thyroid hormones affect lipid metabolism. The present study was carried out to find out whether the last trimester of pregnancy affects thyroid hormones, thyroid-stimulating hormone (TSH), lipid, and lipoprotein profile in healthy dromedary camels. Twenty clinical healthy dromedary camels aged between 4-5 years were divided into two equal groups: (1) pregnant camels in their last trimester of pregnancy and (2) non-pregnant age-matched controls. Thyroid function tests were carried out by measuring serum levels of TSH, free thyroxin (fT4), total thyroxin (T4), free triiodothyronine (fT3), and total triiodothyronine (T3) by commercially available radio immunoassay kits. Total cholesterol (TC), triglyceride (TG), and high-density lipoprotein (HDL) cholesterol were analyzed using enzymatic/spectrophotometric methods while low-density lipoprotein (LDL) cholesterol, very low-density lipoprotein (VLDL), and total lipid (TL) were calculated using Friedewald's and Raylander's formula, respectively. Serum levels of TSH and thyroid hormones except fT4 did not show any significant difference between pregnant and non-pregnant camels. fT4 level was lower in the pregnant camels (P < 0.05). Serum levels of total cholesterol, triglyceride, total lipid, LDL cholesterol, HDL cholesterol, and VLDL did not show significant difference between pregnant and non-pregnant camels. All of these variables in pregnant camels were higher than non-pregnant. Based on the results of this study, the fetus load may not alter the thyroid status of the camel and the concentrations of thyroid hormones were not correlated with TSH and lipid profile levels in the healthy pregnant camels.

Abstract
BACKGROUND Dyslipidemia, a major risk factor for cardiovascular disease is a common finding in patients with type 2 diabetes and among women with gestational diabetes. Elevated levels of lipoprotein(a) [Lp(a)] are linked to increased risk of cardiovascular disease. However, its relationship with insulin resistance, type 2 diabetes and gestational diabetes is controversial and unproven. Here we aimed to clarify whether Lp(a) levels are associated with insulin sensitivity in pregnancy. METHODS Sixty-four women with gestational diabetes and 165 with normal glucose tolerance were enrolled in the study. Fasting Lp(a) serum levels were measured in all women at 24-28 weeks of gestation. RESULTS In pregnancy, there was no significant difference in serum Lp(a) concentrations between the two groups. Its level did not correlate with markers of insulin resistance (HOMA-IR), insulin sensitivity (HOMA-S%), pancreatic beta-cell function (HOMA-B%) and insulin sensitivity in dynamic conditions (OGIS). In addition, fasting glucose and insulin levels and those throughout an oral glucose tolerance test were independent of Lp(a) concentrations in our study group. CONCLUSIONS Lp(a) levels in pregnant women do not differ with respect to the presence or absence of gestational diabetes. Although influenced by some components of the lipid profile, such as triglycerides and HDL-C, insulin resistance in pregnancy is not affected by Lp(a).

Abstract
Studies in children and adults have resulted in conflicting evidence in the quest for the answer to the hypothesis that offspring from hypercholesterolemic mothers might have an increased cardiovascular risk. Previous studies might have suffered from limitations such as cohort size and clinical sampling bias. We therefore explored this hypothesis in large cohorts of both subjects with familial hypercholesterolemia (FH) and unaffected siblings in a wide age range. In three cohorts (cohort 1: n = 1,988, aged 0-18 years; cohort 2: n = 300, 8-30 years; cohort 3: n = 369, 18-60 years), we measured lipid and lipoproteins as well as carotid intima-media thickness (c-IMT) in offspring from FH mothers versus FH fathers. For LDL cholesterol, triglycerides (TGs), and c-IMT, we performed a pooled analysis. No significant differences could be observed in c-IMT, lipid, or lipoprotein levels from offspring of FH mothers versus FH fathers. Pooled analyses showed no significant differences for either LDL cholesterol [mean difference 0.02 (-0.06,0.11) mmol/l, P = 0.60], TGs [mean difference 0.07 (0.00,0.14) mmol/l, P = 0.08], or c-IMT [mean difference -0.00 (-0.01,0.01) mm, P = 0.86]. Our data do not support the hypothesis that cardiovascular risk markers are different between offspring from FH mothers and FH fathers.

Abstract
BACKGROUND The plasma lipid profile changes atherogenically during normal pregnancy. Gestational diabetes mellitus (GDM) can exacerbate the changes in metabolism. The logarithm of the ratio triglycerides/HDL-cholesterol is an atherogenic index of the plasma (AIP) and can be used as a marker for plasma atherogenicity. METHODS Serum of 576 unrelated Euro-Brazilian pregnant women was collected and the subjects were classified as healthy pregnant women (control, n=288) and gestational diabetic patients (GDM, n=288) according to the ADA 2010 criteria. Both studied groups were sub classified in 4 gestational periods: (i) 12-23, (ii) 24-28, (iii) 29-32 and (iv) >32 weeks of gestation. RESULTS Except for the AIP, the other parameters showed low discrimination between control and GDM groups (ROC curves). When analyzed by ROC curves the AIP of subjects in the early period of gestation showed sensitivity and specificity of 82.6% and 83.4%, respectively, with a cut-off point of 0.099 (AUC 0.886, P<0.0001). CONCLUSIONS The AIP is a valuable index to identify pregnant women with low risk of gestational diabetes before 24 weeks of gestation.

Abstract
Pre-eclampsia is a syndrome of pregnancy, defined by the gestational-onset of hypertension and proteinuria, which resolves postpartum. This definition does not consider the variable multiorgan involvement of a syndrome that can include seizures, fulminating hepatic necrosis and a consumptive coagulopathy. These disparate clinical features are a consequence of an accelerated but transient metabolic syndrome with widespread maternal endothelial dysfunction and inflammation. A trigger to this maternal state is the relatively ischaemic placenta. As pregnancy progresses, the concentration of vaso-toxic factors released by the relatively ischaemic placenta gradually builds up in the maternal circulation. Those predisposed to endothelial dysfunction, e.g. women with risk factors for cardiovascular disease, are more sensitive to these placental derived factors and will develop pre-eclampsia before natural onset of labour. A woman's vulnerability to pre-eclampsia is therefore composed of a unique balance between her pre-existing maternal endothelial and metabolic health and the concentration of placental derived factors toxic to maternal endothelium. Delivery of the placenta remains the only cure. Years later, women who had pre-eclampsia are at increased risk of chronic hypertension, ischaemic heart disease, cerebrovascular disease, kidney disease, diabetes mellitus, thromboembolism, hypothyroidism and even impaired memory. This article describes how a brief, usually single episode of this acute pregnancy syndrome might both identify those vulnerable to chronic disease in later life and in some cases initiate chronic disease.

Abstract
We analyzed 27,578 CpG sites that map to 14,495 genes in omental arteries of normal pregnant and preeclamptic women for DNA methylation status using the Illumina platform. We found 1685 genes with a significant difference in DNA methylation at a false discovery rate of <10% with many inflammatory genes having reduced methylation. Unsupervised hierarchical clustering revealed natural clustering by diagnosis and methylation status. Of the genes with significant methylation differences, 236 were significant at a false discovery rate of <5%. When data were analyzed more stringently to a false discovery rate of <5% and difference in methylation of >0.10, 65 genes were identified, all of which showed reduced methylation in preeclampsia. When these genes were mapped to gene ontology for molecular functions and biological processes, 75 molecular functions and 149 biological processes were overrepresented in the preeclamptic vessels. These included smooth muscle contraction, thrombosis, inflammation, redox homeostasis, sugar metabolism, and amino acid metabolism. We speculate that reduced methylation may contribute to the pathogenesis of preeclampsia and that alterations in DNA methylation resulting from preeclampsia may increase maternal risk of cardiovascular disease later in life.

Abstract
BACKGROUND Preeclampsia (PE) is a multi-causal disease characterized by the development of hypertension and proteinuria in the second half of pregnancy. Multiple risk factors have been associated with the development of PE. Moreover, it is known that these risk factors vary between populations from developed and developing countries. The aim of this study is to identify which risk factors are associated with the development of preeclampsia (PE) among Colombian women. METHODS A multi-centre case-control study was conducted between September 2006 and July 2009 in six Colombian cities. Cases included women with PE (n = 201); controls were aged-matched pregnant women (n = 201) without cardiovascular or endocrine diseases for a case-control ratio of 1:1. A complete medical chart, physical examination and biochemical analysis were completed before delivery. Multivariable logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI) of potential risk factors associated with PE. RESULTS The presence of factors present in the metabolic syndrome cluster such as body mass index >31 Kg/m2 (OR = 2.18; 1.14-4.14 95% CI), high-density lipoprotein <1.24 mmol/L (OR = 2.42; 1.53-3.84 95% CI), triglycerides >3.24 mmol/L (OR = 1.60; 1.04-2.48 95% CI) and glycemia >4.9 mmol/L (OR = 2.66; 1.47-4.81 95%CI) as well as being primigravidae (OR = 1.71; 1.07-2.73 95% CI) were associated with the development of PE, after adjusting for other variables. CONCLUSION Factors present in the cluster of metabolic syndrome and primigravidity were associated with a greater risk of PE among Colombian women. Understanding the role of this cluster of risk factors in the development of PE is of crucial importance to prevent PE and remains to be determined.

Abstract
Gestational hypertriglyceridaemia is a rare cause of acute pancreatitis. Its pathophysiology is incompletely understood. Severity scoring and effective management remain challenging. We report a case of acute pancreatitis secondary to gestational hypertriglyceridaemia. We describe the use of computed tomography to provide an alternative determination of severity, as well as plasmapheresis as a means of treating the condition.

Abstract
BACKGROUND Maternal plasma lipids, including total cholesterol, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), increase during pregnancy, remaining elevated over prepregnancy levels through the immediate postpartum period. Triglycerides decrease rapidly to prepregnancy levels after delivery. Few data on postpartum lipid levels are available, and levels in postpartum women with depression have not been evaluated. We sought to determine the cross-sectional levels of total cholesterol, LDL-C, HDL-C, and triglycerides between 1 and 14 weeks postpartum in postpartum women with DSM-4 diagnoses of major depression and determine if they are similarly elevated to published levels in other postpartum populations. METHODS As part of screening for a randomized controlled trial comparing treatments for postpartum depression (PPD), women (n=120) had postpartum fasting lipid levels determined. Linear regression models were used to assess the association between time postpartum and lipid levels. Analysis of covariance models (ANCOVA) assessed the association of baseline characteristics with lipids. RESULTS Total cholesterol levels were >200 mg/dL in 45% of the sample at baseline. Mean baseline total cholesterol was 196±39 mg/dL. There was an inverse linear relationship between postpartum week and total cholesterol, with cholesterol values decreasing an average of 4.5 mg/dL per week. Similarly, LDL-C and HDL-C trended down over time. Triglycerides were stable and within the normal range during the observation period. CONCLUSIONS Total cholesterol, HDL-C, and LDL-C are significantly elevated in the early postpartum period and do not return to <200 mg/dL until 6 weeks postpartum in women with PPD. The magnitude and duration of elevation are consistent with the sparse published data on nondepressed women.

Abstract
As part of a feasibility study to prevent gestational diabetes mellitus (GDM), we evaluated the effect of an intensive dietary therapy on quality of diet, weight gain and birth weight in women at high risk of GDM. Women with risk factors for GDM (n 54) were randomly assigned from April 2005 to May 2006 to a lifestyle intervention group (n 27) including dietary advice six times during pregnancy or to a close follow-up group (n 27) in a community-based setting in Finland. Dietary intake was recorded three times during pregnancy using 4 d food records. The main outcome was the incidence of GDM. The secondary outcomes were the changes in nutrient intake, weight gain and birth weight. Overall, seventeen (65 %) women in the intervention group and eighteen (69 %) women in the close follow-up group returned all three food records. PUFA intake increased (P = 0·008) during pregnancy in the intervention as compared to the close follow-up group. There were no clear differences in the changes of saturated fat or fibre intake between the groups. Intensive dietary education resulted in a somewhat lower weight gain during pregnancy (P = 0·062) and higher birth weights of the infants (P = 0·047) without an effect on macrosomia as compared to the close follow-up group. Individualised counselling by a clinical nutritionist as part of a lifestyle intervention improved the quality of dietary fat intake in pregnant women at high risk of GDM.

Abstract
PURPOSE OF REVIEW The present review aims to highlight the consequences for mother and child of profound hypercholesterolemia during pregnancy of women with familial hypercholesterolemia. RECENT FINDINGS Familial hypercholesterolemia is increasingly diagnosed in younger patients due to the existence of screening programs and more widespread cholesterol testing. Increasing numbers of young female patients with familial hypercholesterolemia raise the issue of pregnancy and its consequences for the familial hypercholesterolemia patient herself but also for her offspring. When pregnancy is considered, lipid-lowering drugs are often discontinued because of the fear for teratogenic effects. The evidence for teratogenesis associated with statin use is scant and conflicting. On the other hand, several studies do suggest that pronounced hypercholesterolemia during pregnancy has adverse effects on both fetus and mother. In fact, human and animal studies reveal an enhanced tendency toward atherosclerosis in the offspring of women who suffer from hypercholesterolemia during pregnancy. In animal studies, some evidence exists that this can be reversed by treatment with lipid-lowering and antioxidative agents. Until today, however, no human studies exist that have evaluated efficacy or safety of lipid-lowering interventions in pregnant women with familial hypercholesterolemia. SUMMARY Altogether, the suggested relationship between severe hypercholesterolemia and enhanced atherosclerosis in offspring and possibly the mother warrants further confirmation and, consequently, studies that focus on therapeutic strategies that can safely lower cholesterol levels during pregnancy in these women.

Abstract
Lipid Profile of Healthy Women During Normal PregnancyThe four basic lipid indexes (Chol, Trig, HDL-C and LDL-C) increase during pregnancy, following different rates of increase. Among the four analytes triglycerides show the largest increase and HDL-C the smallest. All analyte values are raised during the 40 weeks of pregnancy, except HDL-C which is stabilized during the second trimester. After delivery the values decrease, except LDL-C which remains steady (for some weeks) before starting to fall following the others. In this study the relations between the four lipid indexes and some predisposing factors (age, gestational age, nationality, body mass index, profession, smoking and diabetes during pregnancy) were investigated. The sample consisted of 413 pregnant women, mainly Greeks and Albanians. After regression analysis it was proved that the only common predisposing factor was the gestational age. Triglycerides and total cholesterol are also influenced by the women's age. The lipid indexes showed no important difference between the pregnant women in the first trimester and the non-pregnant women. On the contrary, there was a statistical difference between the pregnant women in the second and third trimester and between them and the women in the first trimester. The percentages of increase between first and second trimester were: Chol: 38%, Trig: 115%, HDL-C: 30%, LDL-C: 33%. The percentages of increase between first and third trimester were: Chol: 65%, Trig: 208%, HDL-C: 26%, LDLC: 64%.

Abstract
Clinical safety of consuming plant stanol ester spreads during pregnancy and lactation, the impact on maternal and infant serum and breast-milk cholesterol and the ratios (μmol/mmol of cholesterol) of synthesis and absorption markers were evaluated. Pregnant women (n21) were randomised to control and dietary intervention groups, the intervention including advice to follow a balanced diet and to consume spreads enriched with plant stanol esters. Participants were followed during and after pregnancy and their infants up to 1 year of age. A mean 1·1 (sd0·4) g consumption of plant stanols during pregnancy and 1·4 (sd0·9) g 1 month post-partum increased sitostanol and the markers for cholesterol synthesis, lathosterol, lathosterol/campesterol and lathosterol/sitosterol, and reduced a marker for cholesterol absorption, campesterol, in maternal serum. In breast milk, desmosterol was lower in the intervention group, while no differences were detected between the groups in infants' serum. Plant stanol ester spread consumption had no impact on the length of gestation, infants' growth or serum β-carotene concentration at 1 and 6 months of age, but the cholesterol-adjusted serum β-carotene concentration was lowered at 1 month in the intervention group. Plant stanol ester spread consumption appeared safe in the clinical setting, except for potential lowering of infants' serum β-carotene concentration, and was reflected in the markers of cholesterol synthesis and absorption in mothers' serum, encouraging further studies in larger settings.

Abstract
OBJECTIVE Preeclampsia is associated with cardiovascular atherosclerotic events later in life. However, little is known about earlier subclinical signs of atherosclerosis. We aimed to investigate whether women who recently had preeclampsia show increased intima-media thickness (IMT), as marker of early atherosclerosis, compared with women with normal pregnancies or nulliparous women. METHODS Intima-media thickness of carotid and femoral arteries measured by ultrasonography, and possible confounding risk factors as body mass index, blood pressure, serum lipids, smoking status, and family history of cardiovascular disease were compared among 22 nulliparous women, 22 primiparous women with normal pregnancy, and 22 primiparous women with early-onset preeclampsia at least 3 months postpartum and 6 weeks after ending lactation RESULTS Except for slightly higher values for blood pressure, triglycerides, and homocysteine in the formerly preeclamptic women, no other clinical or biochemical differences were observed. The preeclampsia group showed an increased IMT (mean +/- standard deviation, 0.63 +/- 0.14 mm) of the common femoral artery compared with the normal pregnancy group (0.55 +/- 0.06 mm, P = .005) and to the nulliparous group (0.52 +/- 0.06 mm, P < .001). These differences remained significant after correction for possible confounders by multiple linear regression analyses. An increase in IMT of the common carotid artery between the normal pregnancy and the nulliparous group was observed, which became significant after adjustment for confounders. CONCLUSION Preeclampsia and, to a lesser degree, normal pregnancy are associated with increased IMT. The association between increased IMT and (preeclamptic) pregnancy leads to the question of which comes first, which should be addressed in follow-up studies. LEVEL OF EVIDENCE II-2.

Abstract
BACKGROUND High-density lipoprotein cholesterol (HDL-C) levels in premenopausal and postmenopausal women are differentially affected by exogenous sex hormones depending on their apolipoprotein E (apo E) genotype. Because endogenous sex hormones markedly increase during pregnancy, we examined whether HDL-C declines after a first birth varied by apo E polymorphisms. METHODS In 1147 nulliparas (416 black, 731 white), fasting blood samples (nonpregnant) were drawn at baseline and at follow-up years 5, 7, and 10. Time-dependent pregnancy groups included 0 pregnancies (P0), 1+ short pregnancy (P1+), 1 birth (B1), 2 or more births (B2+). ApoE groups by alleles identified with a phenotype method included E4 (4/3 and 4/4), E3 (3/3), and E2 (2/2 and 3/2). Differences in adjusted mean HDL-C changes among pregnancy groups and ApoE groups were examined using repeated measures multiple linear regression. RESULTS HDL-C declines associated with parity (one or more births) depended on ApoE group (ApoE*Pregnancy Interaction; p < 0.002). For B1 and B2+ vs. P0, HDL-C declines were -2.4 to -2.7 mg/dl in E4 and -3.4 to -4.1 mg/dl in E3. In E2, HDL-C declines were -6.6 mg/dl for one birth, and -11.5 mg/dl for two or more births, each relative to the 0 pregnancies (P0) group (linear trend, p < 0.001). CONCLUSIONS The degree to which childbearing adversely affects long-term HDL-C declines varies by apo E phenotype, based on a method that accurately classifies genotype. Our findings show that 2/2 and 3/2 genotypes are associated with larger parity-related HDL-C declines than 3/3, 4/3, and 4/4 genotypes.

Abstract
PURPOSE A predisposition to coronary artery disease (CAD) may put women at risk for preeclampsia. Morbid preeclampsia (early, severe, recurrent, and with neonatal morbidity) represents the subset of preeclampsia of greatest public health concern. METHODS We review here the published links between preeclampsia and CAD. RESULTS Many risk factors are common to both CAD and preeclampsia. These include obesity; elevated blood pressure; dyslipidemia; insulin resistance; and hyperglycemia, together termed "Syndrome X"; as well as endothelial dysfunction; hyperuricemia; hyperhomocysteinemia; and abnormalities of inflammation, thrombosis, and angiogenesis. After pregnancy, women with preeclampsia are more likely to experience later life CAD. CONCLUSIONS Both the association between CAD risk factors and preeclampsia and the association between preeclampsia and later CAD appears to be more pronounced among the subset of women with morbid preeclampsia. Thus, women at elevated risk for CAD may be at particularly high risk for morbid preeclampsia and women with morbid preeclampsia may be those at highest risk for later life CAD.

Abstract
PURPOSE OF REVIEW This review describes how the physiological demands of pregnancy act as a maternal stress test that can predict a woman's health in later life. Pregnancy transiently catapults a woman into a metabolic syndrome that predisposes to vascular endothelial dysfunction. Women who are already predisposed to this phenotype develop gestational hypertension or diabetes mellitus, which re-emerge in later life as the metabolic syndrome returns. Pregnancy can also temporarily unmask sub-clinical disease, which may return in later life when the effects of ageing diminish the limited reserves of a vulnerable organ. RECENT FINDINGS Recent studies have attempted to assess how gestational syndromes affect the risk for a woman of developing a diverse range of diseases in later life. As well as cardiovascular disease and diabetes mellitus, pregnancy can reveal a vulnerability to thyroid and pituitary disorders, liver and renal disease, depression, thrombosis and even cancer. SUMMARY Although our knowledge of this phenomenon is incomplete, women who have had gestational syndromes, in particular pregnancy-induced hypertension/preeclampsia or gestational diabetes, should make lifestyle changes that will reduce their risk of cardiovascular disease in later life.

Abstract
Previous studies have reported declines in high density lipoprotein (HDL) cholesterol 1-2 years after pregnancy. In 1986-1996, the authors prospectively examined the association between childbearing and changes in fasting plasma lipids (low density lipoprotein, HDL, and total cholesterol; triglycerides) among 1,952 US women (980 Black, 972 White) in the Coronary Artery Risk Development in Young Adults study. Repeated-measures multiple linear regression was used to examine lipid changes over three time intervals (baseline to years 5, 7, and 10) in time-dependent follow-up groups: P0 (0 pregnancies), P1 (>/=1 miscarriages/abortions), B1 (1 birth), and B2 (>/=2 births). Means stratified by race and baseline parity (nulliparous or parous) were fully adjusted for study center, time, height, baseline diet, and other baseline and time-dependent covariates (age, smoking, education, weight, waist circumference, alcohol intake, oral contraceptive use, physical activity, short pregnancies). For both races, fully adjusted HDL cholesterol declines of -3 to -4 mg/dl were associated with a first birth versus no pregnancies during follow-up (p < 0.001). Higher-order births were not associated with greater declines in HDL cholesterol (B2 similar to B1, no association among women parous at baseline). In Whites, total and low density lipoprotein cholesterol declines were associated with follow-up births. HDL cholesterol declines of -3 to -4 mg/dl after a first birth persisted during the 10 years of follow-up independent of weight, central adiposity, and selected behavior changes.

Abstract
BACKGROUND The physiopathological relevance of plasma lipid concentrations is supported by the observation that they might affect the physicochemical properties of the plasma membrane of circulating cells and might be crucial in the pathological conditions complicating pregnancy. METHODS Plasma and erythrocyte membrane lipid composition, membrane fluidity and function [membrane-bound enzyme sodium/potassium adenosine triphosphatase (Na+/K+-ATPase) activity] were studied in 24 healthy women in the nonpregnant condition and at 12, 24 and 38 weeks' gestation. RESULTS The plasma showed an increase in total and high density lipoprotein (HDL) cholesterol, triglyceride (TG) and phospholipid (PL) levels. In the erythrocyte membrane we found the cholesterol/phospholipid (C/PL) ratio increased and the saturated to unsaturated fatty acid (FA) ratio (Sat/Unsat) significantly reduced; fluorescence polarization showed an initial increase during pregnancy and a progressive decrease afterwards; Na+/K+-ATPase activity was progressively reduced. CONCLUSIONS A generalized alteration in the composition and function of the maternal erythrocyte membrane is present during a physiological pregnancy, and these modifications may involve a more complex physiopathogenetic mechanism.

Abstract
BACKGROUND Parity is associated with coronary heart disease (CHD) risk. In the present study, we assessed the associations between number of children and CHD in both women and men. METHODS AND RESULTS A total of 4286 women and 4252 men aged 60 to 79 years from 24 British towns were studied. Number of children was positively associated with body mass index and waist-hip ratio in both sexes. In women but not in men, number of children was inversely associated with high-density lipoprotein cholesterol and was positively associated with triglycerides and diabetes. For both sexes, similar "J" shaped associations between number of children and CHD were observed, with the prevalence lowest among those with 2 children and increasing linearly with each additional child beyond 2. For those with at least 2 children, each additional child increased the age-adjusted odds of CHD by 30% (odds ratio, 1.30; 95% confidence interval, 1.17 to 1.44) for women and by 12% for men (odds ratio, 1.12; 95% confidence interval, 1.02 to 1.22). Adjustment for obesity and metabolic risk factors attenuated the associations between greater number of children and CHD in both sexes, although in women some association remained. CONCLUSIONS Lifestyle risk factors associated with child-rearing lead to obesity and result in increased CHD in both sexes; biological responses of pregnancy may have additional adverse effects in women.

Abstract
OBJECTIVE To determine whether, in normal pregnancies, there is evidence of oxidative stress that is related to the lipid changes observed in pregnancy. DESIGN Longitudinal study of healthy women having a normal pregnancy. Samples were obtained towards the end of each trimester and after 8 weeks postpartum. PATIENTS Seventeen healthy women during a normal singleton pregnancy were compared with 12 healthy, non-pregnant women. MEASUREMENTS Oxidative stress was determined by measuring total antioxidant capacity (TAC), uric acid and lipid hydroperoxides (LHP). Lipid status was evaluated by measuring total and high-density lipoprotein cholesterol, triglycerides and low-density lipoprotein (LDL) subfractions. RESULTS Pregnancy was associated with decreased TAC and uric acid in the first trimester, which gradually increased during pregnancy, reaching normal values during the postpartum period. LHP significantly increased towards the end of pregnancy. The changes observed in LHP were significantly correlated with increases in LDL subfraction profile. CONCLUSIONS Late pregnancy was associated with the formation of susceptible, oxidisable particles (high LDL score) and an increase in oxidative damage. These biochemical changes may be relevant for the long-term cardiovascular health of women, especially those of high parity or those who are at high risk for cardiovascular disease (e.g. women with diabetes).

Familial hypercholesterolaemia (FH) is an autosomal co-dominantly inherited condition resulting from mutations of the low-density lipoprotein (LDL) receptor which occur in heterozygous form in approximately one in 500 individuals. Clinically, FH is characterized by 2-3-fold elevation of serum LDL cholesterol levels, accelerated development of atherosclerotic vascular disease, and, if untreated, shortened lifespan. The Finnish population, which represents a genetic isolate, offers exceptional possibilities for genetic-epidemiological studies on FH, as a handful of founder gene mutations account for the majority of FH cases in Finland. This review summarizes data from our FH studies carried out since 1985. We wish to emphasize the continuum of genotype-phenotype relationships, the importance of molecular diagnosis, the detection of novel risk factors of vascular disease, and innovations inhibiting cholesterol absorption for the modern treatment of FH.
