Network analysis of spousal support and fear of childbirth in pregnant women of advanced maternal age

BackgroundFear of childbirth is an important perinatal mental health concern, particularly among women of advanced maternal age. However, the specific interrelations between spousal support and fear of childbirth remain unclear.MethodsThis cross-sectional study recruited 279 pregnant women of advanced maternal age from a tertiary hospital in Henan, China, using convenience sampling. Spousal support and fear of childbirth were assessed using the Spouse Support Inventory and the Childbirth Attitude Questionnaire. A regularized partial-correlation network was estimated using EBICglasso, and central and bridge nodes were identified. Network stability was examined using bootstrap procedures.ResultsThe prevalence of any fear of childbirth, defined as a CAQ score ≥28 and including mild, moderate, and severe categories, was 86.4% (n = 241). Negative associations predominated between the spousal support and fear of childbirth communities. The strongest cross-community association was observed between “teaching you how to do things you do not know how to do” and “concern about fetal health.” The most central nodes were “participating in activities together to reduce your stress” and “providing you with helpful information,” whereas the strongest bridge nodes were “helping you understand why things did not go well” and “giving you encouragement.ConclusionSpecific supportive behaviors, especially informational and cognitive-appraisal support, occupied central positions in the network linking spousal support and fear of childbirth among pregnant women of advanced maternal age. Strengthening these forms of spousal support may inform the development of couple-based interventions to reduce childbirth fear and promote perinatal mental health.

Psychotherapy initiation is associated with discontinuation of psychotropic medications without dose escalation: a ten-year real-world cohort study (2014-2024)

BackgroundIncreasing psychotropic prescribing has raised concerns about long-term safety and regimen complexity in mental health care. Although psychotherapy is an established treatment, its role in medication optimization and psychotropic medication reduction in real-world practice across patient subgroups remains insufficiently characterized.ObjectiveTo evaluate whether initiation of psychotherapy is associated with short-term changes in psychotropic medication exposure and regimen complexity, and to examine differences by sex, age, and diagnostic category. Methods: A retrospective cohort study was conducted using anonymized pharmacy dispensing data from the Mental Health Service of Hospital Marina Baixa (Alicante, Spain) between 2014 and 2024. Patients with at least one active prescription for a benzodiazepine or antidepressant within 90 days before psychotherapy initiation were included. Psychotropic exposure was compared in symmetric 90-day pre- and post-therapy windows using number of active agents, total Defined Daily Doses, and prevalence of benzodiazepine and antidepressant use, with stratified analyses by sex, age group, and diagnosis.ResultsThe cohort comprised 86,502 patients and 20.76 million dispensations. The median number of psychotropic medications decreased from 5 to 2 (p < 0.001), while total dose remained stable (median Defined Daily Dose ≈ 21.7; p = 0.999). Benzodiazepine use declined from 87.6% to 67.5% and antidepressant use from 81.8% to 68.8% (both p < 0.001). Men were more likely than women to discontinue benzodiazepines (odds ratio 1.27, 95% confidence interval 1.13–1.43), and simplification increased with age (median reduction −1 in <18 years to −4 in ≥65 years). The largest benzodiazepine reductions occurred in depressive, personality, and episodic mood disorders (−23 to −27 percentage points).ConclusionsIn routine public mental health care, psychotherapy initiation is associated with substantial simplification of psychotropic treatment regimens without increasing overall medication dose, supporting a potential role in facilitating rational medication simplification.

Brain-Infiltrating T Cells Linked to Social Deficits in Autism Mouse Model

The prevalence of autism spectrum disorder (ASD) is roughly one in 36 people, with a male-to-female ratio of 4:1. The disorder is known to be influenced by multiple factors, both genetic (gene mutations and copy number variations) and environmental, such as infections during pregnancy. However, the role of immunity in genetic ASD remains unclear.

One area of interest lies in lymphocytes—cells that are known to shape neurodevelopment and behavior. But their roles in neurodevelopmental disorders are not well defined.

Now, new research shows that a subset of T cells—γδ T cells—can infiltrate the brain and contribute to changes in social behavior in a genetic mouse model that mimics behavioral features of ASD. Depleting these cells from the brain increased sociability, suggesting that targeting abnormal immune function during neurodevelopment may offer interventions for ASD.

This work is published in Science Immunology in the paper, “CXCL16-mediated recruitment of γδ T cells to the brain reduces sociability in mice.”

Infections during pregnancy can induce the release of interleukin-17A (IL-17A) from T helper 17 cells and γδ T cells. Prior research has linked this type of maternal immune activation to neurodevelopmental disorders, but there is a lack of evidence connecting IL-17A and social behaviors in genetic mouse models.

To investigate this further, a team of researchers from the Division of Allergy and Immunology in the Medical Institute of Bioregulation at Kyushu University, in Fukuoka, Japan, studied 15q11-13 duplication (15q dup) mice—a mouse model that mimics a chromosome duplication found in some humans with ASD. These mice also demonstrate reduced social interactions, behavioral inflexibility, and increased anxiety-like behaviors.

The team analyzed immune cell populations in the brains of the 15q dup mice. Their findings suggest an increase in γδ T cells in the developing brains when compared with wild-type mice.

Using single-cell RNA sequencing (scRNA-seq), the team uncovered that this was most likely due to microglia in the brain expressing the chemokine CXCL16, which promotes immune cell migration. CXCL16 was highly expressed in the brains of 15q dup mice and contributed to increased infiltration of γδ T cells.

In addition, experiments revealed that deleting IL-17A–producing γδ T cells or blocking them with antibodies after birth increased sociability and reduced anxiety-like behaviors in the 15q dup mice.

Taken together, the authors note that these findings suggest that “immune dysregulation contributes to social behavior deficits in 15q dup mice, consistent with observations in maternal immune activation models, and may represent a potential target for interventions for ASD-associated differences in social behavior.”
