Abstract
BACKGROUND Maternal substance use can pose a risk to the fetal health. We studied the background characteristics of women with substance use disorders (SUDs) and selected neonatal outcomes in their children. MATERIAL AND METHODS A database-linkage study was performed. The sample consisted of pregnant women with a SUD during pregnancy (ICD-10 diagnosis F10-F19 except F17, n = 1710), women not diagnosed with a SUD (n = 1,511,310) in Czechia in 2000-2014, and their children. The monitored neonatal outcomes were gestational age, birth weight, preterm birth, and small-for-gestational age (SGA). Binary logistic regression adjusted for age, marital status, education, concurrent substance use, and prenatal care was performed. RESULTS Women with illicit SUDs were younger, more often unmarried, with a lower level of education, a higher abortion rate, a higher smoking rate, and lower compliance to prenatal care than women with a SUD related to alcohol, or sedatives and hypnotics (SH). Women with a SUD had worse socioeconomic situations, poorer pregnancy care, and worse neonatal outcomes than women without a SUD. After adjustment, we found no difference in SGA between the illicit SUD groups and the alcohol and the SH groups. The newborns from all SUD groups had a higher risk of SGA when compared to women without a SUD. However after adjustment, the difference remained significant just in the alcohol group (OR = 1.9, 95 % CI = 1.4-2.6). CONCLUSION Mother's SUD during pregnancy increased risk of fetal growth restriction as measured by SGA. The role of maternal socioeconomic and lifestyle factors for the risk of SGA was substantial.

Abstract
BACKGROUND Pain during pregnancy is common, and its management is complex. Certain analgesics may increase the risk for adverse fetal and pregnancy outcomes, while poorly managed pain can result in adverse maternal outcomes such as depression and hypertension. Guidelines to assist clinicians in assessing risks and benefits of exposure to analgesics for the mother and unborn infant are lacking, necessitating evidence-based recommendations for managing pain in pregnancy. METHODS A comprehensive literature search was conducted to assess pregnancy safety data for pharmacological and nonpharmacological pain management methods. Relevant clinical trials and observational studies were identified using multiple medical databases, and included studies were evaluated for quality and possible biases. RESULTS Paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) are appropriate for mild to moderate pain, but NSAIDs should be avoided in the third trimester due to established risks. Short courses of weaker opioids are generally safe in pregnancy, although neonatal abstinence syndrome must be monitored following third trimester exposure. Limited safety data for pregabalin and gabapentin indicate that these are unlikely to be major teratogens, and tricyclic antidepressants and serotonin-norepinephrine reuptake inhibitors have limited but overall reassuring safety data. Many of the included studies were limited by methodological issues. CONCLUSIONS Findings from this review can guide clinicians in their decision to prescribe analgesics for pregnant women. Treatment should be tailored to the lowest therapeutic dose and shortest possible duration, and management should involve a discussion of risks and benefits and monitoring for response. Further research is required to better understand the safety profile of various analgesics in pregnancy.

Abstract
The purpose of this study was to explore the association between colds, depressive symptoms during pregnancy and offspring congenital heart disease (CHD). A 1:2 matching case-control study was conducted in Northwest China. Information was gathered by a structured questionnaire and was reviewed by investigators on the spot. Multivariate logistic regressions and nonlinear mixed effect model were performed. 614 cases and 1228 controls were available in this study. After adjusting for potential confounders, the colds during the entire pregnancy were associated with increased risk of offspring CHD (OR = 1.44(1.12-1.85)). Similarly, there was a higher depression score in CHD group than the control group (OR = 1.89(1.48-2.41)). In addition, the women with both colds and higher depression scores had a higher risk of offspring CHD (OR = 2.72(1.87-3.93)) than their counterparts with only colds (OR = 1.48(1.04-2.09)) or with only higher depression scores (OR = 1.94(1.37-2.74)). The combined effects were significant in the multiplication model (OR = 2.04(1.47-2.83)) but not in the additive model (S = 1.40(0.70-2.81), AP = 0.19(-0.15-0.53) and RERI = 0.55(-0.54-1.64)). In conclusion, the colds and depressive symptoms during pregnancy were found associated with increased risk of offspring CHD and we found for the first time that there existed a statistically multiplying interaction effect of colds and depression on increasing risk of offspring CHD.

Abstract
Licit and illicit drug use in pregnant women constitutes a long lasting and serious problem worldwide. Information on long-term effects of maternal drug use on the child is limited. Nationwide registers provide a great potential to study short and long-term consequences for children exposed to licit and illicit drugs during pregnancy. We discuss this potential, with a special emphasis on exposure to methamphetamine, heroin and prescription drugs used for opioid maintenance treatment (OMT). We also discuss the advantages of register data and of merging such data from different regions. The Czech and Scandinavian registers are largely comparable and provide great opportunities to conduct innovative research. For instance, using Czech and Scandinavian cohorts we can compare groups with similar characteristics, such as mothers in OMT and mothers addicted to other drugs while also controlling for important confounding factors such as health and socio-economic status.

Abstract
The use of aspirin and other NSAIDs during the first trimester of pregnancy is widespread, despite inconclusive evidence regarding the possible risks for the baby. We present an overview of the current evidence relating to the associations between aspirin or NSAID use during the first trimester of pregnancy and the risk of congenital malformations. We systematically searched Medline, Embase, the Cochrane Library and the reference lists of all relevant articles from 1966 to March 2008 that examined the association between aspirin and NSAID use during the first trimester of pregnancy and the risk of congenital malformations in humans. We analyzed 30 studies that met the predefined inclusion criteria: 22 case-control studies, seven cohort studies and one randomized, controlled trial. There are not enough human data available to assess the effect of high-dose aspirin and NSAIDs in pregnant women, such as those used in the treatment of rheumatoid arthritis, osteoarthritis and pain relief. This review suggests that the exposure to aspirin or NSAIDs during the first trimester of pregnancy is associated with an increased risk of gastroschisis (aspirin), cardiac malformations (NSAIDs) and orofacial malformations (naproxen).

Abstract
Advances have been made in identifying genetic etiologies of congenital heart defects. Through this knowledge, preventive strategies have been designed and instituted, and prospective parents are counseled regarding their risk of having an affected child. Great strides have been made in genetic variant identification, and genetic susceptibility to environmental exposures has been hypothesized as an etiology for congenital heart defects. Unfortunately, similar advances in understanding have not been made regarding strategies to prevent nongenetic risk factors. Less information is available regarding the potential adverse effect of modifiable risk factors on the fetal heart. This review summarizes the available literature on these modifiable exposures that may alter the risk for congenital heart disease. Information regarding paternal characteristics and conditions, maternal therapeutic drug exposures, parental nontherapeutic drug exposures, and parental environmental exposures are presented. Factors are presented in terms of risk for congenital heart defects as a group. These factors also are broken down by specific defect type. Although additional investigations are needed in this area, many of the discussed risk factors present an opportunity for prevention of potential disease.

Abstract
Previous studies suggested that early pregnancy exposure to specific oral decongestants increases the risks of several birth defects. Using January 1993-January 2010 data from the Slone Epidemiology Center Birth Defects Study, we tested those hypotheses among 12,734 infants with malformations (cases) and 7,606 nonmalformed control infants in the United States and Canada. Adjusted odds ratios and 95% confidence intervals were estimated for specific birth defects, with controlling for potential confounders. Findings did not replicate several hypotheses but did support 3 previously reported associations: phenylephrine and endocardial cushion defect (odds ratio = 8.0; 95% confidence interval: 2.5, 25.3; 4 exposed cases), phenylpropanolamine and ear defects (odds ratio = 7.8; 95% confidence interval: 2.2, 27.2; 4 exposed cases), and phenylpropanolamine and pyloric stenosis (odds ratio = 3.2; 95% confidence interval: 1.1, 8.8; 6 exposed cases). Hypothesis-generating analyses involving multiple comparisons identified a small number of associations with oral and intranasal decongestants. Accumulating evidence supports associations between first-trimester use of specific oral and possibly intranasal decongestants and the risk of some infrequent specific birth defects.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin, which are available as "over-the counter" medications in most countries, are widely used by both pregnant and lactating women. They are popular non-opioid analgesics for the treatment of pain after vaginal and operative delivery. In addition, NSAIDs are used for tocolysis in premature labor, and low-dose aspirin has a role in the prevention of preeclampsia and recurrent miscarriage in antiphospholipid syndrome. NSAIDs and aspirin may affect fertility and increase the risk of early pregnancy loss. In the second trimester their use is considered reasonably safe, but has been associated with fetal cryptorchism. In the third trimester, NSAIDs and aspirin are usually avoided because of significant fetal risks such as renal injury, oligohydramnios, constriction of the ductus arteriosus (with potential for persistent pulmonary hypertension in the newborn), necrotizing enterocolitis, and intracranial hemorrhage. Maternal administration or ingestion of most NSAIDs results in low infant exposure via breastmilk, such that both cyclooxygenase-1 and cyclooxygenase-2 inhibitors are generally considered safe, and preferable to aspirin, when breastfeeding.

Abstract
Background Since use of non-steroidal anti-inflammatory drugs (NSAIDs) during pregnancy is common, small increases in the risk of birth defects may have significant implications for public health. Results of human studies on the teratogenic risks of NSAIDs are inconsistent. Therefore, we evaluated the risk of selected birth defects after prenatal exposure to prescribed and over-the-counter NSAIDs. Methods and Findings We used data on 69,929 women enrolled in the Norwegian Mother and Child Cohort Study between 1999 and 2006. Data on NSAID exposure were available from a self-administered questionnaire completed around gestational week 17. Information on pregnancy outcome was obtained from the Medical Birth Registry of Norway. Only birth defects suspected to be associated with NSAID exposure based upon proposed teratogenic mechanisms and previous studies were included in the multivariable logistic regression analyses. A total of 3,023 women used NSAIDs in gestational weeks 0–12 and 64,074 women did not report NSAID use in early pregnancy. No associations were observed between overall exposure to NSAIDs during pregnancy and the selected birth defects separately or as a group (adjusted odds ratio 0.7, 95% confidence interval 0.4–1.1). Associations between maternal use of specific types of NSAIDs and the selected birth defects were not found either, although an increased risk was seen for septal defects and exposure to multiple NSAIDs based on small numbers (2 exposed cases; crude odds ratio 3.9, 95% confidence interval 0.9–15.7). Conclusions Exposure to NSAIDs during the first 12 weeks of gestation does not seem to be associated with an increased risk of the selected birth defects. However, due to the small numbers of NSAID-exposed infants for the individual birth defect categories, increases in the risks of specific birth defects could not be excluded.

Abstract
No information is currently available on the safety of methylephedrine, a component of various cold medications available in South Korea. With previous approval by an Institutional Review Board, 349 women inadvertently exposed to methylephedrine during the 1st trimester of pregnancy and an age- and gravidity-matched control group, were enrolled in a prospective cohort study. Study outcomes, for example gestational age at birth, birth weight and major and minor malformations were evaluated in 282 cases and 280 controls. Exposure to methylephedrine was at a gestational age of 4.0 weeks (median), at doses ranging from 52.5 to 1,575 mg/day, for a median duration of 3 (range: 1-30) days. No differences were observed between cases and controls in any of the pregnancy outcomes studied. There were 4/265 (1.5%) babies born with major malformations in the case group and 4/260 (1.5%) in the control group. In conclusion, inadvertent exposure to methylephedrine as a component of over-the counter oral cold remedies in early pregnancy was not associated with an increased rate of adverse pregnancy outcomes. Co-exposure with acetaminophen, cigarette smoking or alcohol did not appear to modify the outcomes.

Abstract
Substance abuse in pregnancy has increased over the past three decades in the United States, resulting in approximately 225,000 infants yearly with prenatal exposure to illicit substances. Routine screening and the education of women of child bearing age remain the most important ways to reduce addiction in pregnancy. Legal and illegal substances and their effect on pregnancy discussed in this review include opiates, cocaine, alcohol, tobacco, marijuana, and amphetamines. Most literature regarding opiate abuse is derived from clinical experience with heroin and methadone. Poor obstetric outcomes can be up to six times higher in patients abusing opiates. Neonatal care must be specialized to treat symptoms of withdrawal. Cocaine use in pregnancy can lead to spontaneous abortion, preterm births, placental abruption, and congenital anomalies. Neonatal issues include poor feeding, lethargy, and seizures. Mothers using cocaine require specialized prenatal care and the neonate may require extra supportive care. More than 50% of women in their reproductive years use alcohol. Alcohol is a teratogen and its effects can include spontaneous abortion, growth restriction, birth defects, and mental retardation. Fetal alcohol spectrum disorder can have long-term sequelae for the infant. Tobacco use is high among pregnant women, but this can be a time of great motivation to begin cessation efforts. Long-term effects of prenatal tobacco exposure include spontaneous abortion, ectopic pregnancy, placental insufficiency, low birth weight, fetal growth restriction, preterm delivery, childhood respiratory disease, and behavioral issues. Marijuana use can lead to fetal growth restriction, as well as withdrawal symptoms in the neonate. Lastly, amphetamines can lead to congenital anomalies and other poor obstetric outcomes. Once recognized, a multidisciplinary approach can lead to improved maternal and neonatal outcomes.

Abstract
INTRODUCTION Many pregnant women are asthmatics and maternal asthma is a source of questions and complications concerning both the progress of the pregnancy itself and the impact on the foetus. In this situation good asthma control is essential as the disease can deteriorate with acute exacerbations, possibly precipitated by reduction or even withdrawal of treatment on account of fear of teratogenicity. BACKGROUND Even though asthma treatments are not totally harmless during pregnancy, their use has been validated by several studies and guidelines. To help clinicians, we undertake here a review of the complications induced by maternal asthma and its medications, and then suggest management guidelines according to the most recent publications. CONCLUSIONS The risks and benefits of asthma treatments should be explained in a real partnership between the patient and her general practitioner and specialists (obstetrician, chest physician or allergist). In order to reduce complications to both mother and child, perfect control of asthma is required and inhaled steroids remain the treatment of choice for partially or uncontrolled asthma in the pregnant woman.

Abstract
Pseudoephedrine is contained in decongestants such as the Sudafed line of products. It is an alpha-adrenergic receptor agonist, which causes blood vessel constriction, including the therapeutic effect of reducing airflow resistance in the nasal cavity. Pseudoephedrine is one of the most commonly used medications in pregnancy, with an estimated 25% of women exposed. It has been demonstrated that alpha-adrenergic receptor agonists slow uterine blood flow, but their effects have not been studied in relation to most reproductive outcomes in animals or humans. Two analyses of health maintenance organization pharmacy data identified 9 malformed infants among 902 first-trimester pseudoephedrine exposures, suggesting no association with birth defects overall; however, studies of such data sets often lack sufficient power to identify risks for specific birth defects. The related compounds, epinephrine, ephedrine, and phenylephrine, have been associated with hemorrhages and cardiovascular and limb malformations in animal models. Risk of ventricular septal defects was associated with decongestant use in pregnant women in 1 recent study. The vasoconstrictive effects of these drugs raise the hypothesis that their use in early pregnancy might increase the risk of vascular disruption defects. Case-control studies, which often do have power to identify risks related to specific birth defects, have explored this hypothesis. Decongestant use in the first trimester has been associated with small increases in risks of 3 defects thought to arise, at least in some instances, from vascular disruption-gastroschisis, small intestinal atresia, and hemifacial microsomia. These findings are somewhat consistent in terms of magnitude of effect and suggest that risks are even greater among women also exposed to the vasoconstrictive effects of cigarette smoking. There are, however, limitations to these studies, including the possibilities of inaccurate recall of exposures and confounding by indication. In addition, the majority of decongestant use is in oral form and the question of whether intranasal formulations carry risk has not been adequately addressed.

Abstract
Numerous pregnant women suffer from allergic rhinitis, and particular attention is required when prescribing drugs to these patients. In addition, physiologic changes associated with pregnancy could affect the upper airways. Evidence-based guidelines on the management of allergic rhinitis have been published. Medication can be prescribed during pregnancy when the apparent benefit of the drug is greater than the apparent risk. Usually, there is at least one "safe" drug from each major class used to control symptoms. All glucocorticosteroids are teratogenic in animals but, when the indication is clear (for diseases possibly associated, such as severe asthma exacerbation), the benefit of the drug is far greater than the risk. Inhaled glucocorticosteroids (eg, beclomethasone or budesonide) have not been incriminated as teratogens in humans and are used by pregnant women who have asthma. A few H1-antihistamines can safely be used as well. Most oral decongestants (except pseudoephedrine) are teratogenic in animals. There are no such data available for intranasal decongestants. Finally, pregnancy is not considered to be a contraindication for the continuation of immunotherapy.

Abstract
BACKGROUND Many women take non-steroidal anti-inflammatory drugs (NSAIDs) during pregnancy but the risks for the infant remain controversial. We carried out a study to quantify the association between those women prescribed NSAIDs in early pregnancy and congenital anomalies. METHODS A population-based pregnancy registry was built by linking data from three administrative databases in Quebec between 1997-2003. The inclusion criteria were mothers of live singleton infants, between 15-45 years of age, covered by the RAMQ drug plan > or =12 months before and during pregnancy, and prescribed an NSAID or other medications during pregnancy. We selected as cases infants with any congenital anomaly (ICD-9; 740-759) diagnosed in the first year of life. Up to 10 controls, defined as infants with no congenital anomalies detected were selected for each case. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated. RESULTS Within the registry, 36,387 pregnant women met the inclusion criteria. We identified 93 births with congenital anomalies in 1056 women (8.8%) who filled prescriptions for NSAIDs in the first trimester of pregnancy, compared to 2478 in 35,331 (7%) women who did not. The adjusted OR for any congenital anomalies for women who filled a prescription for NSAIDs in the first trimester was 2.21 (95% CI = 1.72-2.85). The adjusted OR for the anomalies related to cardiac septal closure was 3.34 (95% CI = 1.87-5.98). There were no significant associations with anomalies of other major organ systems. CONCLUSIONS Our study suggests that women prescribed NSAIDs during early pregnancy may be at a greater risk of having children with congenital anomalies, specifically cardiac septal defects.
