Psychiatric Medication Use in Pregnancy and Breastfeeding

Effect of aripiprazole on neural tube development in early chick embryos

INTRODUCTION

Aripiprazole (ARI) is a recently developed antipsychotic medication that belongs to the second generation of antipsychotics. The literature has contradictory information regarding ARI, which has been classified as pregnant use category C by the FDA.

METHODS

125 pathogen-free fertilized eggs were incubated for 28 h and divided into five groups of 25 eggs each (including the control group), and 18 eggs with intact integrity were selected from each group. After the experimental groups were divided, ARI was administered subblastodermally with a Hamilton micro-injector at 4 different doses (1 mg/kg, 5 mg/kg, 10 mg/kg, 20 mg/kg). At the 48th hour of incubation, all eggs were hatched and embryos were removed from the embryonic membranes. And then morphologic (position of the neural tube (open or closed), crown-rump length, number of somites, embryological development status), histopathologic (apoptosis (caspase 3), cell proliferation (PCNA), in situ recognition of DNA breaks (tunnel)), genetic (BRE gene expression) analyzes were performed.

RESULTS

According to the results of the morphological analysis, when the frequency of neural tube patency was evaluated among the experimental groups, a statistically significant difference was determined between the control group and all groups (p < 0.001). In addition, the mean crown-rump length and somite number of the embryos decreased in a dose-dependent manner compared to the control group. It was determined that mRNA levels of the BRE gene decreased in embryos exposed to ARI compared to the control group (p < 0.001).

CONCLUSION

Morphologically, histopathologically, and genetically, aripiprazole exposure delayed neurogenesis and development in early chick embryos. These findings suggest its use in pregnant women may be teratogenic. We note that these results are preliminary for pregnant women, but they should be expanded and studied with additional and other samples.

Advances in Psychotropic Treatment for Pregnant Women: Efficacy, Adverse Outcomes, and Therapeutic Monitoring

Advancements in psychotropic therapy for pregnant women are pivotal for addressing maternal mental health during the perinatal period. Screening for mood and anxiety symptoms during pregnancy is recommended to enable early intervention. Psychotropic medications, including antidepressants, benzodiazepines, antipsychotics, and mood stabilizers, are commonly used, but challenges remain regarding their safety and efficacy during pregnancy. Pregnancy induces significant changes in pharmacokinetics, necessitating personalized dosing strategies and careful monitoring. Real-time monitoring technologies, such as smartphone-integrated platforms and home-based monitoring, enhance accessibility and accuracy. Prospective studies and collaboration among healthcare providers are essential for evidence-based guidelines and optimal treatment strategies. Reducing stigma around mental health during pregnancy is crucial to ensure women seek help and discuss treatment options, promoting understanding and acceptance within the community.

The role of gut microbiota and blood metabolites in postpartum depression: a Mendelian randomization analysis

Background

Postpartum depression (PPD) is a common complication of pregnancy that imposes a heavy health and economic burden on individuals, families and society. The etiology of PPD is complex and incompletely defined, and recent studies have identified an important role for gut microbiota (GM) and their metabolites in neurological disorders. However, fewer studies on GM and PPD are available and have not yielded uniform results.

Methods

Instrumental variables for GM and blood metabolites were obtained from the MiBioGen consortium and metabolomics GWAS server. Single nucleotide polymorphisms (SNPs) associated with PPD phenotypes were obtained from the FinnGen consortium. Inverse variance weighted (IVW), weighted median, weighted mode, and MR-Egger methods were used to assess causal effects. Inverse MR analysis and sensitivity analysis were also utilized to improve the stability of the results.

Results

In this study, 5 intestinal species and 24 blood metabolites causally associated with PPD were identified using MR analysis. In addition, MR analysis showed that Prevotellaceae and Bifidobacteria may reduce the risk of PPD by elevating Xanthine and 1-arachidonoylglycerophosphoinositol (LysoPI) levels.

Conclusions

This study identified GM and blood metabolites causally associated with PPD. The results of this study may provide a theoretical basis for the discovery of PPD-related biomarkers and the treatment of the disease by regulating the gut microenvironment.

Evaluation of three-year neurodevelopmental outcomes in infants prenatally exposed to substance use

INTRODUCTION

Prenatal exposure to substance use is associated with long-term deficits in the neurodevelopment of children. The objective was to investigate the association between cognitive, motor, and language neurodevelopment at three years of age in infants prenatally exposed to substance use.

MATERIAL AND METHODS

A prospective matched case-control study was conducted. Biomarkers of fetal exposure were measured in meconium samples. The Bayley Scales of Infant and Toddler Development (BSID-III) were used to calculate neurodevelopment scores.

RESULTS

32 non-exposed and 32 exposed infants were evaluated, of which 16 were exposed to cannabis, 8 to ethanol, 2 to cocaine and 6 to more than one substance. Normal BSID-III scores ≥85 in all domains, were detected in 23 exposed infants to any substance and 29 infants non-exposed. Neurodevelopmental delay was detected in the language domain, specifically in male infants exposed to cannabis. Two infants exposed to cannabis had a severe developmental delay (score<70). Infants exposed to any substance obtained significantly lower total scores than control infants in all domains. Infants exposed to cannabis obtained significantly lower composite scores in the cognitive and motor domains. Infants exposed to more than one substance had lower scores in motor skills. By gender, only males exposed obtained significantly lower composite scores than non-exposed males in the cognitive domain.

CONCLUSIONS

The most common and severe neurodevelopmental delay at 36 months was detected in the domain of language in male infants prenatally exposed to cannabis. Neurodevelopmental disorders detected can enable an early intervention and plan therapeutic strategies.

Depression, anxiety, and stress in pregnant Black people: A case for screening and evidence-based intervention

BACKGROUND

Guidelines call for pregnant people to be screened for depression and anxiety. Screening may be particularly important for pregnant Black individuals who are reported to be more likely than non-Hispanic White pregnant people to experience prenatal stress, anxiety, and depressive symptoms. The purpose of this study was to determine if depression, anxiety, and stress co-occur in pregnant Black people and to identify which demographic factors are related to these mental health concerns.

METHODS

A subset analysis of an ongoing randomized controlled trial examined the risk of coexisting mental health conditions in pregnant Black people who screened eligible to participate (that is, they had high levels of depression, anxiety, and/or stress) in two urban clinics using a descriptive correlational design.

RESULTS

Of the 452 pregnant Black people who were screened for eligibility, 194 (42.9%) had elevated scores on depression, anxiety, and/or stress measures and were enrolled in the larger study. The average scores of the 194 enrolled participants were anxiety, mean (M) = 9.16 (standard deviation [SD] = 4.30); depression, M = 12.80 (SD = 4.27); and stress, M = 21.79 (SD = 4.76). More than one-third (n = 70, 36.1%) experienced two symptoms and 64 (33.0%) reported all three symptoms.

CONCLUSION

Pregnant Black individuals experience high levels of comorbid mental health distress including depression, anxiety, and stress. The findings indicate that treatment for mental health concerns needs to be broad-based and effective for all three conditions. Prenatal interventions should aim to address mental health distress through screening and treatment of depression, anxiety, and stress, especially for pregnant Black individuals. This study furthers understanding of the prevalence of prenatal mental health conditions in pregnant Black people.

Development and acceptability of a decision aid for major depressive disorder considering discontinuation of antidepressant treatment after remission

Aim

While evidence‐based antidepressant treatment is available for major depressive disorder, standard approaches for discontinuation of antidepressants after remission have not yet been established. Decision aids are structured clinical tools that facilitate shared decision‐making between patients and healthcare providers. This study aimed to describe the development process and acceptability of decision aids for major depressive disorder following discontinuation of antidepressant treatment after remission.

Methods

We systematically developed a decision aids according to the International Patient Decision Aid Standards. First, a decision aids prototype was created using the results of a systematic review and meta‐analysis previously conducted to identify the consequences of continuing and discontinuing antidepressant treatment. Second, a mixed‐methods questionnaire (alpha acceptability testing) was administered to patients and healthcare providers to improve the decision aids prototype and develop it into a final version acceptable for clinical settings.

Results

Our decision aids consisted of a description of major depressive disorder, the option to continue or discontinue antidepressant treatment, the advantages and disadvantages of each option, the consequences of each option, and value clarification exercises for each option. The patients (n = 22) reported that the decision aids had acceptable language (91%), adequate information (91%), and a well‐balanced presentation (95%). Healthcare providers (n = 20) provided favorable feedback. The final decision aids fulfilled all six International Patient Decision Aid Standards qualifying criteria.

Conclusion

We successfully developed a decision aids for discontinuation of antidepressant treatment after remission, which could be used during the shared decision‐making process. Further studies are needed to verify the effects of using the decision aids during the shared decision‐making process.
