The original publication reported that univariate analysis showed that a vertical skin incision in obese women undergoing Cesarean delivery was associated with a higher odds ratio for wound complications than a transverse skin incision. Multivariable analyses showed a reversal of the association (i.e. the odds of wound complications were lower in women with a vertical skin incision). However, there was an error in the way the variable was entered in the logistic analysis. Re-analysis with the correct coding of the variable indicates that a transverse skin incision is associated with decreased odds of wound complication compared to a vertical skin incision.

Obesity epidemic: impact from preconception to postpartum

The obesity epidemic is on the rise throughout the USA and the world. Not only does it affect the general population but it also specifically poses unique threats to a woman’s life in the antepartum, peripartum and postpartum periods. An increased BMI is associated with worse perinatal outcomes, including higher rates of preeclampsia (and other hypertensive disorders), macrosomia, other neonatal morbidities and gestational diabetes. Isolated maternal obesity and additional maternal diabetes predispose the infant to potential adult disease through fetal programming. This review of the literature examines the effects of obesity on a woman’s life, outlining complications beginning with preconception through the postpartum period.

Rate of Gestational Diabetes Mellitus and Pregnancy Outcomes in Patients with Chronic Hypertension

Objective This study aims to determine the rate of gestational diabetes mellitus (GDM) in pregnancies complicated by chronic hypertension and to compare the adverse outcomes in chronic hypertensive pregnancies with and without GDM. Study Design A secondary analysis from a multicenter trial of low-dose aspirin for preeclampsia prevention in women with chronic hypertension. The rate of GDM was evaluated among singleton pregnancies complicated with chronic hypertension and grouped according to their GDM status. Pregnancy outcomes and rates of preterm delivery < 35 weeks and < 32 weeks, preeclampsia, indicated preterm birth, small for gestational age, abruptio placentae, and perinatal death were compared between those with and without GDM. A subgroup analysis comparing women who developed superimposed preeclampsia with and without GDM was studied. Multivariate logistic-regression analysis was used to adjust for potentially confounding factors. Results A total of 763 women met the inclusion criteria: 129 (17%) developed GDM. Parity, race, maternal baseline blood pressure, antihypertensive drug use, and assignment to low-dose aspirin were not significantly different between the groups with and without GDM. Using univariate analysis, maternal age (33 vs. 24%, p = 0.03) and body mass index (88 vs. 57%, p < 0.001) were higher in those who had GDM, whereas the rate of preterm delivery < 32 weeks (12 vs. 5%, p = 0.02) was higher among those without GDM. Using logistic-regression analysis, the rate of composite adverse outcomes (adjusted odds ratio [aOR], 0.77; 95% confidence interval [CI], 0.41-1.47) that included indicated preterm birth, small for gestational age, abruptio placentae, and perinatal death showed no significant differences.Superimposed preeclampsia developed in 34 (26%) women with GDM and in 182 (29%) without GDM. When superimposed preeclampsia was present, it developed at an earlier gestational age among the group without GDM (35 ± 5 vs. 37 ± 3 weeks, p = 0.003), and had higher rates of small for gestational age infants (18 vs. 3%, p = 0.03). After adjustment for confounders, only length of stay in neonatal intensive care unit was longer for those without GDM who developed superimposed preeclampsia (aOR, 0.42; 95% CI, 0.2-0.93). Conclusion Women with chronic hypertension are at a high risk for developing GDM. Outcomes in patients with chronic hypertension and GDM are not significantly different from those with chronic hypertension only.

Folic acid supplementation: what is new? Fetal, obstetric, long-term benefits and risks

The association between folic acid supplementation, prior to conception and/or during pregnancy and pregnancy outcomes, has been the subject of numerous studies. The worldwide recommendation of folic acid is at least 0.4 mg daily for all women of reproductive age, and 4–5 mg in high-risk women. In addition, evidence shows that folic acid supplementation could modulate other adverse pregnancy outcomes, specifically, in pregnancies complicated by seizure disorders, preeclampsia, anemia, fetal growth restriction and autism. This review summarizes the available national and international guidelines, concerning the indications and dosage of folic acid supplementation during pregnancy. In addition, it describes the potential preventive benefits of folic acid supplementation on multiple maternal and fetal outcomes, as well as potential risks.

Customized versus Population Fetal Growth Norms and Adverse Outcomes Associated with Small for Gestational Age Infants in a High-Risk Cohort.

OBJECTIVE To compare population versus customized fetal growth norms in identifying neonates at risk for adverse perinatal and neonatal outcomes (AOs) associated with small for gestational age (SGA) in high-risk women. DESIGN Secondary analysis to a multicenter treatment trial of pregnant women at high risk for preeclampsia using low-dose aspirin versus placebo. The associations between SGA by population (SGApop) and customized (SGAcust) norms and AOs were evaluated. RESULTS A total of 2,289 mother/infant pairs were included in the analysis. The rates of SGA in the aspirin and placebo groups were similar by the customized (22.8% vs 23.9%; p = 0.55) or population (8.7% vs 7.5%; p = 0.54) norms; however, they were lower using population norms compared with customized norms (p < 0.001). SGAcust, but not SGApop, was associated with spontaneous preterm birth (odds ratio [OR]: 1.44, 95% confidence interval [CI]: 1.15-1.81; p < 0.001), preterm premature rupture of membranes (OR 1.42 95% CI 1.05-1.92; p = 0.02), and cesarean delivery (OR: 1.35, 95% CI: 1.11-1.64; p = 0.002). Both SGAcust and SGApop were associated with the composite neonatal outcome, indicated preterm delivery before 32, 35, and 37 weeks, oligohydramnios, fetal distress, as well as decreased risk of oxygen requirement. Neither was associated with preeclampsia. CONCLUSION Customized approach for assessment of fetal growth was associated with higher SGA rates and better identification of SGA neonates at risk for AOs.

Catastrophic antiphospholipid syndrome in pregnancy, a diagnosis that should not be missed

Abstract Catastrophic antiphospholipid syndrome (CAPS) is an accelerated form of the antiphospholipid antibody syndrome resulting in multi-organ ischemia and failure. It is a rare and life-threatening condition that can be easily mistaken with hemolysis elevated liver enzymes low platelets syndrome, thrombotic thrombocytopenic purpura, and hemolytic uremic syndrome. In order to make a diagnosis, it is required to have multi-organ thrombosis over 1 week affecting at least three organs or systems, and to have positive antiphospholipid antibody on two occasions (6 weeks apart), and histopathologic confirmation of small vessel occlusion. However, due to similarities in clinical and laboratory findings between CAPS and some other obstetric complications, potential misdiagnosis or delay in diagnosis are common, increasing the risk of adverse maternal and perinatal outcomes. In this review we summarized information presented in previous studies, focusing on CAPS related to pregnancy. We reviewed diagnostic criteria, differential diagnosis, and common presentation ranging from malaise, abdominal pain, dyspnea, hypertension, to altered mental status and seizures. We also discussed management in pregnancy and included a detailed algorithm with steps to take. Of note, the most significant reduction in mortality was seen in patients receiving triple therapy which will be discussed in this review.

Acute Myocardial Infarction Due to Coronary Artery Dissection in the Postpartum Period

Background Though rare, myocardial infarction secondary to coronary artery dissection is a life-threatening event. In reproductive age women, it commonly occurs during pregnancy or the postpartum period. Case We present a case of pregnancy-related acute myocardial infarction due to spontaneous coronary artery dissection in a 37-year-old woman who presented to the emergency room with shortness of breath and sudden onset of retrosternal chest pain 8 days after delivery of premature twins. Coronary artery catheterization showed 75 to 90% stenosis in the left main coronary artery (LMCA), extending into the proximal and mid left anterior descending (LAD) branch. The LMCA appearance in the heart catheterization was consistent with vasospasm, but it was not responsive to medical management. Subsequently, she underwent a second coronary artery catheterization and was found to have dissection requiring emergent coronary artery bypass graft × 3 in the LMCA, circumflex, and LAD that was followed by an uneventful recovery. Conclusion Early diagnosis and management of myocardial infarction due to coronary artery dissection in the peripartum period is crucial. This condition should be suspected in young reproductive age women, even in the setting of minimal risk factors. Angiography is required for diagnosis. Management should be individualized as it may include both invasive and noninvasive measures.

A Rapidly Growing Abdominal Mass: Desmoid Tumor in Pregnancy

Background Desmoid tumors are benign soft tissue tumors that locally invade adjacent tissue. There is a paucity of reports describing the rapid growth of these tumors during pregnancy. Case A giant desmoid tumor arising from the left abdominal wall of a young female patient with rapid growth during pregnancy is described. Preoperative evaluation included ultrasonography and magnetic resonance imaging. Decision made by a multidisciplinary team was not to intervene before birth, and abdominal delivery at term was accomplished. Conclusion Desmoid tumors should be part of the differential diagnosis in an abdominal wall tumor of rapid growth during pregnancy. Future studies are needed for better understanding of the pathogenesis, diagnosis, and treatment of desmoid tumors in pregnant women.

Treatment options for hypertension in pregnancy and puerperium

ABSTRACT Introduction: Hypertensive disorders have become increasingly prevalent and complicate an increasing number of pregnancies. Therefore it is essential that the medications used to treat these disorders be well understood. Furthermore the management is complicated by special consideration needed for the physiologic changes of pregnancy as well as the consideration for possible adverse fetal effects. Areas covered: We performed a review of the scientific literature of medications used to treat hypertensive disorders in pregnancy. We reviewed the guidelines used by different societies all over the world. We also discussed the pharmacodynamics, pharmacokinetics and possible adverse effects relating to the antihypertensive medications. Finally, we discussed the long-term maternal implications of these diseases. Expert opinion: Overall, we encourage a step-wise approach to treating hypertensive disorders of pregnancy. While making sure to max out the use of one medications prior to shifting to another. Also, it is imperative not to be aggressive with treatment due to risk of compromising utero-placental blood flow. There is research currently involving biomarkers, nano-medicine and the placenta project with hopes of developing new targeted medications with a good fetal safety profile.

Adverse Effect of High-Fat Diet on Metabolic Programming in Offspring Born to a Murine Model of Maternal Hypertension

BACKGROUND We previously reported that offspring heterozygous mice partially lacking endothelial nitric oxide synthase (eNOS) gene, and born to hypertensive eNOS-/- Knockout mother, are hypertensive. We hypothesized that those offspring when placed on high-fat diet (HFD) will undergo altered metabolic programming increasing their risk for developing metabolic syndrome. METHODS eNOS-/-KO and wild-type mice (eNOS+/+WT) were cross-bred to produce heterozygous offspring: maternal heterozygous (Mat, eNOS-/+), born from hypertensive eNOS-/-KO mothers; and paternal heterozygous (Pat, eNOS-/+), born from normotensive WT mothers. Mat, eNOS-/+ and Pat, eNOS-/+ female were allocated to HFD or control diet (CD) until 8 weeks of age. Then a metabolic profile was obtained: weight, glucose/insulin tolerance test (GTT, ITT), systolic blood pressure (SBP), serum fasting levels of insulin, adiponectin, leptin, and a lipid panel. RESULTS Weight was not different between all offspring within each diet. GTT curve was higher in Mat, eNOS-/+ vs. Pat, eNOS-/+ offspring on both diet (P < 0.001). In ITT, glucose level at 15 minutes was higher in Mat, eNOS-/+ on HFD. Insulin level was increased in Mat, eNOS-/+ vs. Pat, eNOS-/+ on either diet. SBP was elevated in Mat, eNOS-/+ vs. Pat, eNOS-/+ on CD and was further raised in Mat, eNOS-/+ offspring on HFD (P < 0.001). No other differences were seen except for lower high-density lipoprotein levels in Mat, eNOS-/+ fed HFD (P < 0.003). CONCLUSIONS Mat, eNOS-/+ offspring exposed in utero to maternal hypertension and fed HFD postnatally have increased susceptibility for metabolic abnormalities. Thus, maternal HTN is a risk factor for altered fetal metabolic programming.
