Obstetric Exercise and Maternal Outcomes in Pregnancy

This randomized controlled trial will be conducted in the antenatal clinic and pregnancy school of a public hospital in eastern Türkiye. The study will aim to investigate the effects of a structured obstetric exercise program on pregnancy-related symptoms and their impact on daily functioning, as well as depressive symptoms, in women receiving prenatal care. A total of 100 pregnant women will be recruited and randomly assigned to either the intervention group (n=50) or the control group (n=50). The intervention group will participate in a four-week, physiotherapist-led, supervised obstetric exercise program, while the control group will continue to receive routine prenatal care. Data will be collected using a sociodemographic questionnaire, the Pregnancy Symptoms Inventory (PSI), and the Beck Depression Inventory (BDI). The primary outcome will be pregnancy-related symptom burden assessed using the PSI total score, and the secondary outcome will be self-reported depressive symptom severity assessed using the BDI. This study is expected to contribute to the evidence base by clarifying the potential role of structured obstetric exercise in reducing pregnancy-related symptom burden and depressive symptom severity during the third trimester.

Treatment With Repetitive Transcranial Magnetic Stimulation in Peripartal Depression

The goal of this clinical trial is to learn whether repetitive transcranial magnetic stimulation (rTMS) can reduce depressive symptoms in women who are pregnant or up to 12 months after childbirth and have peripartum depression. rTMS is a non-invasive treatment in which a device placed on the scalp delivers gentle magnetic pulses to a brain area involved in mood regulation. It does not involve medication or anaesthesia. The main questions this study aims to answer are: * Does active rTMS reduce depressive symptoms more than sham rTMS? * What side effects occur during treatment, and how well is rTMS tolerated? * Are improvements in depressive symptoms still present one month after treatment? Researchers will compare active rTMS with sham rTMS, a treatment designed to feel and sound similar but not to provide effective brain stimulation. Neither participants nor the clinicians assessing depressive symptoms will know which treatment was assigned during the main study phase. Up to 60 women aged 18 years or older who are pregnant or up to 12 months after childbirth and have clinically relevant depressive symptoms may take part. Participants will: * Attend a screening and baseline visit, including questionnaires, EEG and ECG recordings, and collection of small hair and sputum samples to study stress-related hormone levels * Be assigned by chance to receive either active rTMS or sham rTMS * Attend 30 treatment sessions, scheduled flexibly over approximately 1.5 to 10 weeks to accommodate childcare, breastfeeding, fatigue, and medical appointments * Complete questionnaires about mood, wellbeing, quality of life, social support, and treatment expectations before and after treatment * Have safety and side effects checked before each treatment session * Complete a telephone follow-up assessment one month after treatment * Be asked to complete a short questionnaire about their child's development one year after treatment Each treatment visit lasts about 30 minutes, including preparation, treatment, and a short safety check. Infants may be brought to treatment visits when this can be done safely. rTMS is generally well tolerated. Possible temporary side effects include headache, scalp discomfort, facial muscle twitching during stimulation, dizziness, or tiredness. A seizure is a very rare but serious possible risk; therefore, people with epilepsy, certain implants, or other relevant risk factors cannot take part. Participation is voluntary. Participants can pause or stop participation at any time without affecting their usual care. Personal data will be coded and handled confidentially. Women assigned to sham treatment will be offered active rTMS after the blinded study phase, if they wish. The results may help clarify whether rTMS is an effective non-medication treatment option for peripartum depression.

The Association Between Gut Microbiota Diversity and Postpartum Depression

This study aims to examine whether naturally occurring bacteria in the gastrointestinal tract are associated with mood changes following childbirth, including postpartum depression. Biological samples will be collected before and after delivery to determine whether specific patterns in gut bacterial composition are linked to emotional states. The purpose of the research is to improve understanding of whether such microbial changes can help identify individuals at higher risk for postpartum depression, enabling earlier recognition and intervention.

IMAGINE: Pilot Trial of a Digital Group Intervention to Prevent Perinatal Depression

The goal of this clinical trial is to evaluate if a digital group intervention (named IMAGINE) can prevent depression in perinatal populations. The main questions it aims to answer are: Does IMAGINE engage cognitive behavioral therapy targets? Does IMAGINE lead to lower depression scores? Is IMAGINE acceptable, appropriate, usable and feasible? Participants will be randomized to either participate in an IMAGINE group for 12 weeks or receive standard of care. Participants will respond to questionnaires at enrollment and study visits at 12 and 24 weeks after enrollment.

Virtual Reality-enhanced Psychotherapy for Perinatal Depression

Perinatal depression is a growing public health crisis in the United States, affecting one in five individuals during pregnancy or postpartum. Mental health conditions contribute to 23% of maternal deaths, underscoring the urgent need for innovative interventions. Obstetric patients who experience complications requiring prolonged hospitalization are particularly vulnerable to mental health deterioration. Virtual reality (VR) has shown promise for expanding access, reducing barriers, and enhancing first-line depression treatment when paired with evidence-based psychotherapies such as behavioral activation (BA). However, traditional BA is not feasible for inpatients, as their hospitalization prevents participation in conventional in-person, mood-boosting activities; VR-enhanced BA (VR-BA) presents a novel opportunity to address this gap. The goal of the study is to compare a 3-week VR-BA protocol to standard therapy (social work consultation) for hospitalized pregnant individuals with depressive symptoms. The objectives are to assess 1) whether VR-BA is acceptable, tolerable, and feasible in this population and 2) whether it leads to greater reductions in depressive symptoms compared to standard therapy.

Prevention of Mother-to-child Transmission (PMTCT) Among Women Experiencing Depression in Malawi

Prevention of mother-to-child transmission (PMTCT) of HIV virtually eliminates transmission of HIV from mothers to their infants. Adherence to PMTCT (i.e., to antiretroviral therapy, infant prophylaxis, and exclusive breastfeeding) during pregnancy and the postpartum period is challenging, with evidence from sub-Saharan Africa (SSA) showing suboptimal adherence and persistent viremia among perinatal women. Perinatal depression (PD) is a major driver of women's poor adherence to PMTCT. Interventions that involve male partners to provide social and food/economic support could be a promising approach for addressing PD and PMTCT, yet few interventions have intervened with couples to improve systems of support, communication, and other dyadic processes. The investigators propose to develop and test a couple-based approach to intervene on the mother's perinatal depressive symptoms and to strengthen the relationship and support system for partners to work together around depression to improve PMTCT adherence. The study will take place in antenatal and HIV care settings in Zomba, Malawi. The specific aims are: (1) to develop a couple-based intervention to target perinatal depression (PD) based on an evidence-based approach using problem-solving therapy (PST), augmented with content on couple communication and problem-solving skills; and (2) to assess the feasibility and acceptability (F\&A) of the intervention via a pilot randomized controlled trial (RCT). Our short-term goal is the produce a couple-focused PST intervention that can be added to the global health toolkit for treating depression in perinatal women. Our long-term goal is to produce a high-impact and sustainable intervention leveraging the couple relationship that can be scaled-up to address depression, PMTCT adherence, and family health.
