Chapter 52 covers the topic of pregnancy and breastfeeding. Through a case vignette with topical MCQs for consolidation of learning, readers are brought through the management of pregnant patients with psychiatric disorders from first presentation to subsequent complications of the conditions and its treatment. Things covered include the general principles of prescribing in patients with pregnancy or who are breastfeeding, the use of antidepressants, the use of mood stabilisers, the use of antipsychotics.
Physiologic changes in the peripartum period put women with CHD at increased risk for morbidity. This study examines factors associated with peripartum complications and length of stay compared to patients without CHD.
Methods:
This single-institution retrospective case-control study included women with CHD (2000–2017) and a control population without CHD. A review of clinical and echocardiographic data was used to assign baseline characteristics, disease severity, and adverse outcomes. Primary outcomes were composite variables of cardiac and obstetric adverse events, along with peripartum length of stay. The relationship between maternal CHD, baseline characteristics, and peripartum adverse events was evaluated by multivariable regression.
Results:
The cohort and control groups included 162 deliveries among 113 women and 321 deliveries among 321 women, respectively. Cardiac complications, including arrhythmia, heart failure, pulmonary oedema, and thromboembolic events, occurred in 8.6% of the cohort (RR 2.52, 95% CI 1.17–5.42), with the most common event being arrhythmia. Obstetric events, such as caesarean delivery, assisted vaginal delivery, preterm birth, and pre-eclampsia, occurred in 67.9% versus 56.1% in the control group (RR 1.21, 95% CI 1.05–1.40). In multivariable models, increasing age was associated with increased composite cardiac events. Length of stay was longer in the cohort group (p < 0.001) and significantly associated with modified World Health Organization classification (p = 0.016).
Conclusions:
Women with CHD experience increased cardiac and obstetric morbidity compared to controls during peripartum admission. Those with CHD have longer hospital stays around delivery, which is associated with disease severity.
Endothelial progenitor cells (EPCs) are key regulators of vascular homeostasis in both health and disease, playing a crucial role in regenerating the human vascular lining throughout life. These circulating cells can differentiate into mature endothelial cells and are increasingly recognized as important biological markers of vascular function and cumulative risk for various diseases, including cardiovascular conditions. In recent decades, the role of EPCs, particularly the endothelial colony-forming cells (ECFCs) subtype, in pregnancy-related disorders and maternal and neonatal endothelial health has garnered significant attention. Evidence suggests that ECFCs may serve as predictor of future endothelial health in women and their offspring following pregnancy complications, making them particular relevant for research and therapeutic applications in adulthood, as well as potential indicators of vascular health. This review summarizes the evidence on EPCs, specifically ECFCs, as biomarkers of endothelial health in pregnancy, pregnancy-related diseases and ageing, with a focus on maternal and foetal endothelial abnormalities that may serve as prognostic factors for the development of future diseases.
Certain prescription drugs used during pregnancy are associated with offspring autism spectrum disorder (ASD). Nonetheless, ASD risk following prenatal exposure to most drugs remains unknown. Furthermore, methodological challenges and ethical concerns hinder the scope for causal inference.
Methods
We used a case-cohort study design of a nationally representative sample from Israel to examine the associations between maternal prescription drug use during pregnancy and offspring ASD. To scrutinize these associations, the analyses were (a) adjusted for indication proxy (level 2 Anatomical Therapeutic Chemical (ATC) codes), (b) repeated using shared pharmacological targets as exposures, and (c) inspected further through target-enrichment analysis.
Results
The sample included 1,400 individuals with and 94,713 without an ASD diagnosis. Among all drugs prescribed during pregnancy, five were statistically significantly associated with increased offspring ASD risk after adjustment for indication proxy (e.g., hazard ratio [95% confidence interval] cyproterone = 2.71 [1.17–6.25] and prednisolone = 2.10 [1.27–3.49]), and two with decreased risk (ferrous sulfate = 0.82 [0.68, 0.99] and lynestrenol = 0.43 [0.2, 0.93]). Further analysis revealed four pharmacological targets shared by these drugs, which were themselves associated with ASD (e.g., neuronal acetylcholine receptor α4β4 = 1.45 [1.05–1.99] and serotonin 2b receptor = 1.31 [1.04–1.61]). Enrichment analysis suggested the association between ASD and medications affecting cholinergic and serotonergic signaling.
Conclusions
Increased ASD risk followed prenatal exposure to five prescription drugs, and decreased risk followed exposure to two. Subsequent analyses suggested no confounding by indication in these associations, but further studies are warranted.
Fear of childbirth (FoB) is a common experience during pregnancy which can cause clinically significant distress and impairment. To date, a number of investigations of FoB have assumed that clinically significant FoB is best understood as a type of specific phobia. However, preliminary evidence suggests that specific phobia may not be the only diagnostic category under which clinically significant symptoms of FoB are best described.
Aim:
The current study is the first to investigate which DSM-5 diagnostic categories best describe clinically significant symptoms of FoB.
Method:
Pregnant people reporting high levels of FoB (n=18) were administered diagnostic interviews related to their experience of FoB.
Results:
Participants (n=18) were predominantly nulliparous (73.3%), cisgender women (83.3%). Of these, 14 (77.8%) met criteria for one or more DSM-5 anxiety-related disorders. Preliminary findings suggest that primary FoB may align with specific phobia criteria, whereas secondary FoB (following a traumatic birth) may be better classified under post-traumatic stress disorder (PTSD). FoB also featured in other anxiety-related disorders but was not the primary focus (e.g. obsessive-compulsive disorder). Four participants did not meet criteria for any DSM-5 disorder.
Conclusions:
Findings provide preliminary evidence that clinically significant FoB fits within existing DSM-5 categories, in particular specific phobia and PTSD. Although FoB-related concerns appears in other anxiety-related disorder categories, it does not appear as the primary focus. Although informative, due to the small sample employed in this research, replication in larger and more diverse samples is needed.
To describe the nutritional intake and status of pregnant women in Bloemfontein and compare across different household food security categories.
Design:
Cross-sectional.
Setting:
Pelonomi Tertiary Hospital.
Participants:
427 pregnant women were interviewed using a standard questionnaire and a quantitative FFQ to collect socio-demographic, HIV status, household food security, supplement and dietary intake data. Weight and height were measured using standard anthropometric techniques and capillary blood taken by finger-prick for anaemia, Fe and inflammation status assessment.
Results:
26·7 % of participants were food secure, while 11·5 %, 32·1 % and 29·5 % experienced mild, moderate and severe food insecurity, respectively. 54·5 %, 41·7 % and 31·1 % were obese, anaemic and Fe deficient. Median energy intake was 8808 (6978–9223) KJ/d, with no significant differences between the food security groups (P = 0·517). Based on the dietary reference intakes, 98·1 % met the estimated average requirement (EAR) for carbohydrates, but the majority had sub-optimal intake of protein (58·3 %), fibre (60·9 %), pantothenic acid (67·0 %), vitamins C (65·6 %), D (68·4 %), E (59·0 %) and K (61·8 %), potassium (99·8 %), dietary Ca (95·8 %) and Fe (80·8 %). Compared with the moderately and severely food-insecure counterparts, food-secure participants had a higher intake of animal protein (P < 0·001), total fat (P = 0·014), monounsaturated fat (P = 0·002), vitamins B12 (P = 0·014), C (P < 0·001) and D (P = 0·003) and dietary Ca (P = 0·001). Dietary folate intake was below the EAR in 69·9 %, but was higher among severely food-insecure participants (463·94 (327·39, 609·71) µg than food secure (378·49 (265·99, 496·15) µg, P = 0·007)).
Conclusion:
The findings show widespread inadequate nutrient intake among pregnant women in Bloemfontein, with food-insecure women showing significantly lower intake of specific nutrients.
Recently, the role of abortion access in the workplace and the field of I-O psychology has been highlighted, but little published research explicitly tackles the impacts of abortion care from an organizational psychology perspective. We examine the potential impacts of further restrictions on abortion access within the context of people’s relationships with employment and workplaces. We focus our discussion on three significant mechanisms that may further restrict access to abortion depending on the degree to which they are enforced or enacted: restriction of abortion medication and equipment shipping, limiting federal funding for organizations that facilitate abortion access, and fetal personhood laws. Further restriction of abortion access may create significant challenges for organizational decision makers, employees, and healthcare workers. Together, these changes to the experience of work necessitate shifts in research and practice within the field of I-O psychology. I-O researchers and practitioners must work together to facilitate organizational functioning and employee well-being through these changes by becoming and staying informed about organizational benefit policies and reproductive care-related practices and their impact on employees, employee career trajectories and distress related to unwanted pregnancy, and moral injury and other challenges faced by healthcare workers.
An adverse in utero experience negatively impacts perinatal growth in livestock. Maternal heat stress (HS) during gestation reduces placental growth and function. This progressive placental insufficiency ultimately leads to fetal growth restriction (FGR). Studies in chronically catheterized fetal sheep have shown that FGR fetuses exhibit hypoxemia, hypoglycemia, and lower anabolic hormone concentrations. Under hypoxic stress and nutrient deficiency, fetuses prioritize basal metabolic requirements over tissue accretion to support survival. Skeletal muscle is particularly vulnerable to HS-induced placental insufficiency due to its high energy demands and large contribution to total body mass. In FGR fetuses, skeletal muscle growth is reduced, evidenced by smaller myofiber size and mass, reduced satellite cell proliferation, and slower rate of protein synthesis. Disruptions in skeletal muscle growth are associated with mitochondrial dysfunction, including reduced pyruvate flux into the mitochondrial matrix and lower complex I activity in the mitochondrial electron transport chain. This review summarizes current research on the mechanisms by which HS-induced placental insufficiency affects skeletal muscle growth in the fetus, with an emphasis on myogenesis, hypertrophy, protein synthesis, and energy metabolism. The evidence presented is primarily drawn from experiments using chronically catheterized fetal sheep exposed to maternal HS during mid-gestation. Additionally, we explore emerging nutritional strategies aimed at enhancing skeletal muscle growth in animals with FGR. These strategies hold promise not only for improving reproductive efficiency in livestock affected by prenatal stress but also for their translational relevance to human pregnancies complicated by placental insufficiency.
Postpartum depression is prevalent among Black women and associated with intersecting systemic factors and interpersonal discrimination. However, gaps remain in understanding pregnancy-related changes in discrimination experiences that influence postpartum mental health and could inform preventive interventions. We hypothesized that young Black women would experience increasing levels of discrimination across the transition to parenthood, heightening depression risk relative to non-pregnant peers.
Methods
Participants comprised 335 Black primiparous women (ages 17-30 at delivery) and 335 age- and discriminationmatched non-pregnant controls from the Pittsburgh Girls Study. Self-reported discrimination experiences were collected at four timepoints: two years pre-pregnancy, one year pre-pregnancy, pregnancy, and one year postpartum for the childbearing sample, with corresponding data from the non-pregnant sample across the same interval (matched pairwise).
Results
Linear increases in discrimination were observed for the nonpregnant participants (BS = .480, SE = .090, p <.001), while childbearing participants showed no overall changes, though younger age predicted greater increases over time. For childbearing participants, both baseline discrimination (BI = .626, SE = .077, p < .001) and increasing discrimination (BS = 2.55, SE = .939, p < .01) predicted postpartum depressive symptoms, controlling for pre-pregnancy depression. Among non-pregnant participants, only baseline discrimination predicted later depression (BI = .912, SE = .081, p < .001).
Conclusions
Experiencing increasing levels of interpersonal discrimination across the transition to parenthood may heighten postpartum depression risk among young Black women, indicating a need for interventions supporting well-being and promoting resilience before, during and after pregnancy.
Using a behavioural intervention to target nutrition during pregnancy may be key in meeting recommendations for healthy eating. The aim was to assess the use of a short-term dietary intake measurement tool (3-day food intake record) to infer long-term habitual dietary intake during pregnancy (using a short-form FFQ). A convenience sample (n 90) between 12- and 18-weeks’ gestation was recruited from a larger randomised controlled trial for cross-sectional analysis. Participants completed a forty-four-item FFQ and 3-day food intake record. Using the participant food intake record, the investigator blindly completed a second frequency questionnaire. The frequency questionnaires were scored using dietary quality scores (DQS) and compared. Aggregate data were evaluated using a Wilcoxon signed rank test, and individual-level data were evaluated using a Bland–Altman plot. No significant difference was observed in the scores (Z = –1·88, P = 0·06), with small effect size (r= 0·19). The Bland–Altman plot showed that comparing the DQS derived from the two different dietary assessments underestimated scores by a mean difference of 0·4 points (95 % limits of agreement: −3·50 to 4·26). The data points were evenly spread suggesting no systematic variation for over- or underestimation of scores. Minimal difference was observed between the functionality of the two assessment instruments. However, the food intake record can be completed by pregnant individuals to estimate short-term nutrient intake and then scored by the investigator to estimate long-term dietary quality. Combining these two instruments may best capture the most accurate representation of dietary habits over time.
Acute infection with Toxoplasma gondii in pregnant people can lead to vertical transmission to the foetus and congenital toxoplasmosis. As part of risk assessment, the epidemiology of toxoplasmosis among pregnant people must be quantitatively elucidated. Herein, we investigated the risk of primary T. gondii infection during pregnancy in Japan, estimating the incidence of T. gondii infection among pregnant people as well as that of congenital toxoplasmosis. We used a compartment model that captured the infection dynamics in pregnant people, analysing prescription data for spiramycin in Japan, together with local serological testing results and the screening rate of primary T. gondii infection during pregnancy. The nationwide risk of T. gondii infection pregnant people in Japan was estimated to be 0.016% per month. Among prefectures investigated, the risk estimate was highest in Tokyo with 0.030% per month. Nationally, the number of T. gondii infections among pregnant people in the years 2019, 2020, and 2021 was estimated to be 1507, 1440, and 1388 infections, respectively. The nationwide number of cases of congenital toxoplasmosis in each year was estimated at 613, 588, and 567 cases, respectively. Our study indicated that T. gondii infection continues to place a substantial burden on public health in Japan.

Content on the physiology of pregnancy focuses on the commonly examined areas including the cardiovascular, respiratory, endocrine and haematological changes in pregnancy, then the subsequent impact upon conduct of anaesthesia. We include a section on the materno-fetal circulation and the placenta, with an emphasis on the changes that occur at birth.
Lamotrigine is beneficial in bipolar disorder and is often prescribed to patients during their period of reproductive potential. We summarise aspects of the pharmacology of lamotrigine, highlight its uses in psychiatric practice, drawing attention to recent findings relating to potential hazards arising from lamotrigine exposure in utero, and make some suggestions for clinical management.
During pregnancy, colonization by genital mycoplasmas may be associated with adverse outcomes. This study was conducted to investigate the prevalence of four species of Mollicutes (Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma parvum, and Ureaplasma urealyticum) in pregnant women receiving high-risk prenatal care and to evaluate possible associated factors. Data collection included the application of a questionnaire and the collection of cervical swabs from pregnant women. Species identification was performed by real-time PCR. The overall prevalence of Mollicutes was 60.97%. 55.9% of pregnant women were colonized by Ureaplasma spp., and 19.51% by Mycoplasma spp. The prevalence rates by species were 48.78% for U. parvum, 11.59% for U. urealyticum, 18.9% for M. hominis, and 1.22% for M. genitalium. Age, 12 years of schooling or more, age at first sexual intercourse up to 14 years, third trimester of pregnancy, having undergone infertility treatment, presence of STI, and groin lymph nodes were associated with a higher prevalence of microorganisms. The results presented are of utmost importance for understanding the prevalence of these microorganisms, the characteristics of colonized pregnant women, and planning screening strategies and interventions that minimize the negative impacts of these infections.
About 13% of pregnant women with substance use disorder (SUD) receive treatment and many may encounter challenges in accessing perinatal care, making it critical for this population to receive uninterrupted care during a global pandemic.
Methods
From October 2021-January 2022, we conducted an online survey of pregnant and postpartum women and interviews with clinicians who provide care to this population. The survey was administered to pregnant and postpartum women who used substances or received SUD treatment during the COVID-19 pandemic.
Results
Two hundred and ten respondents completed the survey. All respondents experienced pandemic-related barriers to routine health care services, including delays in prenatal care and SUD treatment. Disruptions in treatment were due to patient factors (38.2% canceled an appointment) and clinic factors (25.5% had a clinic cancel their appointment). Respondents were generally satisfied with telehealth (M = 3.97, SD = 0.82), though half preferred a combination of in-person and telehealth visits. Clinicians reported telehealth improved health care access for patients, however barriers were still observed.
Conclusions
Although strategies were employed to mitigate barriers in care during COVID-19, pregnant and postpartum women who used substances still experienced barriers in receiving consistent care. Telehealth may be a useful adjunct to enhance care access for pregnant and postpartum women during public health crises.
Tania starts her story with the dramatic description of her being prepared for ECT while pregnant. She has made an advance decision to have this treatment if she gets unwell during the pregnancy or after giving birth. Such a decision is also known as a Ulysses Pact. She wanted to get pregnant and knew that there was a strong risk of relapse of her bipolar disorder, which would make the pregnancy very risky. The story continues with the description of her life which was affected by episodes of illness that responded to ECT, and subsequent relapses. Over the last few years Tania has been on maintenance ECT and has had more than 200 sessions altogether. This did not prevent her from progressing into a very successful academic career. At one point she was at the Institute of Psychiatry in London, jointly leading a large research project on mental health advance directives, making her uniquely qualified to write on this topic.
Several dietary strategies are designed to achieve optimal glycaemic control in managing gestational diabetes mellitus (GDM), considering factors such as energy needs, the glycaemic index, high fibre content and the reduction or exclusion of sugary foods and drinks. However, in achieving therapeutic goals, there is a lack of consensus in the formulation of uniform recommendations. This article reviews the literature to assess the impact of dietary interventions on GDM risk – measured by the percentage of at-risk women who develop GDM – and on the progression of GDM pregnancies, including weight gain, hyperglycaemia severity, insulin requirements and perinatal outcomes such as macrosomia, hypertensive disorders, caesarean delivery and neonatal size. We conducted a thorough search of PubMed and the Cochrane Library, focusing on randomised controlled trials, cohort studies, systematic reviews and meta-analyses involving women either at risk of or diagnosed with GDM. These search criteria yielded 2800 articles, whose titles and abstracts were reviewed to determine their relevance to the research objective. In the initial search, 192 relevant articles met the inclusion criteria. The comprehensive analysis of these studies highlights the current uncertainty regarding the long-term consequences of recommended diets during pregnancy, especially among women with GDM. While the available literature is substantial, conclusions drawn from various methodologies and study populations have not yielded a consensus on the most effective diet for reducing perinatal complications. Nonetheless, it is reasonable to advocate for the early initiation of dietary interventions, particularly during pregnancy planning, especially among women exhibiting risk factors for GDM.
The purpose of this study was to report on the prevalence of hypertension and anaemia, and types of medications prescribed to expectant mothers attending antenatal clinics at Intermediate Hospital Katutura in Windhoek, Namibia.
Background:
Millennium Development Goals 4 and 5 speak to reduction of child mortality and improvement of maternal health by 2015, respectively. Gestational hypertension is a major contributor to maternal and perinatal mortality and is reported to affect up to 10% of women world-wide. Prevalence of anaemia among pregnant women is reported higher in low- and middle-income countries than in developed countries.
Methods:
This was a cross-sectional study involving the review of outpatient and clinic health records for patients attending antenatal clinics at Intermediate Hospital Katutura, Windhoek during October to November 2022. Data for patients on first antenatal clinic visit were obtained from facility antenatal clinic patient registers while that of follow-up patients were from patient health passports. All expectant mothers over 18 years of age who had provided written consent to participate, were included. Data collected were: age, body weight, haemoglobin concentration, blood pressure, gravida, number of babies delivered, pregnancy stage, comorbidities, and prescribed medications. The results were summarised using descriptive statistics. A p-value <0.05 is considered to be statistically significant.
Findings:
354 records were included: 303 (85.6%) first visit, and 51 follow-up (14.4%). There was a significant correlation between systolic blood pressure (BP) and body weight (r = 0.31, p < 0.001). 13.5% of first-time visitors had haemoglobin levels lower than the normal range (11 g/dL). Difference in haemoglobin levels between trimesters 1 and 3 were significant (p < 0.001). Methyldopa was prescribed for all hypertensive expectant mothers. To reduce the incidences of anaemia and hypertension during pregnancy, women of childbearing age should be encouraged to attend antenatal visits earlier in pregnancy and to take measures for body weight reduction, respectively.
