Fetal Health Locus of Control, Maternal Anxiety, and Cardiotocography in High-Risk Pregnancies

This prospective observational cross-sectional study aims to evaluate the relationships among fetal health locus of control (FHLC) perceptions, maternal anxiety levels, and fetal cardiotocography parameters in high-risk pregnant women. Pregnant women at 32 weeks of gestation or later who undergo routine non-stress testing (NST) at the Perinatology Outpatient Clinic will be invited to participate. On the same day as the routine NST, participants will complete the Fetal Health Locus of Control Scale and the Beck Anxiety Inventory. Associations between FHLC dimensions, maternal anxiety levels, and NST parameters, including baseline fetal heart rate, number of accelerations, reactivity, and presence of decelerations, will be evaluated.

Mandala Coloring, Stress, and Anxiety

\*\*Abstract\*\* Although pregnancy is a physiological process, it also involves various risks that may threaten the health of both the mother and fetus. Complications arising in high-risk pregnancies and prolonged bed rest increase stress and anxiety levels in women, negatively affecting both physical and psychological well-being. Failure to recognize or appropriately manage these adverse conditions may lead to serious perinatal outcomes such as preterm birth, low birth weight, depression, and difficulties in mother-infant bonding, thereby creating an additional burden on both maternal-infant health and the healthcare system. This proposed project aims to examine the effect of mandala coloring activity on perceived stress and anxiety in women with high-risk pregnancies. The study will be conducted as a randomized controlled experimental study with a pretest-posttest design. The population of the study will consist of pregnant women hospitalized in the Obstetrics and Gynecology service of Kahramanmaraş Sütçü İmam University Health Practice and Research Hospital. Based on power analysis, with a significance level of α = 0.05 and statistical power of (1-β) = 0.80, at least 26 participants per group were required assuming a large effect size (Cohen's d ≈ 0.80). Considering potential sample loss, 30 participants were planned for each group, resulting in a total sample size of 60. Before data collection, ethics committee approval and institutional permission will be obtained. Data will be collected using the Personal Information Form, the Perceived Stress Scale in Risky Pregnancies Based on the Neuman Systems Model, and the State Anxiety Inventory. Pregnant women in the experimental group will participate in mandala coloring once daily for three consecutive days. Stress and anxiety levels will be assessed before and after the intervention using the relevant scales. In addition to descriptive statistical methods, appropriate statistical tests will be used according to normality assumptions. The methods specified in the project will be carried out by the principal investigator under the supervision of the advisor. The project is expected to demonstrate that mandala coloring is effective in reducing stress and anxiety in women with high-risk pregnancies. In line with the goals emphasized in Türkiye's 12th Development Plan regarding innovative healthcare practices and strengthening public health, the findings are expected to contribute to the protection of maternal and infant health and the promotion of psychological well-being. Furthermore, by supporting reductions in medication use, length of hospital stay, and healthcare costs, the project may contribute to the dissemination of cost-effective, accessible, and holistic care approaches within the healthcare system. Mandala coloring is an easily applicable, side-effect-free, and low-cost method that does not require special equipment, technical expertise, or a professional art therapist. In this respect, it represents a sustainable non-pharmacological intervention that can be easily implemented by nurses in both hospital settings and community-based healthcare services, with almost no training or material costs. Therefore, the findings of this project are expected to support not only individual-level psychological relaxation but also the development of cost-effective, innovative, and accessible care models in healthcare services. The project outcomes are also expected to strengthen the holistic care approach in nursing and promote the integration of non-pharmacological interventions into clinical protocols. The findings of the study will be published in scientific journals and presented at national and international congresses. In addition, this research will contribute to the literature and provide a basis for the development of more comprehensive future projects. One of the most important outcomes of this research is that it will enable an undergraduate student to gain experience in conducting research, interpreting results, and preparing for publication, thereby contributing to the training of qualified researchers in priority areas of our country.

Leg Heating in Pregnant Women With Obesity

Obesity is a major risk factor for hypertensive disorders of pregnancy (HDP). The underlying mechanisms are largely unclear, but maternal vascular endothelial dysfunction is likely involved. Endothelial dysfunction in HDP could be attributed to 1) alterations in the L-arginine/nitric oxide (NO) pathway, and 2) an increase in endothelin-1 (ET-1). Additionally, augmented sympathetic vasoconstriction may also contribute to HDP. Chronic (repeated) whole-body heat exposure has been shown to increase NO bioavailability, decrease ET-1, and cause functional and structural adaptations in the vasculature. All these can improve vascular function, attenuate sympathetic (re)activity, lower blood pressure (BP), and reduce cardiovascular risk in non-pregnant individuals. Whether this is also true after regional (leg) heating in high-risk pregnant women is unknown. The investigators' central hypothesis is that chronic leg heating will be effective in improving vascular endothelial function and attenuating sympathetic vasoconstriction, leading to a reduction of the risk for HDP in pregnant women with obesity. The overarching goal of this proposal is to determine the vascular and neural effects of chronic leg heating in obese pregnancy. The study team plans to enroll pregnant women with obesity between 12-14 weeks of gestation and randomly assign them to either an intervention group or a control group (1:1 ratio). Participants in the intervention group will perform 16 weeks of home-based leg heating using a portable sauna blanket up to the hip (temperature of the blanket will be set at 65°C, 4 times/week, 45 min/session), whereas women in the control group will set the temperature of the blanket at 35°C at the same frequency and duration. Participants will be evaluated at baseline and then at 28-30 weeks of gestation. Aim 1 will determine the effects of chronic leg heating on maternal vascular function and surrogate markers of HDP. Aim 2 will determine the effects of chronic leg heating on sympathetic vasoconstriction and BP. Findings from this project will provide insight on the extent and potential mechanisms of how chronic leg heating works for improving vascular endothelial function and sympathetic vasoconstriction in pregnant women with obesity. Results obtained will set a foundation for future large multicenter clinical trials to determine the efficacy and generalizability of home-based leg heat therapy as a safe, ease-of-use, cost-effective, and non-drug approach for reducing the risk of HDP.

Effect of Hypnobreastfeeding Education in High-Risk Pregnant Women

It is thought that hypnobreastfeeding training given to high-risk pregnant women will reduce anxiety levels, increase lactation, encourage breastfeeding, reduce the perception of insufficient milk, and facilitate adaptation to the postpartum breastfeeding process. According to the results of the power analysis, at least 68 high-risk pregnant women, 34 experimental and 34 control, should be included in the study. Data will be collected with the "Pregnancy Information Form", "Anxiety Assessment Scale", " Infant Feeding Intention Instrument", "Postpartum Information Form", "Perception of Insufficient Milk Questionnaire" and "Breastfeeding Adaptation Scale". In the research, hypnobreastfeeding training will be applied by the researcher to the high-risk pregnant women in the experimental group.

AI-Powered CURAᵀᴹ Application for Identifying At-Risk Pregnancies in Obstetric Management

It is important to identify high pregnancies early through screening so that appropriate care and intervention may be instituted. An AI-assisted risk categorisation approach may be advantageous compared with traditional means of screening. The purpose of this study is to determine if the adoption of an AI-assisted approach in general pregnancy risk screening will improve the accuracy of antenatal risk categorization into high- and low- risk pregnancy groups, ultimately resulting in fewer poor maternal and fetal/neonatal outcomes.
