Maternal Anxiety and Its Associated Factors During the First and Second Wave of COVID-19 Pandemic in Serbia: A Cross-Sectional Study.

Aim: The COVID 19-pandemic affects people differently, while pregnant women are among the most sensitive populations. The data about maternal mental health during the COVID-19 outbreak are in some ways consistent but also country-specific.

Purpose: The study aims to explore the impact of the COVID-19 pandemic on pregnant women's anxiety and identify its associated factors.

The Impact of Maternal Anxiety on Early Child Development During the COVID-19 Pandemic.

Maternal prenatal anxiety is among important public health issues as it may affect child development. However, there are not enough studies to examine the impact of a mother's anxiety on the child's early development, especially up to 1 year. The present prospective cohort study aimed to examine whether maternal trait anxiety, perceived social support, and COVID-19 related fear impacted speech-language, sensory-motor, and socio-emotional development in 12 months old Serbian infants during the COVID-19 pandemic.

Fetal Middle Cerebral Artery Pulsatility Index in No-Risk Pregnancies: Effects of Auditory Stimulation and Pregnancy Order.

Pulsatility index (PI) values in a fetal middle cerebral artery (MCA) were compared in no-risk pregnancies to examine the differences related to auditory stimulation test and pregnancy order. The study included 196 women with no-risk pregnancies selected from the database of more than 1000 pregnant women divided into two groups. Group 1 consisted of 98 nulliparous women (C1 = 98) and Group 2 consisted of 98 parous women (C2 = 98).

Correlation between maternal anxiety, reactivity of fetal cerebral circulation to auditory stimulation, and birth outcome in normotensive and gestational hypertensive women.

This study investigated the correlation between maternal anxiety and blood flow changes through the fetal middle cerebral artery (MCA) after defined acoustic stimulation in 43 normotensive (C) and 40 gestational hypertensive (GH) subjects. Neonatal outcomes (gestational age at birth, Apgar score, birth weight) in the C and GH groups were analyzed. State (STAI-S) and trait (STAI-T) anxiety was assessed using Spielberger's questionnaire.

Correlation between Balance Ability and Speech-Language Development in Children.

The longitudinal study was conducted in order to establish whether the success rate of reflexes related to maintaining balance at birth is in correlation with the success rate of maintaining balance in early childhood, as well as to examine the correlation of a certain level of speech and language development with the ability of maintaining balance at birth and at the age of 5. The main study group included 54 children of both genders, aged 5.0 to 5.

Fetus sound stimulation: cilia memristor effect of signal transduction.

Background: This experimental study evaluates fetal middle cerebral artery (MCA) circulation after the defined prenatal acoustical stimulation (PAS) and the role of cilia in hearing and memory and could explain signal transduction and memory according to cilia optical-acoustical properties.

Methods: PAS was performed twice on 119 no-risk term pregnancies. We analyzed fetal MCA circulation before, after first and second PAS.

Change of pulsatility index of the fetal middle cerebral artery after auditory stimulation in no risk pregnancies and in pregnancies with gestational hypertension.

Purpose: An aim was to determine the degree and the mode of variation of PI of middle cerebral artery in no risk pregnancies and in pregnancies with gestational hypertension, after the constant sound stimuli.

Method: Study included 343 patients divided in two groups. Group 1: low risk pregnancies and group 2: gestational hypertension.

Changes in Doppler blood flow velocity in middle cerebral artery in response to airborne sound in low- and high-risk human fetuses.

Objective: To examine fetal auditory perception in low- and high-risk pregnancies in period from 27 to 31 weeks gestational age with the aim to establish diagnostic parameters in prenatal detection of the degree of hearing development in a fetus.

Methods: Method of prenatal hearing screening was applied on 80 women divided in two groups: Control group (C=22), consisted of pregnant women with low-risk pregnancies, and Experimental group (E=58), consisted of pregnant women with high-risk pregnancies (pregnancies with diagnosis of: preterm delivery, hypertension and/or intrauterine growth restriction (IUGR), diabetes). PHS was applied in period from 27 to 31 weeks gestational age.

Comparison of mapping quantitative theta encephalograms during directed and required visual-verbal activity and passive period in children with different disorders of speech-language functioning.

Aim of the research was to examine similarities and differences between the periods of experiencing visually stimulated directed speech-language information and periods of undirected attention. The examined group comprised N = 64 children, aged 4-5, with different speech-language disorders (developmental dysphasia, hyperactive syndrome with attention disorder, children with borderline intellectual abilities, autistic complex). Theta EEG was registered in children in the period of watching and describing the picture ("task"), and in the period of undirected attention ("passive period").
