Preeclampsia (PE) is a hypertensive disorder of pregnancy occurring in ~10% of women worldwide. Maternal obesity is a risk factor for PE and the effects on offspring are long-standing with increased incidence of cardiometabolic disease into adulthood. The maternal obesogenic environment may play a role in pregnancy outcomes and offspring in a sex-dependent manner; however, in the context of superimposed PE, it is not completely understood. Obese BPH/5 mice spontaneously exhibit late-gestational hypertension, fetal demise and growth restriction, and excessive gestational weight gain, similar to PE. We hypothesized that phenotypic differences exist between female and male BPH/5 offspring and maternal weight loss in BPH/5 during pregnancy would influence these phenotypic differences. Obese BPH/5 dams were calorie restricted via pair-feeding (PF) to match the food intake of C57 dams for the first 9 days of pregnancy. Offspring were fed an ad libitum (lib) diet until phenotypic analysis. Body weights (BW), visceral peri-gonadal and peri-renal white adipose tissue (WAT), hearts, and livers were recorded in BPH/5 and control C57 age-matched adult females and males born to ad lib fed and PF dams. Values are reported as mean ± standard error of the mean. As previously described, BPH/5 females born to ad lib fed dams are overweight with increased peri-renal and gonadal WAT, cardiomegaly, and hepatomegaly (1308 ±13.3 vs 979.9 ±82.3g in C57, p<0.05). BPH/5 male mice are underweight (23.8±1.6 vs C57: 27.9±1.6g) with increased peri-renal WAT (158± 23 vs C57: 53.25±10.3mg, p<0.05), and cardiomegaly (heart: BW 8.1±0.5 vs C57: 5.7±1.1, p<0.05). Without altering BPH/5 male or female offspring BW, peri-renal adiposity (males: 103.5±13mg, females: 73.2±10.3mg, p<0.05), cardiomegaly (males: 5.74±0.5, females: 6.03±0.4, p<0.05), and female hepatomegaly (1149.8 ±58.1mg, p<0.05) are significantly attenuated in PF BPH/5 dams. To conclude, reduction in the maternal obesogenic environment may play a role in BPH/5 sex-dependent phenotypic differences. Future investigations are necessary to understand the differences observed in BPH/5 male versus female mice into adulthood as well as the transgenerational impact of attenuated maternal obesity in pregnancy.

Preeclampsia (PE) is a hypertensive disorder of pregnancy occurring in approximately 10% of women worldwide. While it is life threatening to both the mother and baby, the only effective treatment is delivery of the placenta and fetus, which is often preterm. Maternal obesity is a risk factor for PE, and the effects of both on offspring are long standing with increased incidence of cardiometabolic disease in adulthood. Obese BPH/5 mice spontaneously exhibit excessive gestational weight gain and late-gestational hypertension, similar to women with PE, along with fetal growth restriction and accelerated compensatory growth in female offspring. We hypothesized that BPH/5 male offspring will demonstrate cardiovascular and metabolic phenotypes similar to BPH/5 females. As previously described, BPH/5 females born to ad libitum-fed dams are overweight with hyperphagia and increased subcutaneous, peri-renal, and peri-gonadal white adipose tissue (WAT) and cardiomegaly compared to age-matched adult female controls. In this study, BPH/5 adult male mice have similar body weights and food intake compared to age-matched control mice but have increased inflammatory subcutaneous and peri-renal WAT and signs of cardiovascular disease: left ventricular hypertrophy and hypertension. Therefore, adult male BPH/5 do not completely phenocopy the cardiometabolic profile of female BPH/5 mice. Future investigations are necessary to understand the differences observed in BPH/5 male and female mice as they age. In conclusion, the impact of fetal programming due to PE has a transgenerational effect on both male and female offspring in the BPH/5 mouse model. The maternal obesogenic environment may play a role in PE pregnancy outcomes, including offspring health as they age.

Preeclampsia (PE) is a hypertensive disorder of pregnancy and a leading cause of maternal and fetal mortality with maternal obesity as a risk factor. Decreasing white adipose tissue (WAT) via calorie restriction during the first half of pregnancy may alter the maternal-fetal environment to improve offspring outcomes. We hypothesized that pair-feeding BPH/5 dams during pregnancy will improve cardiometabolic risk and WAT pro-inflammatory cytokine expression in BPH/5 offspring in a sex-dependent manner. Previously, we showed that BPH/5 males, unlike females, have similar body weights, daily food intake, and circulating leptin levels as compared to age-matched control mice. Although, adult BPH/5 females and males have cardiomegaly and increased subcutaneous and peri-renal WAT mass compared to lean control mice. To investigate the prevention of maternal obesity on offspring outcomes, BPH/5 dams were pair-fed (PF) beginning at embryonic day (e)0.5 to C57 pregnant mice. Offspring cardiometabolic risk and WAT pro-inflammatory cytokine mRNA were measured using real time PCR in adult ad libitum fed offspring. Compared to controls, peri-renal WAT from BPH/5 males showed a 5-fold increase while females had a 15-fold increase in TNFa (n=3-6; p<0.05), 6-fold increase in PTGS-2 for males and 5-fold increase for females (n=3-6; p<0.05), and 3-fold increase in IL-6 for males and 1.25-fold increase for females (n=3-6; p<0.05) in subcutaneous WAT. Adult offspring born to PF BPH/5 dams had decreased expression in TNFa (male: 4-fold and female: 7-fold), PTGS-2 (male: 5-fold and female: 4-fold), and IL-6 (male: 10-fold; n=3-6; p<0.05). In conclusion, prevention of maternal obesity in BPH/5 dams attenuates cardiometabolic risks and reduces the pro-inflammatory WAT milieu in male and female offspring. The transgenerational effects during pregnancy is believed to be caused by an alteration in the maternal-fetal environment due to WAT pro-inflammatory adipokines. Future investigations are necessary to understand the differences observed in BPH/5 male versus female mice into adulthood as well as the transgenerational impact of attenuated maternal obesity in pregnancy.

Abstract BACKGROUND: Pregnant women with obesity are at increased risk for peripartum depression. Maternal obesity is also associated with reduced human placental lactogen (hPL) levels, and decreased hPL transcripts were reported in women with clinical depression. In addition, hPL production may be rescued in women with obesity that were subsequently diagnosed with gestational diabetes and treated with insulin (INS). Objective: Study the effect of INS treatment in pregnancy on the risk for postpartum psychological distress (PPD) in women with and without obesity. Study Design: Using data housed at the Manitoba Centre for Health Policy (2002–2017), cohorts of women (ages 15+) with a single live birth with and without obesity were developed using weight (≥85 and &lt;65.6 kg, respectively) and an average (1.63 m) height. Pre-existing mood and anxiety disorders within 5 years preceding delivery as well as gestational hypertension were excluded. After randomly selecting 1 birth per mother, cohorts were stratified by INS treatment during the gestational period. The risk of PPD within 1 year of delivery was assessed by Poisson regression analysis. Models were adjusted for maternal age and area-level income at delivery. Results: The risk of PPD was 27% greater among women with obesity versus without (adjusted rate ratio (aRR)=1.27, 95% CI 1.16–1.4, p&lt;0.0001). However, women with obesity treated with INS did not have a significantly different risk of PPD compared to women without obesity whether treated with INS (aRR=0.99, 95%CI 0.48–2.02, p=0.974) or not (aRR=1.16, 95%CI 0.86–1.56, p=0.328). This suggests that the risk of PPD among women with obesity may be reduced by INS treatment; however, our ability to detect a significant difference may be limited by small cohort numbers (46 women with obesity received INS in pregnancy) or confounders for receiving INS in pregnancy. Direct comparison of INS treatment within weight groups faced the same limitations but trended toward a reduction in women with obesity who received INS (aRR=0.91, 95%CI 0.68–1.22, p=0.531). The positive association between INS treatment in pregnancy and decreased risk of PPD in women with obesity was lost when pre-existing mood and anxiety disorder was not excluded. Inclusion of pre-existing diabetes in the adjusted models did not improve model fit or contribute significantly to the differences in PPD rates. Conclusions: Maternal obesity increases the risk for PPD but this risk may be reduced by gestational INS treatment in the absence of a pre-existing mood and anxiety disorders. This correlates with the decrease and increase in hPL levels reported previously with maternal obesity without and with INS treatment (for diabetes) in pregnancy, respectively. Thus, hPL levels may serve as a possible indicator of PPD risk and a potential target for gestational INS treatment.

Pheochromocytomas are rare tumors producing catecholamines that could be a cause of secondary hypertension. On that basis, pheochromocytoma can occur as an extremely rare cause of hypertension in pregnancy and if diagnosed late can lead to adverse maternal-fetal outcome. In this case report we describe a case of pheochromocytoma affected pregnancy with poor fetal outcome. A 27-year-old pregnant woman was admitted for severe pre-eclampsia due to pre-gestational hypertension that was diagnosed during the first trimester. Due to high and uncontrolled maternal blood pressure and the worsened maternal-fetal condition after the admission induction of fetal lung maturity and emergency cesarean section were performed, but with poor fetal outcome. Later, an adrenal gland mass was identified using abdominal ultrasound and confirmed by computed tomography. After surgical adrenalectomy blood pressure of the patient was normalized. Pheochromocytoma should be considered as a possible cause of hypertensive disorder during pregnancy, particularly in cases of severe and unresponsive hypertension in order to provide for timely and appropriate treatment.

In the face of the obesity epidemic around the world, attention should be focused on the role of maternal obesity in the development of pregnancy. The purpose of this analysis was to evaluate the prediction of preeclampsia (PE) and isolated gestational hypertension (GH) for a number of maternal factors, in order to investigate the importance of pre-pregnancy obesity (body mass index, BMI ≥ 30 kg/m2), compared to other risk factors (e.g., prior PE, pregnancy weight gain (GWG), infertility treatment, interpregnancy interval, family history, the lack of vitamin supplementation, urogenital infection, and socioeconomic factors). In total, 912 women without chronic diseases were examined in a Polish prospective cohort of women with a single pregnancy (recruited in 2015–2016). Separate analyses were performed for the women who developed GH (n = 113) vs. 775 women who remained normotensive, as well as for those who developed PE (n = 24) vs. 775 controls. The probability of each disease was assessed for the base prediction model (age + primiparity) and for the model extended by one (test) variable, using logistic regression. Three measures were used to assess the prediction: area under curve (AUC) of the base and extended model, integrated discrimination improvement (IDI) (the index shows the difference between the value of the mean change in the predicted probability between the group of sick and healthy women when a new factor is added to the model), and net reclassification improvement (NRI) (the index focuses on the reclassification table describing the number of women in whom an upward or downward shift in the disease probability value occurred after a new factor had been added, including results for healthy and sick women). In the GH prediction, AUC increased most strongly when we added BMI (kg/m2) as a continuous variable (AUC = 0.716, p < 0.001) to the base model. The highest IDI index was obtained for prior GH/PE (IDI = 0.068, p < 0.001). The addition of BMI as a continuous variable or BMI ≥ 25 kg/m2 improved the classification for healthy and sick women the most (NRI = 0.571, p < 0.001). In the PE prediction, AUC increased most strongly when we added BMI categories (AUC = 0.726, p < 0.001) to the base model. The highest IDI index was obtained for prior GH/PE (IDI = 0.050, p = 0.080). The addition of BMI categories improved the classification for healthy and sick women the most (NRI = 0.688; p = 0.001). After summing up the results of three indexes, the probability of hypertension in pregnancy was most strongly improved by BMI, including BMI ≥ 25 kg/m2 for the GH prediction, and BMI ≥ 30 kg/m2 for the PE prediction. Main conclusions: Pre-pregnancy BMI was the most likely factor to increase the probability of developing hypertension in pregnancy, compared to other risk factors. Hierarchies of PE and GH risk factors may suggest different (or common) mechanisms of their development.

We investigated if supplementing obese mothers (MO) with docosahexaenoic acid (DHA) improves milk long-chain polyunsaturated fatty acid (LCPUFA) composition and offspring anxiety behavior. From weaning throughout pregnancy and lactation, female Wistar rats ate chow (C) or a high-fat diet (MO). One month before mating and through lactation, half the mothers received 400 mg DHA kg−1 d−1 orally (C+DHA or MO+DHA). Offspring ate C after weaning. Maternal weight, total body fat, milk hormones, and milk nutrient composition were determined. Pups’ milk nutrient intake was evaluated, and behavioral anxiety tests were conducted. MO exhibited increased weight and total fat, and higher milk corticosterone, leptin, linoleic, and arachidonic acid (AA) concentrations, and less DHA content. MO male and female offspring had higher ω-6/ ω-3 milk consumption ratios. In the elevated plus maze, female but not male MO offspring exhibited more anxiety. MO+DHA mothers exhibited lower weight, total fat, milk leptin, and AA concentrations, and enhanced milk DHA. MO+DHA offspring had a lower ω-6/ω-3 milk intake ratio and reduced anxiety vs. MO. DHA content was greater in C+DHA milk vs. C. Supplementing MO mothers with DHA improves milk composition, especially LCPUFA content and ω-6/ω-3 ratio reducing offspring anxiety in a sex-dependent manner.

Background: A hypertensive disorder in pregnancy comprises one of the deadly triad along with hemorrhage and infection-that contributes greatly to maternal morbidity and mortality. The aim of this study was to compare the feto-maternal outcome in pregnancy induced hypertension with normotensive pregnant women.Methods: A cross sectional prospective study was conducted in Paropakar Maternity and Women’s Hospital from 1st February 2018 to 1st May 2018. All pregnant women seeking help for hypertension during this period was included in the study and were followed up to six weeks of postpartum period.Results: Total 40 patients were enrolled in each arm. The highest number of pregnancy induced hypertension cases was seen in age group 20-24years (32.5%) and were mostly primigravidas (60%). The commonest symptom in Pregnancy induced hypertension was headache 47.5 %. The mean hemoglobin value was 11.91 gm/dl, mean SGPT (Gestational hypertension 25.44 IU/L, preeclampsia 55.25 IU/L and eclampsia 32.17 IU/L) and mean platelet count was 1, 95,140 lakh/cumm in pregnancy induced hypertension. Mean prothrombin time in gestational hypertension was 13.78±0.7 seconds. Most common maternal complication was preterm labor and fetal complication was prematurity. The most common mode of delivery was vaginal.Conclusions: Pregnancy induced hypertension was more common in primigravida with young age group of 20-24 years and presented commonly with complain of headache. Preterm labor was the most common maternal complication similarly prematurity was the commonest fetal complication seen in pregnancy induced hypertension. Vaginal delivery was the commonest mode of delivery. Blood investigation showed significant thrombocytopenia in eclampsia and decreased prothrombin time in gestational hypertension.Keywords: Fetal outcome; maternal complications; pregnancy induced hypertension.

Background: A spectrum of hypertensive disorders in pregnancy contribute to maternal and perinatal morbidity and mortality. For prediction and early diagnosis of preeclampsia various biochemical markers, vascular function test and renal markers have been developed. The objective of the study is to measure the lactate dehydrogenase enzyme (LDH) levels in pregnant women with pregnancy induced hypertensive disorders and correlate the levels with the severity of condition, maternal and the perinatal outcome.Methods: In this prospective observational study, a total of 150 pregnant women were studied. Out of these 150 women, 30 women had normal blood pressure, 30 women had gestational hypertension, 30 women had mild preeclampsia, 30 women had severe preeclampsia and 30 women had eclampsia. The serum LDH levels were measured in third trimester and patients followed up until early postpartum period and babies were followed up till early neonatal period to assess the maternal and neonatal outcomes.Results: Higher lactate dehydrogenase enzyme (LDH) levels were observed in pregnant women with severe form of hypertensive disorder and those who had a poor maternal and perinatal outcome. This is statistically significant (p<0.001).Conclusions: Lactate dehydrogenase enzyme (LDH) level is a useful biochemical marker to assess and predict the severity of disease, maternal and perinatal outcome as higher levels of the enzyme are associated with worsening severity of disease, a poor maternal and perinatal outcome.
