Objectives: The effects of lipid metabolism disorders (LMD) on pregnancy outcomes is not well known. The purpose of this study is to evaluate the impact of LMD on maternal and fetal outcomes., Methods: Using the Healthcare Cost and Utilization Project - National Inpatient Sample from the United States, we carried out a retrospective cohort study of all births between 1999 and 2015 to determine the risks of complications in pregnant women known to have LMDs. All pregnant patients diagnosed with LMDs between 1999 and 2015 were identified using the International Classification of Disease-9 coding, which included all patients with pure hypercholesterolemia, pure hyperglyceridemia, mixed hyperlipidemia, hyperchylomicronemia, and other lipid metabolism disorders. Adjusted effects of LMDs on maternal and newborn outcomes were estimated using unconditional logistic regression analysis., Results: A total of 13,792,544 births were included, 9,666 of which had an underlying diagnosis of LMDs for an overall prevalence of 7.0 per 10,000 births. Women with LMDs were more likely to have pregnancies complicated by diabetes, hypertension, and premature births, and to experience myocardial infarctions, venous thromboembolisms, postpartum hemorrhage, and maternal death. Their infants were at increased risk of congenital anomalies, fetal growth restriction, and fetal demise., Conclusions: Women with LMDs are at significantly higher risk of adverse maternal and newborn outcomes. Prenatal counselling should take into consideration these risks and antenatal care in specialized centres should be considered., (© 2021 Walter de Gruyter GmbH, Berlin/Boston.)

A study published in the journal Paediatric & Perinatal Epidemiology explores the association between hypertensive disorders of pregnancy (HDP) and cardiovascular mortality. The study found that specific subtypes of HDP, such as chronic hypertension, preeclampsia with severe features, and eclampsia, were associated with an increased risk of cardiovascular-related deaths. However, the study may have underestimated the true association due to limitations in data collection and classification of cardiovascular events. The findings highlight the need for extended postpartum care and health insurance coverage for individuals with HDP to prevent maternal cardiovascular deaths. Further research is needed to validate the underlying causes of maternal mortality and improve the quality of epidemiological data for surveillance purposes. [Extracted from the article]

Aims Hypertensive disorders of pregnancy (HDP) occur in 10% of pregnancies in the general population, pre-eclampsia specifically in 3–5%. Hypertensive disorders of pregnancy may have a high prevalence in, and be poorly tolerated by, women with heart disease. Methods and results The prevalence and outcomes of HDP (chronic hypertension, gestational hypertension or pre-eclampsia) were assessed in the ESC EORP ROPAC (n  = 5739), a worldwide prospective registry of pregnancies in women with heart disease. The overall prevalence of HDP was 10.3%, made up of chronic hypertension (5.9%), gestational hypertension (1.3%), and pre-eclampsia (3%), with significant differences between the types of underlying heart disease (P  < 0.05). Pre-eclampsia rates were highest in women with pulmonary arterial hypertension (PAH) (11.1%), cardiomyopathy (CMP) (7.1%), and ischaemic heart disease (IHD) (6.3%). Maternal mortality was 1.4 and 0.6% in women with vs. without HDP (P  = 0.04), and even 3.5% in those with pre-eclampsia. All pre-eclampsia-related deaths were post-partum and 50% were due to heart failure. Heart failure occurred in 18.5 vs. 10.6% of women with vs. without HDP (P  < 0.001) and in 29.1% of those with pre-eclampsia. Perinatal mortality was 3.1 vs. 1.7% in women with vs. without HDP (P  = 0.019) and 4.7% in those with pre-eclampsia. Conclusion Hypertensive disorders of pregnancy and pre-eclampsia rates were higher in women with CMP, IHD, and PAH than in the general population. Adverse outcomes were increased in women with HDP, and maternal mortality was strikingly high in women with pre-eclampsia. The combination of HDP and heart disease should prompt close surveillance in a multidisciplinary context and the diagnosis of pre-eclampsia requires hospital admission and continued monitoring during the post-partum period.

Background The prevalence of non-communicable diseases (NCDs) is rising in low and middle-income countries (LMIC). We aimed to report on the prevalence of NCDs in pregnancy and their associated perinatal outcomes in a regional hospital in Haiti. Methods We conducted the "Diabète et hYpertension Artéerielle et leurs issues MAternelles et Néonatales" (DYAMAN) prospective cohort study in a regional hospital in Haiti. Pregnant women presenting to care at 24-28 weeks were screened and treated for diabetes (DM) and hypertensive disorders of pregnancy (HDP) using setting-adapted protocols. Prevalence of NCDs and associated maternal-neonatal outcomes were described. Results 715 women were included, of which 51 (7.1%) had DM, 90 (12.6%) had HDP, and 30 (4.2%) had both DM and HDP (DM/HDP). Of 422 (59%) women delivered in hospital, 58 (13.7%) had preeclampsia, including 5 (8.6%) with eclampsia. Preterm birth <32 weeks was more common in the HDP than the control, DM, and DM/HDP groups. More low birth weight babies (n = 20, 25.6%) were born to the HDP group than to the control (n = 20, 7.1%), DM (n = 1, 2.7%), and DM/ HDP (n = 3, 12%) groups (P < 0.001). Macrosomia and hypoglycemia affected 5 (8%) neonates of women with DM. Perinatal mortality, affecting 36/1000 births, was mainly driven by maternal NCDs. Conclusions NCDs in pregnancy led to adverse maternal and perinatal outcomes. This study will help to prepare future refinements aimed at optimizing the management of NCDs in pregnancy in LMIC. Research is required to understand barriers to patient attendance at antenatal follow-up, treatment escalation for hyperglycemia, and in-hospital delivery. [ABSTRACT FROM AUTHOR]

Those who are infected with Severe Acute Respiratory Syndrome-related CoronaVirus-2 are theoretically at increased risk of venous thromboembolism during self-isolation if they have reduced mobility or are dehydrated. Should patients develop coronavirus disease (COVID-19) pneumonia requiring hospital admission for treatment of hypoxia, the risk for thromboembolic complications increases greatly. These thromboembolic events are the result of at least two distinct mechanisms - microvascular thrombosis in the pulmonary system (immunothrombosis) and hospital-associated venous thromboembolism. Since pregnancy is a prothrombotic state, there is concern regarding the potentially increased risk of thrombotic complications among pregnant women with COVID-19. To date, however, pregnant women do not appear to have a substantially increased risk of thrombotic complications related to COVID-19. Nevertheless, several organizations have vigilantly issued pregnancy-specific guidelines for thromboprophylaxis in COVID-19. Discrepancies between these guidelines reflect the altruistic wish to protect patients and lack of high-quality evidence available to inform clinical practice. Low molecular weight heparin (LMWH) is the drug of choice for thromboprophylaxis in pregnant women with COVID-19. However, its utility in non-pregnant patients is only established against venous thromboembolism, as LMWH may have little or no effect on immunothrombosis. Decisions about initiation and duration of prophylactic anticoagulation in the context of pregnancy and COVID-19 must take into consideration disease severity, outpatient vs inpatient status, temporal relation between disease occurrence and timing of childbirth, and the underlying prothrombotic risk conferred by additional comorbidities. There is currently no evidence to recommend the use of intermediate or therapeutic doses of LMWH in thromboprophylaxis, which may increase bleeding risk without reducing thrombotic risk in pregnant patients with COVID-19. Likewise, there is no evidence to comment on the role of low-dose aspirin in thromboprophylaxis or of anti-cytokine and antiviral agents in preventing immunothrombosis. These unanswered questions are being studied within the context of clinical trials. [ABSTRACT FROM AUTHOR]

Fetal tachycardia is a rare complication during pregnancy. After exclusion of maternal and fetal conditions that can result in a secondary fetal tachycardia, supraventricular tachycardia is the most common cause of a primary sustained fetal tachyarrhythmia. In cases of sustained fetal supraventricular tachycardia, maternal administration of digoxin, flecainide, sotalol, and more rarely amiodarone, is considered. As these medications have the potential to cause significant adverse effects, we sought to examine maternal safety during transplacental treatment of fetal supraventricular tachycardia. In this narrative review we summarize the literature addressing pharmacologic properties, monitoring, and adverse reactions associated with medications most commonly prescribed for transplacental therapy of fetal supraventricular tachycardia. We also describe maternal monitoring practices and adverse events currently reported in the literature. In light of our findings, we provide clinicians with a suggested maternal monitoring protocol aimed at optimizing safety. [ABSTRACT FROM AUTHOR]

Severe maternal morbidity is a composite indicator of maternal health and obstetrical care. Little is known about the risk of recurrent severe maternal morbidity in a subsequent delivery. This study aimed to estimate the risk of recurrent severe maternal morbidity in the next delivery after a complicated first delivery. We analyzed a population-based cohort study of women with at least 2 singleton hospital deliveries between 1989 and 2021 in Quebec, Canada. The exposure was severe maternal morbidity in the first hospital-recorded delivery. The study outcome was severe maternal morbidity at the second delivery. Log-binomial regression models adjusted for maternal and pregnancy characteristics were used to generate relative risks and 95% confidence intervals comparing women with and without severe maternal morbidity at first delivery. Among 819,375 women, 43,501 (3.2%) experienced severe maternal morbidity in the first delivery. The rate of severe maternal morbidity recurrence at second delivery was 65.2 vs 20.3 per 1000 in women with and without previous severe maternal morbidity (adjusted relative risk, 3.11; 95% confidence interval, 2.96–3.27). The adjusted relative risk for recurrence of severe maternal morbidity was greatest among women who had ≥3 different types of severe maternal morbidity at their first delivery, relative to those with none (adjusted relative risk, 5.50; 95% confidence interval, 4.26–7.10). Women with cardiac complication at first delivery had the highest risk of severe maternal morbidity in the next delivery. Women who experience severe maternal morbidity have a relatively high risk of recurrent morbidity in the subsequent pregnancy. In women with severe maternal morbidity, these study findings have implications for prepregnancy counseling and maternity care in the next pregnancy. [Display omitted] [ABSTRACT FROM AUTHOR]
