Teratogen update: Amphetamines.

Amphetamines are synthetic noncatecholamine sympathomimetic amines that act as psychostimulants. They have been prescribed for the treatment of attention-deficit/hyperactivity disorder (ADHD), narcolepsy, and additional health conditions. Amphetamines are also drugs of abuse. Some experimental animal studies suggested adverse developmental effects of amphetamines, including structural malformations. These effects were most often observed in experimental animals at higher dose levels than those used for treatment or abuse and at dose levels that produce maternal toxicity. Controlled studies of amphetamine use for the treatment of ADHD and other indications did not suggest that amphetamines are likely to cause structural malformations, although there are three studies associating medication for ADHD or methamphetamine abuse with gastroschisis. We did not locate studies on the neurobehavioral effects of prenatal exposures to therapeutic amphetamine use. Amphetamine abuse was associated with offspring neurobehavioral abnormalities, but lack of adequate adjustment for confounding interferes with interpretation of the associations. Adverse effects of methamphetamine abuse during pregnancy may be due to factors associated with drug abuse rather than methamphetamine itself. The adverse effects observed in methamphetamine abuse studies may not be extrapolatable to amphetamine medication use.

Association of Autism Spectrum Disorder With Prenatal Exposure to Medication Affecting Neurotransmitter Systems.

Importance: Prenatal exposure to certain medications has been hypothesized to influence the risk of autism spectrum disorders (ASD). However, the underlying effects on the neurotransmitter systems have not been comprehensively assessed. Objective: To investigate the association of early-life interference with different neurotransmitter systems by prenatal medication exposure on the risk of ASD in offspring. Design, Setting, and Participants: This case-control study included children born from January 1, 1997, through December 31, 2007, and followed up for ASD until January 26, 2015, within a single Israeli health maintenance organization. Using publicly available data, 55 groups of medications affecting neurotransmitter systems and prescribed to pregnant women in this sample were identified. Children prenatally exposed to medications were compared with nonexposed children. Data were analyzed from March 1, 2017, through June 20, 2018. Main Outcome and Measures: Hazard ratios (HRs) and 95% CIs of ASD risk associated with exposure to medication groups using Cox proportional hazards regression, adjusted for the relevant confounders (eg, birth year, maternal age, maternal history of psychiatric and neurologic disorders, or maternal number of all medical diagnoses 1 year before pregnancy). Results: The analytic sample consisted of 96 249 individuals (1405 cases; 94 844 controls; mean [SD] age at the end of follow-up, 11.6 [3.1] years; 48.8% female), including 1405 with ASD and 94 844 controls. Of 34 groups of medications, 5 showed nominally statistically significant association with ASD in fully adjusted models. Evidence of confounding effects of the number of maternal diagnoses on the association between offspring exposure to medication and ASD was found. Adjusting for this factor, lower estimates of ASD risk among children exposed to cannabinoid receptor agonists (HR, 0.72; 95% CI, 0.55-0.95; P = .02), muscarinic receptor 2 agonists (HR, 0.49; 95% CI, 0.24-0.98; P = .04), opioid receptor κ and ε agonists (HR, 0.67; 95% CI, 0.45-0.99; P = .045), or α2C-adrenergic receptor agonists (HR, 0.43; 95% CI, 0.19-0.96; P = .04) were observed. Exposure to antagonists of neuronal nicotinic acetylcholine receptor α was associated with higher estimates of ASD risk (HR, 12.94; 95% CI, 1.35-124.25; P = .03). Conclusions and Relevance: Most of the medications affecting neurotransmitter systems in this sample had no association with the estimates of ASD risk. Replication and/or validation using experimental techniques are required.

Pharmacotherapy for Perinatal Depression.

Perinatal depression is associated with serious risks for the mother, baby, and family. When considering treating perinatal depression with a drug indicated for the treatment of depression, the major concerns are whether the drug increases the risks of teratogenicity, pregnancy complications, poor neonatal adaptation, or neurodevelopmental disorders. Although different studies have produced different results, the majority have not shown increases in risk for selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, tricyclic antidepressants, or the noradrenergic/dopaminergic drug bupropion. In this review we will discuss the reproductive safety data for these medications as well as monoamine oxidase inhibitors and benzodiazepines.

Bipolar Disorder in Pregnancy and Postpartum: Principles of Management.

Pregnancy and postpartum represent times of increased vulnerability for women with bipolar disorder, yet this condition remains under-diagnosed and under-treated. As 50 % of pregnancies are unplanned, the risks associated with the illness and the potential risks associated with treatment should be considered when a woman of reproductive age first presents for evaluation. This article reviews the epidemiology of perinatal bipolar disorder, screening recommendations, and treatment with pharmacotherapy and electroconvulsive therapy (ECT). An overview of the data in pregnancy and lactation is presented for lithium, lamotrigine, valproic acid, newer antipsychotics, and ECT. General principles of management include close monitoring in pregnancy and postpartum, careful adjustment of the treatment regimen to attenuate the risk of relapse, and avoidance of valproic acid when possible. Thoughtful consideration of these issues will minimize the risks to the mother and baby.

Journal club for faculty or residents: a model for lifelong learning and maintenance of certification.

The journal club offers a model for lifelong learning and maintenance of certification (MOC) for residents and faculty staff. First, it sharpens participants' critical appraisal skills by providing a space to discuss relevant medical literature. Second, it motivates participants to seek new medical literature on their own using technology. Our model sets forth a four-year journal club curriculum that could be used as one continuous curriculum or in bits and pieces. In the first year, the focus is teaching residents how to read an article. The second year focuses on what is of interests to the reader. The third year applies the resident's appraisal skills to assigned articles to test whether they can determine which have reliable and valid findings and which are flawed. In the fourth year residents are asked to distinguish whether articles are well researched and referenced. Our model also motivates participants to read articles in faculty journal clubs throughout their career. In most academic settings category 1 continuing medical education (CME) credits can be awarded so journal club can have the added benefit of satisfying maintenance of certification CME credits. From journal club both residents and faculty can learn what is new and learn to apply this new information in their practice. Finally, because technology creates an overabundance of relevant medical literature, participants using our model can develop strong critical appraisal skills and methods for organizing the information they find that make this information readily available for future use and retrieval.

Perinatal depression: hiding in plain sight.

OBJECTIVE: To promote prompt identification and treatment ofperinatal depression and enhance preventive care for women at risk. METHODS: Using MEDLINE and PubMed searches, we reviewed the recent research on the origins, course, and consequences of pregnancy-related depression. RESULTS: Depressive disorders are more common in pregnancy and postpartum than widely assumed, and there is no predictable protective effect of pregnancy. Relapse rates are high, and the postpartum period represents a time of increased vulnerability to depression. CONCLUSION: Early identification and treatment ofperinatal depression will minimize morbidity and mortality for the woman, the child, and the family.
