Article Abstract
Background: Lack of motivation and behavioral abnormalities are the hallmarks of postpartum depression (PPD). Severe uterine contractions during labor are pain triggers for psychiatric disorders, including PPD in women during the puerperium. Creating biomarkers to monitor PPD may help in its early detection and treatment. It has been suggested that uterine contraction-induced labor pain plays a role in the emergence of this syndrome. Therefore, abnormal electroencephalography (EEG) patterns during the first stage of labor may provide useful information. Here, we propose that aberrant EEG patterns caused by painful uterine contractions may be predictive markers for PPD.
Methods: This study is a single-centre prospective cohort planned for 331 parturients for vaginal delivery in the maternity ward of Zhujiang Hospital from 2022 to 2023. At baseline, online or paper-based questionnaires, including the Edinburgh Postnatal Depression Scale (EPDS) and demographic data, will be collected when the parturient is admitted to labor. EEG, electrocardiography (ECG) and electrohysterography (EHG) signals will be monitored and recorded during the first stage of labor in the ward. Follow-up will be taken at the postpartum timepoints of day 3, day 42, and 3, 6 and 12 months, respectively. Power spectral density and functional connections will be quantified. The connections between PPD severity and EEG measurements as a function of time will be assessed using linear mixed-effects models. Maternal age, parity, and whether oxytocin is used during labor, all have an impact on the incidence of PPD, hence a stratified analysis will be carried out.
Discussion: We expect EEG changes caused by painful uterine contractions in the first labor may predict early PPD. The results from this study may act as a predictor for the development of PPD which may enhance long-term quality of life for the parturient and her offspring.
Trial Registration: Name of registry: EEG Alterations of Uterine Contractions in the First Stage of Labor Predicting PPD.

Dysmenorrhea refers to pathological symptoms that occur in association with menstruation during the menstrual period. Treatment options for dysmenorrhea include nonsteroidal anti-inflammatory drugs (NSAIDs) and low-dose estrogen-progestin combination pills. However, some patients do not respond to these treatments, and long-term use can lead to adverse reactions, raising additional problems.

The current article describes select nutritional metabolic disorders that can impact the health and well-being of beef and dairy cattle. These include: Subclinical or clinical acidosis that can lead to rumen, hind gut, or systemic acidosis. Acidosis can disrupt epithelial barrier function in the rumen and hindgut, enabling bacteria to enter the portal vein and form liver abscesses.

Cervical insufficiency (CI) is characterized by spontaneous dilation of the cervix in the absence of painful uterine contractions in the mid-trimester, leading to premature delivery. It is responsible for up to 20% of second trimester pregnancy losses, mostly <24 weeks. This life-threatening condition for the growing fetus faced during pregnancy is of complex etiology.

Background: Preterm labor is a common high-risk condition during pregnancy, but current diagnostic approaches, such as cervical length measurement and uterine contraction monitoring, lack sufficient specificity and sensitivity. This study aims to explore potential biomarkers for threatened preterm labor using untargeted metabolomics, providing novel indicators to improve clinical diagnosis.
Methods: A total of 46 pregnant women from Jiangxi Maternal and Child Health Hospital were retrospectively enrolled in case-control study and divided into a preterm birth group (n = 23) and a control group (n = 23) based on gestational age.
