AI Article Synopsis
- This study investigates how maternal mood disorders affect fetal activity as measured by the nonstress test during the third trimester of pregnancy.
- Researchers compared results from pregnant individuals with and without mood disorder symptoms, using validated screening tools for depression and anxiety.
- Findings showed no significant differences in key nonstress test metrics, indicating that maternal mood does not significantly influence fetal heart rate patterns or activity levels.
Article Abstract
Background: Previous studies have suggested that acute mood states may influence levels of fetal activity. Because the fetal nonstress test relies on markers of fetal activity to suggest fetal wellbeing, its interpretation may be affected by maternal mood.
Objective: This study sought to determine if there are differences in nonstress test characteristics between pregnant individuals with and without symptoms of mood disorder.
Study Design: In this prospective cohort study, we recruited pregnant individuals undergoing nonstress test in the third trimester and compared the results of the nonstress test between pregnant individuals with scores above and below the cutoff values on validated screening questionnaires for depression and anxiety symptoms, the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder 7-item scale (GAD-7). Demographic information was collected from each participant at the time of recruitment, and medical information was extracted from the electronic medical record.
Results: A total of 68 pregnant individuals were enrolled, 10 (15%) of which screened positive for perinatal mood disorders. There was no significant difference in means of time to reactivity (15.6 [4.8] minutes vs 15.0 [8.0] minutes, P=.77), number of accelerations (0.16/min [0.08] vs 0.16/min [0.10], P>.95), number of fetal movements (17.0 [14.7] vs 19.7 [20.4], P=.62), heart rate baseline (138.0 [7.5] bpm vs 139.2 [9.0] bpm, P=.67) or variability (8.5 [2.5] bpm vs 9.1 (4.3) bpm, P=.51) between pregnant individuals who screen positive for mood disorders and those who did not.
Conclusion: Fetal heart rate patterns are similar in pregnant individuals with and without symptoms of mood disorder. The results provide reassurance that acute symptoms of anxiety and depression do not have significant effects on the fetal nonstress test.

Osteoporosis (OP) is a common clinical bone disease that can cause a high incidence of non-stress fractures and is one of the main degenerative diseases that endangers the health and life of middle-aged and older women. The mechanism underlying the abnormal differentiation and function of human bone marrow stem cells (hBMSCs) remains to be elucidated. Cell proliferation and differentiation were determined using 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay, alkaline phosphatase (ALP) staining, and Alizarin Red Staining.

Introduction: Early adolescence is a time of high psychosocial stress exposure and high stress reactivity, associated with the development of mental disorders. Understanding how the brain reacts to acute and social stressors during this period might help us detect and protect those at risk.
Methods: We used functional magnetic resonance imaging to investigate acute social stress reactivity in non-clinical adolescents between ages 13 and 15 years (N = 61) with a range of depression scores (Beck Depression Inventory scores 0-32).

Objective: The aim of this research was to determine the effect of music on nonstress testing and pregnant women's satisfaction.
Methods: The research, which was designed as a randomized controlled experimental study, was conducted between September 2021 and September 2022 at a training and research university hospital in the north of Turkey. The population of the research consisted of pregnant women who were requested to take a nonstress test, and the sample consisted of 111 pregnant women (music group: 56 and control group: 55).
