Cardiac Risk Score to Predict Small for Gestational Age Infants in Pregnant Women With Heart Disease.

BACKGROUND: One of the most common fetal complications in pregnant women with cardiovascular disease is a small for gestational age (SGA) neonate, which is associated with a higher risk of perinatal morbidity/mortality and poor long-term health outcomes. The objective of this study was to identify cardiac determinants and derive a risk score for clinically relevant SGA < 5th percentile (SGA-5th). METHODS: A prospective cohort of 1812 pregnancies in women with heart disease were studied. SGA-5th was the outcome of interest, defined as birth weight < 5th percentile for gestational age and sex. Multivariable logistic regression analysis was used to identify predictors for SGA-5th. Based on the regression coefficients, a weighted risk score was created. RESULTS: SGA-5th complicated 10% of pregnancies, 11 predictors of SGA-5th were identified, and each was assigned a weighted score: maternal cyanosis (8), Fontan palliation (7), smoking (3), moderate or severe valvular regurgitation (3), ß-blocker use throughout pregnancy (4) or only in the 2nd and 3rd trimesters (2), high baseline ß-blocker dose (4), body mass index < 18.5 kg/m2 (3) or 18.5-24.9 kg/m2 (1), Asian/other ethnicity (2), and significant outflow tract obstruction (1). In the absence of these identified risk factors, the risk of SGA-5th was approximately 4%. Pregnancies with risk scores of 1 had a rate of 5%; 2, 7%; 3, 9%; 4, 12%; 5, 14%; 6, 18%; 7, 23%; 8, 28%; and ≥ 9, 34%. CONCLUSIONS: There are a number of cardiac predictors that are associated with increased risk of SGA-5th. This is a prognostically important outcome, and consideration should be given to routinely predicting and modifying the risk whenever possible.

Myasthenia Gravis and Pregnancy: Toronto Specialty Center Experience.

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disorder that frequently affects young women of reproductive age. The multidirectional interplay between MG, pregnancy, and fetal health poses a complex scenario for pregnant women with MG and the healthcare team. Here, we reviewed our local experience with MG, pregnancy, and outcomes. METHODS: We performed a retrospective chart review of patients with MG attending the Prosserman Family Neuromuscular Clinic from 2001 to 2019 and who were referred to a high-risk pregnancy clinic. MG status was defined as stable, better, or worse. Information was collected on the delivery route, pregnancy, and neonatal complications. RESULTS: We identified 20 women with MG for a total of 28 pregnancies. Worsening was observed in 50% of pregnancies: 18% during pregnancy, 25% following delivery, and 7% during both. 66.7% of patients with MG duration of 2 years or less had worsening during pregnancy. Three patients who stopped immunosuppressive treatment during pregnancy worsened and one had a crisis. C-section was done in 29% of pregnancies. The rate of delivery complications was 7% and of neonatal MG was 7%. CONCLUSION: A high proportion of MG patients worsened during pregnancy, particularly those with disease duration less than 2 years, and those who discontinued immunosuppression during pregnancy. However, pregnancy was largely unaffected, rate of neonatal MG was low, frequencies of C-section, delivery complications, and premature births were similar to the general population. While the study has limitations due to the retrospective nature, these insights provide some guidance when counseling young myasthenic women about family planning.

Guideline No. 393-Diabetes in Pregnancy.

OBJECTIVES: This guideline reviews the evidence relating to the diagnosis and obstetrical management of diabetes in pregnancy. OUTCOMES: The outcomes evaluated were short and long-term maternal outcomes including pre-eclampsia, Caesarean section, future diabetes and other cardiovascular complications; and fetal outcomes including congenital anomalies, stillbirth, macrosomia, birth trauma, hypoglycemia and long-term effects. EVIDENCE: Published literature was retrieved through searches of PubMed and The Cochrane Library using appropriate controlled vocabulary (MeSH terms "diabetes" and "pregnancy"). Where appropriate, results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date limits but results were limited to English or French language materials. VALUES: The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care. SUMMARY STATEMENTS: RECOMMENDATIONS.

Hyperreactio Luteinalis: Maternal and Fetal Effects.

Hyperreactio luteinalis is a rare condition in which there is massive cystic enlargement of the ovaries, mimicking malignancy, during pregnancy. When confronted with this condition, the fear of missing a cancer diagnosis often leads the physician to react with unnecessary surgical intervention, potentially resulting in impaired future fertility. The literature on the subject contains mainly case reports and one small case series. A recent review attempted to summarize what is currently known, but there has not yet been a pervasive change in the approach to the management of this condition. In order to define the natural history of the condition and its maternal and fetal effects, we examined all case reports available in the English literature from 1993 to 2014, in addition to another as yet unpublished case report. Our analysis suggests that, despite its impressive presentation with ovarian enlargement and hyperandrogenism, hyperreactio luteinalis tends to be self-limiting, with spontaneous postpartum resolution and without untoward maternal or fetal sequelae. In particular, fetal virilization is rare, and dependent on the timing of hyperandrogenism. Adverse pregnancy outcomes are likely a consequence of the abnormally high hCG levels observed in many of these gestations, and the subset of women with these abnormal values should be considered for enhanced surveillance. Vaginal delivery is preferred, and strategies to sustain the potential for breastfeeding must be introduced while maternal androgen levels fall, allowing lactation to be established. Considering its benign nature and postpartum resolution, management of HL must be conservative, and continued education of health care professionals who may encounter this entity is vital.

L'hyperreactio luteinalis est un trouble rare qui donne lieu à une hypertrophie kystique des ovaires de grande envergure, laquelle imite la présence d'une tumeur maligne, pendant la grossesse. La présence d'une telle situation mène souvent le médecin à procéder inutilement à une intervention chirurgicale motivée par la crainte de voir un diagnostic de cancer passer inaperçu, ce qui pourrait affecter la fertilité future de la patiente. La littérature sur le sujet consiste principalement en des exposés de cas et en une série de cas de faible envergure. Bien qu'une récente analyse ait tenté de résumer les données connues à ce sujet à l'heure actuelle, aucune modification n'a encore été universellement apportée à la prise en charge de cette pathologie. Afin de définir l'histoire naturelle de cette dernière et d'en déterminer les effets maternels et fœtaux, nous nous sommes penchés sur tous les exposés de cas ayant été publiés en anglais entre 1993 et 2014, ainsi que sur un exposé de cas n'ayant pas encore été publié. Notre analyse laisse entendre que, malgré sa présentation spectaculaire (hypertrophie ovarienne et hyperandrogénie), l'hyperreactio luteinalis a tendance à être spontanément résolutive à la suite de l'accouchement, sans séquelles indésirables pour la mère ou le fœtus. En particulier, la virilisation fœtale est rare et dépend de la chronologie de l'hyperandrogénie. Les issues de grossesse indésirables sont probablement attribuables aux taux anormalement élevés de hCG qui sont constatés dans bon nombre des grossesses affectées; la mise en œuvre d'une surveillance accrue devrait être envisagée pour ce qui est du sous-groupe des femmes qui présentent de telles valeurs anormales. L'accouchement vaginal est à privilégier et des stratégies visant à soutenir le potentiel d'allaitement doivent être mises en œuvre pendant la chute des taux maternels d'androgènes, afin de permettre la lactation. Compte tenu de la nature bénigne de l'hyperreactio luteinalis et de sa résolution postpartum, la prise en charge de ce trouble doit être conservatrice; de plus, la formation continue des professionnels de la santé qui pourraient devoir y faire face est cruciale.

Pheochromocytoma in a Pregnant Woman With Prior Traumatic Aortic Injury.

BACKGROUND: Pheochromocytoma, a catecholamine-producing tumor seldom encountered in pregnancy, is often heralded by nonspecific symptoms and undue mortality with delayed diagnosis. The presence of an aortic pseudoaneurysm poses a management challenge given the risk of aortic rupture amplified by hypertensive events. CASE: A 30-year-old woman, gravida 3 para 1, presented at 23 6/7 weeks of gestation with vomiting, chest pain, and severe hypertension. Investigation revealed adrenal pheochromocytoma and pseudoaneurysm at the site of a previous aortic injury. Prazosin and phenoxybenzamine achieved α-blockade with subsequent addition of labetalol for ß-blockade. Concerns for aortic dissection led to endovascular aortic repair at 30 2/7 weeks of gestation. A female neonate was delivered by urgent cesarean delivery for persistent postprocedure fetal bradycardia. An adrenalectomy followed with near-immediate symptom resolution. Mother and neonate remain well. CONCLUSION: The case underscores the necessity of a meticulous approach to hypertension management and the pivotal role of diligent multidisciplinary collaboration to achieve a safe outcome.

Pregnancy in women with congenital heart disease.

Due to advances in paediatric congenital heart surgery, there are a growing number of women with congenital heart disease (CHD) reaching childbearing age. Pregnancy, however, is associated with haemodynamic stresses which can result in cardiac decompensation in women with CHD. Many women with CHD are aware of their cardiac condition prior to pregnancy, and preconception counselling is an important aspect of their care. Preconception counselling allows women to make informed pregnancy decisions, provides an opportunity for modifications of teratogenic medications and, when necessary, repair of cardiac lesions prior to pregnancy. Less commonly, the haemodynamic changes of pregnancy unmask a previously unrecognised heart lesion. In general, pregnancy outcomes are favourable for women with CHD, but there are some cardiac lesions that carry high risk for both the mother and the baby, and this group of women require care by an experienced multidisciplinary team. This review discusses preconception counselling including contraception, an approach to risk stratification and management recommendations in women with some common CHDs.

Pregnancy outcomes in women with spinal cord lesions.

OBJECTIVE: Women with spinal cord lesions present special challenges during pregnancy. We studied their pregnancy outcomes with regard to medical, obstetrical, and social concerns. METHODS: We reviewed the records of pregnant women with spinal cord injury who attended our institution between 1999 and 2009. RESULTS: Thirty-two women with a total of 37 pregnancies were identified. Most were nulliparous (65%) with either thoracic or lumbar spinal cord lesions due to neural tube defects (69%), trauma (19%), tumours (9%), or iatrogenic injury (3%). Most had undergone orthopedic surgery (63%) or neurosurgery (53%). The most common medical conditions were neurogenic bladder (53%), anemia (16%), autonomic hyperreflexia (9%), and elevated BMI > 30 (6%). Recurrent urinary tract infection occurred in 32%. Antibiotic suppression against bacteriuria was used in 35%. Antenatal hospitalization occurred in 46%, most often because of threatened preterm labour (19%). There were 33 live births and two stillbirths (6%). Preterm birth < 37 weeks occurred in 24%. Vaginal birth occurred in 33%. CONCLUSION: Pregnant women with spinal cord lesions generally have successful pregnancy outcomes. However, their pregnancies are at significant risk for preterm birth, infection, and Caesarean section. Coordinated multidisciplinary care is recommended for optimal management of these pregnancies.

Comparison of National Diabetes Data Group and American Diabetes Association diagnostic criteria for gestational diabetes in their identification of postpartum risk of glucose intolerance.

AIMS: Gestational diabetes mellitus (GDM) is associated with adverse obstetrical outcomes and postpartum pre-diabetes/diabetes. As the American Diabetes Association (ADA) criteria for GDM may capture obstetrical risk better than the National Diabetes Data Group (NDDG) criteria, we compared these criteria in their detection of postpartum risk of glucose intolerance. METHODS: 487 Women underwent oral glucose tolerance test in pregnancy and at 3-month postpartum. Participants were stratified into the following 5 groups: normal glucose tolerance (NGT) by both ADA and NDDG; gestational impaired glucose tolerance (GIGT) by ADA only; GIGT by both ADA and NDDG; GDM by ADA only; and GDM by both ADA and NDDG. RESULTS: The prevalence of postpartum glucose intolerance (pre-diabetes/diabetes) varied across the groups (NGT by both ADA and NDDG: 5.9%; GIGT by ADA only: 14.3%; GIGT by both ADA and NDDG: 10.6%; GDM by ADA only: 21.6%; GDM by both ADA and NDDG: 32.8%; overall p<0.0001). Importantly, however, for predicting postpartum pre-diabetes/diabetes, abnormal antepartum glucose tolerance by NDDG and ADA, respectively, exhibited comparable positive predictive value (26% vs. 24%) and area-under-the-receiver-operating-characteristic-curve (0.67 vs. 0.66, p=0.63). CONCLUSIONS: Unlike with obstetrical outcomes, NDDG and ADA criteria for GDM are similar in their ability to identify postpartum metabolic risk.

Obstetric outcomes of women with intracranial neoplasms.

OBJECTIVE: To determine the obstetric outcomes of women diagnosed with a primary intracranial neoplasm prior to or during pregnancy and the puerperium. METHODS: Demographic data, neurologic, obstetric, and neonatal outcomes were extracted retrospectively from charts identified from two hospital databases. RESULTS: Twenty-two patients with 25 pregnancies were identified. Thirteen patients were diagnosed prior to pregnancy (group 1); tumor growth or recurrence during pregnancy occurred in 3 patients. Nine patients were diagnosed during pregnancy and the puerperium (group 2); 7 underwent neurosurgery at a mean gestational age of 27+/-5.7 weeks; 2 experienced permanent visual loss. Significantly more gliomas occurred in group 1, but there were significantly more meningiomas in group 2. Numbers of cesarean delivery, preterm delivery at less than 34 weeks, and NICU admission were higher in group 2 than group 1, but this was not statistically significant. CONCLUSION: Although not statistically significant, neurologic deterioration during pregnancy may be associated with cesarean delivery, preterm delivery, and NICU admission.

A randomised controlled trial of biopsy forceps and cannula aspiration for transcervical chorionic villus sampling.

OBJECTIVE: This trial compared two instruments for transcervical chorionic villus sampling (CVS). DESIGN: Randomised controlled trial. SETTING: Regional university prenatal diagnosis and treatment centre. POPULATION: Two hundred women were randomised at 10(+0)-12(+6) weeks of gestation to transcervical CVS using cannula aspiration (CA) or biopsy forceps (BF). METHODS: Women undergoing indicated CVS signed informed consent. Randomisation after decision to perform transcervical CVS. PRIMARY OUTCOME: the rise in maternal serum alpha-fetoprotein (alpha-FP). SECONDARY OUTCOMES: (i) placental trauma (fetomaternal haemorrhage [FMH]); (ii) laboratory, procedure, and cytogenetic results and pregnancy outcomes; (iii) patient and operator satisfaction; and (iv) economic analyses. Analyses were performed by intention to treat. RESULTS: The -FP rise did not differ between groups; there was no other evidence of placental trauma. BF were better tolerated by women, provided culturable tissue, after fewer instrument passes, with greater ease and in less time. BF were associated with cost savings. CONCLUSIONS: Unlike -FP, other markers of FMH were unaltered, questioning the reliability of alpha-FP as an indicator of FMH. Compared with CA, transcervical BF caused comparable placental trauma, appeared to be similarly effective and safe and were preferred by operators and patients.

Spontaneous dissection of the left main coronary artery.

Spontaneous coronary artery dissection remains a rare but important cause of acute coronary syndromes. Presentation depends on the extent of the dissection, the vessels involved and the rate of its development, and can encompass the entire spectrum of coronary syndromes, with some patients being asymptomatic and others presenting with angina, non-ST segment elevation myocardial infarction, ST-elevation myocardial infarction and sudden cardiac death. The authors describe a 33-year-old pregnant woman who presented with a non-ST segment elevation myocardial infarction secondary to a spontaneous dissection of the left main coronary artery.

C-reactive protein and gestational diabetes: the central role of maternal obesity.

Acute-phase biomarkers such as C-reactive protein (CRP) and IL-6 have emerged as predictors of incident type 2 diabetes mellitus, implicating chronic subclinical inflammation as a factor in the pathophysiology of diabetes. Gestational diabetes (GDM) identifies a population of women at high risk of subsequent type 2 diabetes mellitus, representing an early stage in the natural history of the disease. In this context, we performed a cross-sectional study to determine whether markers of subclinical inflammation are elevated in patients with GDM. We studied 180 healthy pregnant women undergoing oral glucose tolerance testing in the late second or early third trimester. Based on oral glucose tolerance testing and prepregnancy body mass index (BMI), participants were stratified into four groups: 1) normal glucose tolerance (NGT) lean (BMI, <25 kg/m(2)) (n = 65); 2) NGT overweight (n = 28); 3) impaired glucose tolerance (n = 39); and 4) GDM (n = 48). Median CRP level was highest in overweight NGT subjects (8.8 mg/liter), followed by GDM (5.5 mg/liter), impaired glucose tolerance (4.4 mg/liter), and lean NGT (4.4 mg/liter) (overall P = 0.0297). CRP was significantly correlated with prepregnancy BMI (r = 0.38, P < 0.0001), followed by fasting insulin (r = 0.27, P = 0.0002) and fasting blood glucose (r = 0.18, P = 0.016). In multivariate linear regression analysis, prepregnancy BMI emerged as the most important determinant of CRP concentration, whereas glycemic tolerance status was not a significant factor. Furthermore, the observed stepwise increase in CRP per tertile of prepregnancy BMI was not significantly attenuated by glycemic tolerance status or factors known to be associated with GDM. In summary, we demonstrate that maternal serum levels of CRP are not related to GDM but rather correlate significantly with prepregnancy obesity. An independent contribution of CRP to risk of GDM could not be confirmed. These data suggest a model in which obesity mediates a systemic inflammatory response, with possible downstream metabolic sequelae, including insulin resistance and glucose dysregulation.
