Neurobehavior of mexican newborns in conditions of low perinatal risk

INTRODUCTION: The first hours of life are still a window of opportunity to identify at-risk newborns, but there are few studies focusing on early neonatal behavior.OBJECTIVE: Describe in a cross section the behavior of newborns born in conditions of low perinatal risk under 48 hours of extrauterine life and compare it with historical referents.METHOD: We studied 47 newborns with low perinatal risk, whose behavior was assessed using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Scores were obtained by item and area, and then were compared with 7 historical referents.RESULTS: Low scores were found, both by item and by areas in up to 25% of the population. NBAS scores were related primarily with age of newborn, weight, and height. Significant differences were found in relation to referents for which higher scores were reported in the majority of cases.CONCLUSIONS: A pattern was found of behavior, in which the same areas or items caused greater or lesser difficulty in achieving higher scores or those which required a certain level of adaptation to the environment, which would lead us to believe that our newborns should attain the scores seen in other populations as they advance in age.

Predicting Patterns of Regulatory Behavior in the Still-Face Paradigm at 3 Months.

The current study addressed two aims: (1) to describe different patterns of infant regulatory behavior during the Face-to-Face Still-Face (FFSF) paradigm at 3months of age and (2) to identify specific, independent predictors of these patterns from an a priori set of demographic, infant (e.g., temperament), and maternal (e.g., sensitivity) variables. Analyses were based on data collected for 121 mother-infant dyads assessed longitudinally in the newborn period and again at 3months. In the newborn period, infants' neurobehavior was evaluated using the Neonatal Behavioral Assessment Scale (NBAS) and mothers reported on their caregiving confidence and their newborns' irritability and alertness. At 3months, mothers reported on their infant's temperament, and mother-infant interactions were videotaped during free play and the FFSF. Three patterns of infant regulatory behavior were observed. The most common was a Social-Positive Oriented Pattern, followed by a Distressed-Inconsolable Pattern, and a Self-Comfort Oriented Pattern. Results of multinomial logistic regression indicated that categorical assignment was not associated with demographic or infant characteristics, but rather with dyadic regulatory processes in which maternal reparatory sensitivity played a crucial role.

Effectiveness of Hammock Positioning in Reducing Pain and Improving Sleep-Wakefulness State in Preterm Infants.

Hammock positioning is now frequently used with preterm infants admitted to ICUs. However, few studies have investigated the extent to which hammock positioning reduces pain and improves the sleep-wakefulness state compared with traditional positioning. Twenty-six clinically stable newborns with gestational ages from 30 to 37 weeks who were breathing spontaneously were randomly assigned to 2 groups: a hammock-positioning group (n = 13), in which newborns were placed in hammocks in the lateral position, and a traditional-positioning group (n = 13), in which they were kept nested, also in the lateral position. The following variables were evaluated at the beginning and the end of the treatment: pain (with the Premature Infant Pain Profile, and Neonatal Facial Coding System), sleep-wakefulness state (with the Brazelton Neonatal Behavioral Assessment Scale), heart rate, breathing frequency, and peripheral SpO2 . The subjects in the hammock-positioning group showed an improvement in pain compared with the traditional-positioning group(Premature Infant Pain Profile score, 2.62 ± 1.89 vs 2.31 ± 1.97, ΔP = .008) and sleep-wakefulness state score (2.08 ± 0.64 vs 1.23 ± 0.44, Δ P < .001), reduced heart rate (151.69 ± 5.44 vs 142.77 ± 5.18 beats/min, Δ P < .001), breathing frequency (52.31 ± 4.05 vs 50.23 ± 2.55 beats/min, Δ P = .024), and increased peripheral SpO2 (94.69 ± 2.14 vs 98.00 ± 1.22%, Δ P < .001). Hammock positioning was an effective treatment option to reduce pain and improve sleep-wakefulness state. It also helped to reduce heart rate and breathing frequency, and to increase peripheral SpO2 , which made it a treatment option for preterm infants.

Preclinical modeling of exposure to a global marine bio-contaminant: Effects of in utero Domoic acid exposure on neonatal behavior and infant memory

Domoic Acid (DA) is a naturally-occurring marine neurotoxin that is increasingly recognized as an important public health issue. Prenatal DA exposure occurs through the maternal consumption of contaminated shellfish/finfish. To better understand the fetal risks associated with DA, we initiated a longitudinal, preclinical study focused on the reproductive and developmental effects of chronic, low-dose oral DA exposure. To this end, 32 adult female Macaca fascicularis monkeys were orally dosed with 0, 0.075 or 0.15 mg/kg/day DA on a daily basis prior to breeding and throughout breeding and pregnancy. The doses included the proposed human Tolerable Daily Intake (TDI) (0.075 mg/kg/day) for DA. Adult females were bred to nonexposed males. To evaluate development during early infancy, offspring were administered a Neonatal Assessment modeled after the human Neonatal Behavior Assessment Scale and a series of Visual Recognition Memory problems using the novelty paradigm. Results indicated that prenatal DA exposure did not impact early survival reflexes or responsivity to the environment. Findings from the recognition memory assessment, given between 1 and 2 months of age, showed that exposed and control infants demonstrated robust novelty scores when test problems were relatively easy to solve. Performance was not diminished by the introduction of delay periods. However, when more difficult recognition problems were introduced, the looking behavior of the 0.15 mg/kg DA group was random and infants failed to show differential visual attention to novel test stimuli. This finding suggests subtle but significant impairment in recognition memory and demonstrates that chronic fetal exposure to DA may impact developing cognitive processes.

Neonatal Behavioral Assessment Scale (NBAS): Confirmatory factor analysis of the six behavioral clusters

The Neonatal Behavioral Assessment Scale (NBAS) is a widely used in the neurobehavioral assessment of neonates in clinical practice and research. Lester's data reduction system for the NBAS items is the most often used in research, but the few factor analytic studies carried out with it leave gaps in its validation. The current study aimed to test and compare (a) the factorial structure of the Lester's data reduction system for the NBAS and (b) an alternative data reduction system, slightly modified from Lester's system. The NBAS was administered to 196 healthy Portuguese full-term infants (51% male) in the first 72 h of life (M = 43.63 h). Construct validity of the data reduction systems was tested through confirmatory factor analysis (CFA). Lester's original system was compared to three alternative models, two of which included a revision of the scoring rules for three items and the exclusion of five items. The CFA generally supported the six-factor structure. However, fit indices for Lester's original model were only fair. An alternative, revised model with a second-order factor – Self-Organizing System – demonstrated a better fit. The results provide evidence to support a modified form of Lester's six behavioral clusters as a data reduction model for the NBAS items.

Antenatal depression programs cortisol stress reactivity in offspring through increased maternal inflammation and cortisol in pregnancy: The Psychiatry Research and Motherhood – Depression (PRAM-D) Study

IntroductionAntenatal depression is associated with a broad range of suboptimal outcomes in offspring, although the underlying mechanisms are not yet understood. Animal studies propose inflammation and glucocorticoids as mediators of the developmental programming effect of prenatal stress on offspring stress responses, but studies in humans are not yet at this stage. Indeed, to date no single study has examined the effects of a rigorously defined, clinically significant Major Depressive Disorder (MDD) in pregnancy on maternal antenatal inflammatory biomarkers and hypothalamic-pituitary (HPA) axis, as well as on offspring HPA axis, behavior and developmental outcomes in the first postnatal year. MethodsA prospective longitudinal design was used in 106 women (49 cases vs. 57 healthy controls) to study the effect of MDD in pregnancy and associated antenatal biology (inflammatory and cortisol biomarkers), on offspring stress response (cortisol response to immunization, at 8 weeks and 12 months), early neurobehavior (Neonatal Behavioral Assessment Scale, NBAS, at day 6), and cognitive, language and motor development (Bayley Scales of Infant and Toddler Development at 12 months). ResultsCompared with healthy controls, women with MDD in pregnancy had raised interleukin (IL) IL-6 (effect size (δ) = 0.53, p = 0.031), IL-10 (δ = 0.53, p = 0.043), tumor necrosis factor alpha (δ = 0.90, p = 0.003) and vascular endothelial growth factor (δ = 0.56, p = 0.008), together with raised diurnal cortisol secretion (δ = 0.89, p = 0.006), raised evening cortisol (δ = 0.64, p = 0.004), and blunted cortisol awakening response (δ = 0.70, p = 0.020), and an 8-day shorter length of gestation (δ = 0.70, p = 0.005). Furthermore, they had neonates with suboptimal neurobehavioral function in four out of five NBAS clusters measured (range of δ = 0.45–1.22 and p = 0.049–<0.001) and increased cortisol response to stress at one year of age (δ = 0.87, p < 0.001). Lastly, maternal inflammatory biomarkers and cortisol levels were correlated with infant stress response, suggesting a mechanistic link. ConclusionThis study confirms and extends the notion that depression in pregnancy is associated with altered offspring behavior and biological stress response, and demonstrates that changes in maternal antenatal stress-related biology are associated with these infant outcomes.

Involvement of prolactin in newborn infant irritability following maternal perinatal anxiety symptoms

BackgroundNewborn irritability could be an unique and special status and/or adverse neurobehavioral outcomes which was independent of serious disease. To determine whether maternal perinatal anxiety symptoms was associated with newborn irritability, and whether the alteration of serum prolactin in newborns were involved in newborn irritability. Methods205 pregnant women were recruited: normal group (n = 100), and anxiety group (n = 105), which was randomly divided to Newborn Behavioral Observations (NBO)+anxiety group(n = 65) and control+anxiety group(n = 40). Newborn Irritability was assessed by Neonatal Behavioral Assessment Scale(NBAS). Serum prolactin, cortisol and 5-HT in mothers and infants were measured. Results1. The scores of irritability items in the newborns of anxiety group were higher than that of the normal group (p < 0.05). 2. Lower serum PRL, 5-HT and higher serum cortisol were found in the newborns of anxiety group compared with that of the control group both postpartum 2d and 15 (p < 0.05). 3. The level of serum PRL in newborn infants were significantly and negatively correlated to the scores of irritability items (p < 0.05). 4. After 7 rounds of NBO interventions, the anxiety scores of mothers and the scores of irritability items of newborns in the NBO intervention group were all lower than those of the control group (p < 0.05) . LimitationsIn future experiments, we should explore the effect of PRL in the breast milk on newborn infant serum PRL. ConclusionsProlactin could be a potential mediator in newborn irritability following maternal perinatal anxiety symptoms.

Neurobehavioral response to multisensory stimulation programme in high-risk neonates

Context High-risk neonates admitted to the neonatal intensive care unit (NICU) are suffering from lack of sensory experiences that are vital for normal brain development, rather are exposed to excessive or inappropriately timed stimulation in the NICU that leads to deleterious effects on premature infants whose brains are immaturely developed. Aim The aim of this study was to investigate the effect of multisensory stimulation programme on neurobehavioral development in high-risk neonates. Settings and design A prospective randomized controlled trial was conducted on 40 high-risk neonates, who were selected from NICUs, with mean gestational age of33±1.03 weeks according to new Ballard score and mean weight 1442±228.5 g. They were allocated into either the control group or the study group. Participants and methods The control group received routine medical and nursery care in the NICU, whereas the study group received the same programme given to the control group in addition to the multisensory stimulation programme given daily for 2 successive weeks. The outcomes were measured before and after the intervention by Morgan neonatal neurobehavioral examination and Brazelton neonatal behavioural assessment scale. Results There was a significant improvement in all measured variables in the study group after the intervention programme (P Conclusion Multisensory stimulation improved neurobehavioral development in high-risk neonates. This could be a vital part of the routine neonatal physiotherapy for preterm and high-risk neonates.

The Brazelton Neonatal Behavioral Assessment Scale: A validity and reliability study in a Turkish sample

Background/aim: The aim of the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) is to gather a comprehensive profile of neonatal functioning by describing the full range of neonatal behavior, including competencies and strengths, as well as difficulties or deviations. This instrument has proved to be of great clinical value by detecting infants at risk for later developmental problems. This work was conducted methodologically with the aim of a Turkish validity and reliability study of the BNBAS. Materials and methods: The study was conducted in a large tertiary hospital in Turkey. After establishing content and language validity, the BNBAS was applied to 380 newborns aged 1–3 days and test–retest analysis was performed for 60 newborns 52–55 days later in the first phase. The validity and reliability study of the BNBAS included behavior and support subscales, while reflex items were not included. Results: In the study, 5 items were excluded from the original BNBAS after the factor analysis. Cronbach alpha was found as 0.974 (30 items). The behavior subscale consisted of 23 items and the support subscale consisted of 7 items. Newborns showed good overall tone and activity level and low amounts of irritable behavior. Conclusion: It may be recommended to use the BNBAS as a valid and reliable measurement tool in neonatal behavioral evaluation by physicians and nurses.

Effects of hammock positioning in behavioral status, vital signs, and pain in preterms: a case series study

BackgroundThe hammock positioning within the incubators simulates the intrauterine environment, however, there is little evidence of its benefits and possible risks. ObjectivesThe aim of this study was to assess the effects of hammock positioning on behavioral status, vital signs, and pain in very low birth weight preterm newborns. MethodsThis is a quasi-experimental/case series study in which premature infants (<1500g) were positioned in supine for one hour in a hammock. The preterm newborns were assessed 10min before, during (2, 20, 40, and 60min), and 10min after hammock positioning with the Brazelton Neonatal Behavioral Assessment Scale, vital signs and pain by the Neonatal Facial Coding System. Results28 preterm infants between 28 and 36 weeks of gestational age were evaluated. Regarding the behavioral state, the preterm newborns progressively evolved to light or deep sleep during hammock positioning. There was a statistically significant reduction of the heart and respiratory rate from 2 to 60th minute in a hammock, which was maintained after the positioning. The oxygen saturation remained within normal values. No changes in pain scores were observed. ConclusionThe hammock positioning can be considered a safe method of positioning that can be used to reduce the stress levels in very low birth weight preterm newborns. We did not observe worsening in either pain or vital signs.

The Neonatal Behavioral Assessment Scale (NBAS) and Newborn Behavioral Observations (NBO) system for supporting caregivers and improving outcomes in caregivers and their infants.

The first three years of a child's life are a key period of physical, physiological, cognitive and social development, and the caregiver-infant relationship in early infancy plays an important role in influencing these aspects of development. Specifically, caregiver attunement facilitates the move from coregulation to self-regulation; a parent's ability to understand their infant's behaviour as communication is a key part of this process. Early, brief interventions such as the Neonatal Behavioral Assessment Scale (NBAS) or Neonatal Behavioral Observation (NBO) system are potential methods of improving outcomes for both infant and caregiver. To assess the effects of the NBAS and NBO system for improving caregiver-infant interaction and related outcomes in caregivers and newborn babies. Secondary objectives were to determine whether the NBAS and NBO are more effective for particular groups of infants or parents, and to identify the factors associated with increased effectiveness (e.g. timing, duration, etc.). In September 2017 we searched CENTRAL, MEDLINE, Embase, PsycINFO, 12 other databases and four trials registers. We also handsearched reference lists of included studies and relevant systematic reviews, and we contacted the Brazelton Institute and searched its websites to identify any ongoing and unpublished studies. We included randomised controlled trials (RCTs) and quasi-RCTs that had used at least one standardised measure to assess the effects of the NBAS or NBO versus inactive control for improving outcomes for caregivers and their infants. Two reviewer authors independently assessed the records retrieved from the search. One reviewer extracted data, and a second checked them for accuracy. We presented the results for each outcome in each study as standardised mean differences (SMDs) or as risk ratios (RR) with 95% confidence intervals (CIs). When appropriate, we combined the results in a meta-analysis using standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the overall quality of the body of evidence for each outcome. We identified and included 16 RCTs in this review: 13 assessing the NBAS and 3 the NBO for improving outcomes in 851 randomised participants, including parents and their premature or newborn (aged 4 to 12 weeks) infants. All studies took place in the USA, and we judged all of them to be at high risk of bias.Seven studies involving 304 participants contributed data to one meta-analysis of the impact of the NBAS or NBO for caregiver-infant interaction, and the results suggest a significant, medium-sized difference between intervention and control groups (SMD -0.53, 95% CI -0.90 to -0.17; very low-quality evidence), with moderate heterogeneity (I2 = 51%). Subgroup analysis comparing the two types of programmes (i.e. NBAS and NBO) found a medium but non-significant effect for the NBAS (-0.49, 95% CI -0.99 to 0.00, 5 studies), with high levels of heterogeneity (I2 = 61%), compared with a significant, large effect size for the NBO (-0.69, 95% CI -1.18 to -0.20, 2 studies), with no heterogeneity (I2 = 0.0%). A test for subgroup differences between the two models, however, was not significant. One study found a significant impact on the secondary outcome of caregiver knowledge (SMD -1.30, 95% CI -2.16 to -0.44; very low-quality evidence). There was no evidence of an impact on maternal depression. We did not identify any adverse effects. There is currently only very low-quality evidence for the effectiveness of the NBAS and NBO in terms of improving parent-infant interaction for mostly low-risk, first-time caregivers and their infants. Further research is underway regarding the effectiveness of the NBO and is necessary to corroborate these results.

Efficacy of Early Yakson Touch and Kinaesthetic Stimulation (Yakin) on the Development of High Risk Neonates: A Randomized Controlled Trial Protocol

Introduction: About 15 million babies are born preterm annually, with every year almost 1 million dying from complications and survivors prone to lifetime disability. Yakson touch and kinaesthetic stimulation techniques have proven effective in minimizing the complications and disability of preterm delivery, but presently there is no standardized protocol for their application. The aim is to investigate the efficacy of Yakson touch in combination with kinaesthetic stimulation (YAKIN) on the motor and behavioural development of neonates at high risk of development delay in comparison to conventional handling.Material and Methods: Neonates will be recruited via parental consent from a recognized tertiary care teaching hospital for this two-group pretest-posttest design of randomized controlled trial (RCT), with allocation into either a control group (n=14) or experimental group (n=14) by block randomization method. The experimental group will receive Yakson touch and kinaesthetic stimulation, whilst the control group will receive conventional handling inclusive of developmental positioning and Kangaroo mother care. The duration of intervention will be five out of seven days. Neonatal behavioural assessment scale (NBAS) will be performed at baseline and then on the 7th day to ascertain the intervention effectiveness.Results: Data analysis will be done by Wilcoxon signed rank test/paired t-test and Mann Whitney U test/independent t-test will be done to compare the pre and post intervention score of NBAS within and between groups. The level of significance will be set as p&lt;0.05.Conclusion: The present study may provide valuable information about early intervention to the neonatal physiotherapist, intensivist, nursing staff and parents of neonates.

Yakson touch and kinesthetic stimulation on development of high-risk neonates in neonatal intensive care units: A randomized controlled trial

Background and Objectives: About 15 million babies are born preterm every year. Among them, almost 1 million neonates die due to complications. Even the survivors are prone to lifetime disability. Yakson touch and kinesthetic stimulation techniques have been proved to be effective in minimizing the complications and disability, but there is no standardized protocol. Hence, we aimed to investigate the efficacy of Yakson touch in combination with kinesthetic stimulation (YAKIN) on the development of high-risk neonates. Materials and Methods: Twenty-eight neonates were recruited through parental consent from a recognized tertiary care teaching hospital for this two-group pre- and post-test design of randomized controlled trial and were allocated into control group (n = 14) and experimental group (n = 14) by block randomization method. Neonatal behavioral assessment scale (NBAS) was performed on all recruited neonates. The duration of intervention was 5 days out of 7 days. The experimental group received Yakson touch and kinesthetic stimulation and the control group received conventional handling which included developmental positioning and Kangaroo mother care. On the 7th day, NBAS was done again to document the effect of the intervention. Results: Neonates median gestational age of 35 (34, 35.3) weeks in experimental and 35 (33.5, 36) in control group were recruited. There were no significant differences between the groups (p> 0.05). Large effect size index was seen in the experimental group. Conclusions: Efficacy of the standardized protocol YAKIN has been verified, and it may have positive effects on the overall development of high-risk neonates.

Clinical application of the Standard Operating Procedure of Positioning with Premature Infants.

To compare the physiological and behavioral responses of Premature Infant (PREEMIE) positioned by the Unit Routine Decubitus (URD) and the Standard Operating Procedure (SOP). A quasi-experimental comparative study performed at a Neonatal Intensive Care Unit in Southern Brazil. We evaluated 30 PREEMIEs with gestational age ≤32 weeks, randomly assigned to Unit Routine Decubitus (URD) and Intervention Group (IG), subdivided into Right Lateral Decubitus (RLD), Dorsal Decubitus (DD), Left Lateral Decubitus (LLD) and Ventral Decubitus (VD). It was evaluated before, during and after the procedure: Heart Rate (HR); Respiratory Frequency (RF); Peripheral Oxygen Saturation (SpO2); behavior by the Neonatal Behavioral Assessment Scale (NBAS); by NIPS. During the intervention, RR (p = 0.023), indexes in NBAS (p = 0.01) and NIPS (p <0.0001) reduced significantly in SOP. HR and SpO2 did not present a significant difference. Positioning according to the SOP shows benefit in relation to the behavioral and physiological status of PREEMIE.

Vagal modulation of 1‐month‐old infants to auditory stimuli is associated with self‐regulatory behavior

AbstractDuring infancy, cardiac vagal modulation has been associated with attentional and social engagement behaviors. While studies have shown that infants display a behavioral repertoire that enables them to interact with others by being able to regulate themselves in order to attend to and to discriminate emotional and social cues, vagal modulation to sensory stimuli and its association with behavioral outcomes at early ages remains to be addressed. In this study, we analyzed the cardiac vagal response of 1‐month‐old infants to two auditory stimuli intensities and whether vagal response was associated with social interactive and self‐regulatory abilities. Therefore, we recorded cardiac and respiratory physiological responses in 28 infants using a Biopac System. Neurobehavioral assessment was performed using the Neonatal Behavioral Assessment Scale. We observed increased respiratory sinus arrhythmia (RSA) amplitude to both auditory stimuli intensities when compared to baseline. No intensity effect was found for the RSA response. Additionally, we observed that higher RSA amplitude to both auditory stimuli was positively correlated with adjusted self‐regulatory behaviors, suggesting a convergence between multiple measures assessing infants' state regulation. Results are discussed in light of 1‐month‐old infants' auditory stimuli processing and its implications for regulatory behaviors and the emergent social‐like behaviors.

Clinical value of transfontanellar ultrasonography for neonatal insular development

Objectives: The aims of this study were to assess the morphological characteristics and to establish ultrasonographic standards of normal neonatal insula size using transfontanellar ultrasonography, and to evaluate the clinical value of this technique. Materials and Methods: The authors performed transfontanellar ultrasonography in 481 single-birth cases at 28-43 weeks’ gestation. Ultrasonographic examinations were performed in the parasagittal plane at the level of the insula through the anterior fontanelle, measuring area, and perimeter of the insula. Regression analyses were used to evaluate the relationship between insula size and gestational age (GA), and 60 cases were randomly selected for assessment of intra-observer and inter-observer reliability of ultrasonographic measurements. The authors obtained standard values of normal insula size and used them to assess and follow-up 40 cases with suspected insular malformations. Additionally, 30 late-onset neonates who were determined as small for gestational age (SGA) and 45 normally growing neonates were examined and tested using the Neonatal Behavioral Assessment Scale (NBAS). Results: The neonatal insula appeared as an inverted triangle, with the insular gyri extending radially in an anterior-inferior to posterior-superior direction. The area and perimeter of the normal neonatal insula significantly increased with GA (p Conclusion: Evaluation of the neonatal insula using transfontanellar ultrasonography can be performed and is clinically useful.

Limited effects of pre‐existing maternal antisocial behaviours on infant neurodevelopment: A pilot study

AbstractAntisocial behaviour disorders (ABDs) are among the most costly and treatment resistant of all psychiatric syndromes. Select neurodevelopmental abnormalities have been labelled a risk factor for ABDs, but it is unknown if maternal ABDs are associated with early neurodevelopmental abnormalities. This study tested whether infants of ABD mothers had more neurodevelopmental abnormalities than mothers with no psychiatric disorder (ND). Thirty‐nine pregnant women (49% with ABDs; 51% no psychiatric disorder) were recruited from the community. Infant neurodevelopment was assessed at ≤1 and 8 weeks using the Neonatal Behavioural Assessment Scale and at 16 weeks of age using the Bayley Scales of Infant and Toddler Development‐III. There was no significant group difference at ≤8 weeks. At 16 weeks, ABD mothers rated their infants higher on the Adapted Behaviours subscale, specifically on the leisure and self‐directed scales, when corrected for substance use and socio‐economic status. This pilot study found higher maternal ratings of Adapted Behaviours at 16 weeks, which may be due to unrealistic expectations about infant development.Highlights Maternal Antisocial behaviour disorders (ABDs) do not impact early infant neurodevelopment at ≤ 8 weeks old as measured by standardized assessment. Mothers with ABDs view their infants at 16 weeks as better adapted than women without any psychiatric disorder. Specifically, mothers with ABDs reported their infants as better adapted on the leisure and self‐direction subscales of the Bayley Scales of Infant and Toddler Development‐III. This finding may be due to less knowledge about normal infant adaptive behavior.

A pilot study of maternal exposure to organophosphate pesticides and newborn neurodevelopment in Thailand.

The objective of this study was to evaluate whether prenatal exposures to organophosphate (OP) pesticides from maternal agricultural use are associated with neonatal neurobehavioral effects. A pilot study conducted in three provinces in Thailand measured maternal urinary metabolites of OP pesticides in pregnant women at 7months gestation and at birth. Within 3days of birth, 82 newborns underwent neurobehavioral testing using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Comparison of the NBAS test results with maternal OP metabolite levels found the neonates NBAS Habituation cluster score increased with maternal dimethylphosphate (DMP) levels (p=0.04) while the Range of State score increased with total diethylphosphate (DEP) levels (p=0.01). The Number of Abnormal Reflexes in the neonate also increased as maternal urinary total DEP levels increased (p=0.06). These preliminary findings suggest that pre-natal exposures to OP pesticides can impact newborn neurodevelopment and support the need for a longitudinal evaluation of childhood neurodevelopment in relation to pesticide exposures in Thailand.
