Genetic Markers Associated with Postpartum Depression: A Review.

Postpartum depression (PPD) is a common illness in mothers after childbirth. PPD negatively affect the mother's quality of life and the bond with the infant, which can interfere with the infant's emotional, social, and cognitive development. PPD is caused by various biological and psychosocial factors. The aim of this review is to summarize the latest evidence of the associations between genetic polymorphisms and PPD. PubMed and Scopus were used as the literature search databases for this review. The keywords used were postpartum depression, postnatal depression, genetic, and polymorphism. Twenty-seven articles were reviewed after screening and applying the inclusion criteria. As results, the serotonin gene (5-HTTLPR) and oxytocin genes (OXTR) have the most significant associations with PPD among other genes. Further research on PPD biomarkers should be conducted to diagnose and treat PPD patients.

Automated Prediction of Infant Cognitive Development Risk by Video: A Pilot Study.

Cognition is an essential human function, and its development in infancy is crucial. Traditionally, pediatricians used clinical observation or medical imaging to assess infants' current cognitive development (CD) status. The object of pediatricians' greater concern is however their future outcomes, because high-risk infants can be identified early in life for intervention. However, this opportunity has not yet been realized. Fortunately, some recent studies have shown that the general movement (GM) performance of infants around 3-4 months after birth might reflect their future CD status, which gives us an opportunity to achieve this goal by cameras and artificial intelligence. First, infants' GM videos were recorded by cameras, from which a series of features reflecting their bilateral movement symmetry (BMS) were extracted. Then, after at least eight months of natural growth, the infants' CD status was evaluated by the Bayley Infant Development Scale, and they were divided into high-risk and low-risk groups. Finally, the BMS features extracted from the early recorded GM videos were fed into the classifiers, using late infant CD risk assessment as the prediction target. The area under the curve, recall and precision values reached 0.830, 0.832, and 0.823 for two-group classification, respectively. This pilot study demonstrates that it is possible to automatically predict the CD of infants around the age of one year based on their GMs recorded early in life. This study not only helps clinicians better understand infant CD mechanisms, but also provides an economical, portable and non-invasive way to screen infants at high-risk early to facilitate their recovery.

Mother-infant self- and interactive contingency at four months and infant cognition at one year: A view from microanalysis

Although a considerable literature documents associations between early mother-infant interaction and cognitive outcomes in the first years of life, few studies examine the contributions of contingently coordinated mother-infant interaction to infant cognitive development. This study examined associations between the temporal dynamics of the contingent coordination of mother-infant face-to-face interaction at 4 months and cognitive performance on the Bayley Scales of Infant Development at age one year in a sample of (N = 100) Latina mother-infant pairs. Split-screen videotaped interactions were coded on a one second time base for the communication modalities of infant and mother gaze and facial affect, infant vocal affect, and mother touch. Multi-level time-series models evaluated self- and interactive contingent processes in these modalities and revealed 4-month patterns of interaction associated with higher one-year cognitive performance, not identified in prior studies. Infant and mother self-contingency, the moment-to-moment probability that the individual’s prior behavior predicts the individual’s future behavior, was the most robust measure associated with infant cognitive performance. Self-contingency findings showed that more varying infant behavior was optimal for higher infant cognitive performance, namely, greater modulation of negative affect; more stable maternal behavior was optimal for higher infant cognitive performance, namely, greater likelihood of sustaining positive facial affect. Although interactive contingency findings were sparse, they showed that, when mothers looked away, or dampened their faces to interest or mild negative facial affect, infants with higher 12-month cognitive performance were less likely to show negative vocal affect. We suggest that infant ability to modulate negative affect, and maternal ability to sustain positive affect, may be mutually reinforcing, together creating a dyadic climate that is associated with more optimal infant cognitive development.

Developing biopolymer-stabilized emulsions for improved stability and bioaccessibility of lutein

Lutein is essential for infant visual and cognitive development but has low stability and solubility. This study aimed to enhance the stability and bioaccessibility of lutein using oil-in-water emulsions stabilized with biopolymers. Commercially available octenylsuccinylated (OS) starches, including capsule TA® (CTA), HI-CAP®100 (HC), and Purity Gum® 2000 (PG), along with gum Arabic (GA) variants Ticaloid acacia Max® (TAM), TICAmulsion® 3020 (TM), and pre-hydrate gum Arabic (PHGA), were chosen as emulsifiers. By screening the effect of biopolymer concentration and oil volume fraction (Φ), emulsions stabilized with CTA, HC, or TM at 20% and 30% (w/v) concentration and 70% Φ exhibited a gel-like structure and were selected for further assessments. After a week at 25 °C, emulsions stabilized by CTA and HC showed no significant change in droplet size, while TM emulsion exhibited a 1.58-fold increase. At 45 °C, all emulsions exhibited increase in droplet size. Lutein retention is higher in CTA emulsions at both storage temperatures than free lutein. In vitro bioaccessibility of all lutein emulsions was higher than that of free lutein. These findings highlight the superior stability and bioaccessibility of the lutein emulsion stabilized by OS starch, positioning it as a promising carrier to broaden lutein applications in infant foods.

Neurodevelopment of Attention, Learning, and Memory Systems in Infancy

Understanding how we come to make sense of our environments requires understanding both how we take in new information and how we flexibly process and store that information in memory for subsequent retrieval. In other words, infant cognitive development research is best served by studies that probe infant attention as well as infant learning and memory development. In this article, we first review what is known about infant attention and what is known about a selection of learning systems available in infancy. Then, we review what is known about the interactions between attention and these systems, focusing on infancy when possible but highlighting relevant child and adult literatures when infant research is yet scarce. Finally, we close by proposing a path forward, which we believe will result in a clearer understanding of the interactions between attention and memory that govern infant learning.

Vaccine value profile for enterotoxigenic Escherichia coli (ETEC)

Enterotoxigenic Escherichia coli (ETEC) is one of the leading bacterial causes of diarrhoea, especially among children in low-resource settings, and travellers and military personnel from high-income countries. WHO’s primary strategic goal for ETEC vaccine development is to develop a safe, effective, and affordable ETEC vaccine that reduces mortality and morbidity due to moderate-to-severe diarrhoeal disease in infants and children under 5 years of age in LMICs, as well as the long-term negative health impact on infant physical and cognitive development resulting from infection with this enteric pathogen. An effective ETEC vaccine will also likely reduce the need for antibiotic treatment and help limit the further emergence of antimicrobial resistance bacterial pathogens.The lead ETEC vaccine candidate, ETVAX, has shown field efficacy in travellers and has moved into field efficacy testing in LMIC infants and children. A Phase 3 efficacy study in LMIC infants is projected to start in 2024 and plans for a Phase 3 trial in travellers are under discussion with the U.S. FDA. Licensing for both travel and LMIC indications is projected to be feasible in the next 5–8 years.Given increasing recognition of its negative impact on child health and development in LMICs and predominance as the leading etiology of travellers’ diarrhoea (TD), a standalone vaccine for ETEC is more cost-effective than vaccines targeting other TD pathogens, and a viable commercial market also exists. In contrast, combination of an ETEC vaccine with other vaccines for childhood pathogens in LMICs would maximize protection in a more cost-effective manner than a series of stand-alone vaccines.This ‘Vaccine Value Profile’ (VVP) for ETEC is intended to provide a high-level, holistic assessment of available data to inform the potential public health, economic and societal value of pipeline vaccines and vaccine-like products. This VVP was developed by a working group of subject matter experts from academia, non-profit organizations, public private partnerships, and multi-lateral organizations. All contributors have extensive expertise on various elements of the ETEC VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using only existing and publicly available information.

Maternal childbirth-related posttraumatic stress symptoms, bonding, and infant development: a prospective study

ABSTRACT Background Childbirth-related posttraumatic stress symptoms (CB-PTSS) including general symptoms (GS, i.e., mainly negative cognitions and mood and hyperarousal symptoms) and birth-related symptoms (BRS, i.e., mostly re-experiencing and avoidance symptoms) may disrupt mother-infant bonding and infant development. This study investigated prospective and cross-sectional associations between maternal CB-PTSS and mother-infant bonding or infant development (language, motor, and cognitive). Method We analysed secondary data of the control group of a randomised control trial (NCT 03576586) with full-term French-speaking mother-infant dyads (n = 55). Maternal CB-PTSS and mother-infant bonding were assessed via questionnaires at six weeks (T1) and six months (T2) postpartum: PTSD Checklist for DSM-5 (PCL-5) and Mother-Infant Bonding Scale (MIBS). Infant development was assessed with the Bayley Scales of Infant Development at T2. Sociodemographic and medical data were collected from questionnaires and medical records. Bivariate and multivariate regression were used. Results Maternal total CB-PTSS score at T1 was associated with poorer bonding at T2 in the unadjusted model (B = 0.064, p = 0.043). In the adjusted model, cross-sectional associations were found at T1 between a higher total CB-PTSS score and poorer bonding (B = 0.134, p = 0.017) and between higher GS and poorer bonding (B = 0.306, p = 0.002). Higher BRS at T1 was associated with better infant cognitive development at T2 in the unadjusted model (B = 0.748, p = 0.026). Conclusions Results suggest that CB-PTSS were associated with mother-infant bonding difficulties, while CB-PTSS were not significantly associated with infant development. Additional studies are needed to increase our understanding of the intergenerational consequences of perinatal trauma.

Mother-infant interaction and infant development in women at risk of postpartum psychosis with and without a postpartum relapse.

This study aimed to investigate mother-infant interaction and infant development in women at-risk of postpartum psychosis (PP), with and without a postpartum relapse. 103 women (and their offspring) were included, 43 at-risk-of-PP because of a diagnosis of bipolar disorder, schizoaffective disorder or previous PP, and 60 with no current/previous mental illness or family history of PP. Of the at-risk women, 18 developed a psychiatric relapse within 4 weeks after delivery (AR-unwell), while 25 remained symptom-free (AR-well). Mother-infant interaction was assessed using the CARE-Index at 8 weeks' and 12 months' postpartum and infant development using the Bayley-III at 12 months' postpartum. Women at-risk-of-PP as a group, regardless of whether they developed a psychiatric relapse within 4 weeks after delivery, had less synchronous mother-infant interactions and had infants with less optimal cognitive, language, motor and socio-emotional development than healthy controls. In particular, boys of at-risk women had the lowest scores in cognitive, language and motor development and in mother-infant interaction, while girls of the at-risk women had the lowest scores in socio-emotional development. The synchrony in the dyad predicted infant cognitive and language development. There was no evidence for a difference in mother-infant interaction nor in infant development between the AR-unwell and AR-well groups. These results suggest that, while there is a lack of evidence that an early postpartum relapse in women at-risk-of-PP could represent a risk for the infant per se, maternal risk for PP may be associated with less optimal mother-infant interaction and infant development.

A study protocol in assessing knowledge attitude practices of breastfeeding amongst lactating women in Wardha, Maharashtra

Background: The best strategy for enhancing a child's health is breastfeeding. Success depends on starting breastfeeding as soon as possible after birth. Breastfeeding should begin during the first few hours of life and should be continued for the first six months, according to the World Health Organization (WHO) and UNICEF. Early initiation of breastfeeding and six months of exclusive nursing are necessary for the infant's cognitive development. For a child to meet their developmental milestones and reduce the incidence of infant mortality in India, nutrition throughout the first 1000 days of life is essential. A substantial focus on modifying feeding habits in the first 1000 days is required. The study’s objectives are to assess the knowledge regarding early initiation to exclusive breastfeeding after childbirth (within 24 hours and seven days of post-delivery) and the knowledge regarding breastfeeding techniques. Methods: In this cross-sectional study, 355 lactating women are included in the age group of 20-35 years in the Wardha district. The study excludes those women who are not willing to participate, and those with medical conditions such as HIV, cancer, psychosis, active tuberculosis, complicated delivery, the baby who required neonatal NICU and neonatal resuscitation admission in the immediate post-delivery period, and those with Gross Congenital anomaly. The key outcome variables were timely and exclusive breastfeeding initiation and techniques. The data collection tool is a face-to-face questionnaire that will be developed through open data kit (ODK)) based on WHO and NFHS-4 and 5 surveys. We will analyze data through the use of Microsoft Excel software. Conclusions: Early breastfeeding initiation, exclusive breastfeeding, and supplemental feeding strategies are all included in the research to assess and identify women's knowledge, attitude, and nursing practices.

Frequency of Postpartum Depression (PPD) in Rawalpindi and its determinants

Background: Postpartum Depression (PPD) is a common complication after childbirth. It has serious impact on mental health of mother as well as behavioral and cognitive development of infant. Objective: To determine frequency of PPD in a metropolitan area of Pakistan and its associated factors. Methods: A cross sectional study was conducted at Gynecology and Obstetrics Department of Fauji Foundation Hospital, Rawalpindi over a period of six months from January to June 2022. A total of 252 female patients fulfilling the inclusion criteria were included. Patients Health Questionnaire (PHQ 9) was used for screening of PPD in the test subjects. Patients were categorized into two major groups: PPD (PHQ 9 ≥ 5) and No PPD (PHQ 9 ≤ 4). Odds ratio (OR) with 95% confidence interval was used to determine the association of various factors with PPD. Results: Out of 252 patients, 87 (34.5%) had PPD while 165 (65.5%) had no PPD. The major determinants were Age > 35 years (OR 5.00, CI 1.286-19.440), BMI > 30 (OR 3.333, CI 0.77-14.43), Gestational Age ≤35 weeks (OR 6.354, CI 2.65-10.678), Parity >4 (OR 2.364, CI 0.548-10.19), number of female children >4 (OR 7.670, CI 3.458-9.650), Low birth weight baby (OR 2.529, CI 1.109-5.766), COVID-19 in pregnancy (OR 2.371, CI 1.162-4.838), family history of depression (OR 4.425, CI 2.119-9.242), past history of PPD (OR 3.793, CI 1.780-8.085), no social support from husband (OR 11.379, CI 3.447-37.5) and family (OR 6.322, CI 3.145- 12.707). Conclusion: The major determinants of PPD in this study were lack of social support from husband and family members, previous female children and preterm deliveries. Other risk factors included age, obesity, multiparity, low birth weight, COVID-19 in pregnancy, family history of depression and stressful event during pregnancy, sleep deprivation, bottle feeding practice, and neonatal admission in NICU.

Comparison of phospholipid composition and microstructure of milk fat globules contained in human milk and infant formulae.

Phospholipids play key roles in infant nutrition and cognitive development. It is hypothesized that infant formula (IF) has lower phospholipid species, content and milk fat globule (MFG) structural integrity than human milk (HM). Herein, we performed qualitative and quantitative analyses of phospholipids in six classes of IF and HM using ultra-performance liquid chromatography with mass spectrometry. The contents of phosphatidylethanolamine (15.81±7.20mg/L) and sphingomyelin (35.84±15.56mg/L) in IF were significantly lower than those in HM (30.74±17.38mg/L, 45.53±16.04mg/L, respectively). Among the six IF classes, cow's milk-based IF had the highest number of phospholipid species, and IF containing milk fat globular membrane had the highest phospholipid content. The size, zeta potential, and amount of MFGs in IF were significantly lower than those in HM. These results may prove useful for designing better IF that mimic HM.

Interactions between Bifidobacterium and Bacteroides and human milk oligosaccharides and their associations with infant cognition.

While ample research on independent associations between infant cognition and gut microbiota composition and human milk (HM) oligosaccharides (HMOs) has been reported, studies on how the interactions between gut microbiota and HMOs may yield associations with cognitive development in infancy are lacking. We aimed to determine how HMOs and species of Bacteroides and Bifidobacterium genera interact with each other and their associations with cognitive development in typically developing infants. A total of 105 mother-infant dyads were included in this study. The enrolled infants [2.9-12 months old (8.09 ± 2.48)] were at least predominantly breastfed at 4 months old. A total of 170 HM samples from the mothers and fecal samples of the children were collected longitudinally. Using the Mullen Scales of Early Learning to assess cognition and the scores as the outcomes, linear mixed effects models including both the levels of eight HMOs and relative abundance of Bacteroides and Bifidobacterium species as main associations and their interactions were employed with adjusting covariates; infant sex, delivery mode, maternal education, site, and batch effects of HMOs. Additionally, regression models stratifying infants based on the A-tetrasaccharide (A-tetra) status of the HM they received were also employed to determine if the associations depend on the A-tetra status. With Bacteroides species, we observed significant associations with motor functions, while Bif. catenulatum showed a negative association with visual reception in the detectable A-tetra group both as main effect (value of p = 0.012) and in interaction with LNFP-I (value of p = 0.007). Additionally, 3-FL showed a positive association with gross motor (p = 0.027) and visual reception (p = 0.041). Furthermore, significant associations were observed with the interaction terms mainly in the undetectable A-tetra group. Specifically, we observed negative associations for Bifidobacterium species and LNT [breve (p = 0.011) and longum (p = 0.022)], and positive associations for expressive language with 3'-SL and Bif. bifidum (p = 0.01), 6'-SL and B. fragilis (p = 0.019), and LNFP-I and Bif. kashiwanohense (p = 0.048), respectively. Our findings suggest that gut microbiota and HMOs are both independently and interactively associated with early cognitive development. In particular, the diverse interactions between HMOs and Bacteroides and Bifidobacterium species reveal different candidate pathways through which HMOs, Bifidobacterium and Bacteroides species potentially interact to impact cognitive development in infancy.

Exploring key cognitive indicators for practical use by parents in community setting

The identification of child development milestones, specifically cognitive abilities, requires parental/caregiver awareness and knowledge. With the existence of multiple cognitive abilities such as attention and focus, memory, language, psychomotor skills, logic, reasoning, decision-making, problem-solving, social/emotional, there are multiple indicators to measure children's cognitive abilities. Pediatricians are the most knowledgeable and trusted authority to routinely screen and monitor the development of healthy children. Therefore, it is crucial that parents understand their children's developmental milestones so if they encounter anomalies, they can immediately consult with the professionals. This review compiles recently published research and current knowledge to examine potential key indicators of cognitive development in infants and children that can be utilized by parents and communities in an easily understood manner.

Verbal Behavior of Mothers With Opioid Use Disorder While Feeding Infants With Neonatal Opioid Withdrawal Syndrome.

An infant's cognitive development is highly dependent on early interactions with its primary caregiver, often its mother. Feeding, a frequent and early exchange between mothers and infants, is an important time for maternal-infant bonding. Mothers with opioid use disorder have been found to be more physically and verbally stimulating and more active during feeds than mothers with no opioid use. The purpose of this study was to describe the characteristics of verbal interactions mothers with opioid use disorder expressed while engaged in a feeding encounter with their infant undergoing treatment for neonatal opioid withdrawal syndrome to offer insight into maternal experiences and potential challenges of feeding infants experiencing withdrawal. A qualitative descriptive analysis of maternal verbalizations during the feeding was used in a secondary analysis using the Barnard Model as the theoretical framework for maternal-infant interaction. A theory-driven deductive approach was assumed to organize the identified subthemes within the concepts of the Barnard Model. Mothers frequently commented on hunger, satiation, and stress cues, while providing consolation, praise, and encouragement. Mothers expressed concerns regarding feeding volume and pace, and consequences related to feeding. It is crucial that clinicians remember that feeding is an important time for maternal-infant bonding. Further research into the feeding interactions of mother-infant dyads with opioid exposure is warranted. As infants may present with subacute signs of withdrawal, including persistent feeding difficulties for months, further investigation into feeding challenges dyads experience after discharge from the hospital is needed.

Maternal physiological calming responses to infant suckling at the breast

The mother–infant relation is key to infant physical, cognitive and social development. Mutual regulation and cooperation are required to maintain the dyadic system, but the biological foundation of these responses remains to be clarified. In this study, we report the maternal calming responses to infant suckling during breastfeeding. Using behavioral measures and a Holter electrocardiogram as a readout of the maternal autonomic nervous system, the maternal activities during resting, sitting with her infant on her lap, and breastfeeding were assessed. We found that during breastfeeding, mothers talked less and maternal heart rate was lower than during sitting with the infant without breastfeeding. Congruently, maternal heart rate variability measurements indicated a higher parasympathetic activity during breastfeeding. Time-locked analyses suggested that this maternal calming response was initiated by the tactile stimulation at the breast by the infant face or mouth latch, which preceded the perceived milk ejection. These findings suggest that somatosensory stimuli of breastfeeding activate parasympathetic activity in mothers. Just as how the infant Transport Response facilitates the carrying of infants, the maternal calming responses during breastfeeding may promote efficient milk intake by inhibiting spontaneous maternal activities.

Preterm Birth and Other Measures of Infant Biological Vulnerability: Associations with Maternal Sensitivity and Infant Cognitive Development.

Low birth weight (LBW), biological vulnerability that includes preterm birth (PTB) and small for gestational age (SGA), is associated with reduced maternal sensitivity ("making accurate inferences about an infant's physical and emotional needs and responding appropriately") and impaired infant cognitive development. However, research does not examine if preterm birth, SGA, or both drive these associations. This study separated these measures of biological vulnerability to examine associations of LBW, PTB, and SGA with maternal sensitivity and infant cognitive development (controlling for maternal depression, breastfeeding, and demographic covariates). The sample included 6900 9-month-old infants from the Early Childhood Longitudinal Study-Birth Cohort and used birth certificate data, maternal interviews, assessments of maternal sensitivity and infant cognitive development. Multiple linear regressions examined LBW, PTB, and SGA associations with concurrent measures of maternal sensitivity and infant cognition. Of the biological vulnerabilities, preterm birth had the strongest negative association with maternal sensitivity (F1,6450 = 29.48 versus 15.33 and 5.51,ps < .001) and infant cognitive development (F1,6450) = 390.65 versus 248.02 and 14.43,ps < .001). In the final regression model, preterm birth and maternal sensitivity were uniquely associated with infant cognitive development (R2 = .05, p < .001), after controlling for maternal depression, breastfeeding, and demographics. In this nationally representative infant sample infants, PTB had a stronger negative association with both maternal sensitivity and infant cognitive development in comparison to SGA or LBW. The LBW designation combines infants born preterm with SGA infants, potentially minimizing differences in developmental outcomes of PTB and SGA infants.

A Narrative Review on the Effect of Maternal Hypothyroidism on Fetal Development.

The thyroid is a butterfly-shaped gland located in the human body's neck region. The thyroid produces three hormones that are essential for regulating body temperature, energy production, weight, hair and nail growth, and menstrual cycle maintenance. The production of these hormones is controlled by a feedback mechanism. Various factors cause changes in the stimulation and inhibition of these hormones, which ultimately causes either excessive release or a decrease in the levels of thyroid hormones. These causes can be physiological or pathological. One of the physiological causes is pregnancy. Pregnancy is a very complex process in whichmany changes occur in the body and its functioning. One of which is changes in the maternal thyroid gland. The inability to adequately adapt to the changes leads to the abnormal functioning of the thyroid gland. During pregnancy, there is a variation in the concentration of thyroid hormones which may cause a decrease in levels or inhibition in the production of thyroid hormones. This condition is called hypothyroidism. Hypothyroidism in pregnant mothers can either be gestational or may be a condition that is present way before her pregnancy. Often, gestational hypothyroidism reverts after delivery during the postpartum period but can also be present as subclinical hypothyroidism. In such cases, they pose a significant threat to development, cause growth hindrance to the infant in the womb, and cause abnormalities in the offspringin the future. Some of the changes occur in the gland because of enhancement in levels of thyroid binding globulin, increased clearance rate of iodine from the body in kidneys, altered effects in human chorionic gonadotropin hormone, and decreased consumption of iodine in meals. Iodine disbalance in maternal hypothyroidism is associated with severe health issues like cretinism and mental retardation. Thyroid hormones are crucial for the infant's neural, cognitive, and intelligence quotient development in the womb. Thus, the disturbances in the maternal hormone levels disturb typical early developmental characteristics. In the world of rapidly advancing scientific research, there are many ways in which this condition can be detected early, diagnosed correctly, and given apt and required attention and treatment for causing the least harm to the fetus and the mother.

Six facial prosodic expressions caregivers similarly display to infants and dogs

Parents tend to use a specific communication style, including specific facial expressions, when speaking to their preverbal infants which has important implications for children’s healthy development. In the present study, we investigated these facial prosodic features of caregivers with a novel method that compares infant-, dog- and adult-directed communication. We identified three novel facial displays in addition to the already described three facial expressions (i.e. the ‘prosodic faces’) that mothers and fathers are typically displaying when interacting with their 1–18 month-old infants and family dogs, but not when interacting with another adult. The so-called Special Happy expression proved to be the most frequent face type during infant- and dog-directed communication which always includes a Duchenne marker to convey an honest and intense happy emotion of the speaker. These results suggest that the ‘prosodic faces’ play an important role in both adult-infant and human–dog interactions and fulfil specific functions: to call and maintain the partner’s attention, to foster emotionally positive interactions, and to strengthen social bonds. Our study highlights the relevance of future comparative studies on facial prosody and its potential contribution to healthy emotional and cognitive development of infants.

Insidensi Bayi Berat Lahir Rendah pada Spektrum Plasenta Akreta di Rumah Sakit Dr Hasan Sadikin Bandung

Low birth weight (LBW) babies are closely related to infant morbidity, stunted growth and cognitive development, and chronic diseases. Placenta accreta spectrum (PAS) is a condition that complicates pregnancy and is closely related to low birth weight. Objectives: To determined the incidence of LBW in mothers with SPA at the hospital Dr. Hasan Sadikin Bandung. Methods: A descriptive observational study involving 71 cases of SPA in hospitals Dr. Hasan Sadikin Bandung, period 2016-2020, which has met the inclusion and exclusion criteria. SPA cases were divided into three groups: placenta accreta, increta, and percreta. In each SPA group, the incidence of LBW was evaluated. Results: 46.5% (33/71 cases of PAS) had low birth weight, while 53.5% (38/71 cases of PAS) had normal birth weight babies. The placenta accreta and percreta groups were dominated by normal birth weight infants [(18/31 cases), (5/9 cases)], while the placenta increta group was dominated by low birth weight infants (16/31 cases). The LBW category is divided into Extremely Low Birth Weight (ELBW), Very Low Birth Weight (VLBW), and LBW. In placenta accreta, there were 2 ELBW and VLBW infants, and 9 LBW infants. In the placenta increta, there are 3 ELBW and VLBW, and 10 LBW. In the placenta percreta, there were 1 ELBW and 3 LBW, while VLBW was not found in the placenta percreta. Conclusion: The incidence of LBW is found in almost half the population of SPA cases in hospitals. DR. Hasan Sadikin in the 2016-2020 period.Keywords: low birth weight, placenta accreta spectrum

Beyond Infant’s Looking: The Neural Basis for Infant Prediction Errors

Contemporary conceptualizations on infant cognitive development focus on predictive processes; the basic idea is that the brain continuously creates predictions about what is expected and that the divergence between predicted and actual perceived data yields a prediction error. This prediction error updates the model from which the predictions are generated and therefore is a basic mechanism for learning and adaptation to the dynamics of the ever-changing environment. In this article, we review the types of available empirical evidence supporting the idea that predictive processes can be found in infancy, especially emphasizing the contribution of electrophysiology as a potential method for testing the similarity of the brain mechanisms for processing prediction errors in infants to those of adults. In infants, as with older children, adolescents, and adults, predictions involve synchronization bursts of middle-central theta reflecting brain activity in the anterior cingulate cortex. We discuss how early in development such brain mechanisms develop and open questions that still remain to be empirically investigated.
