Examining the Relation Between Prenatal Emotion Dysregulation and Toddler Vocabulary Development: A Biobehavioral Approach.

Early language is shaped by parent-child interactions and has been examined in relation to maternal psychopathology and parenting stress. Minimal work has examined the relation between maternal emotion dysregulation and toddler vocabulary development. This longitudinal study examined associations between maternal emotion dysregulation prenatally, maternal everyday stress at 7 months postpartum, and toddler vocabulary at 18 months.

From prenatal maternal anxiety and respiratory sinus arrhythmia to toddler internalizing problems: The role of infant negative affectivity.

Prenatal maternal anxiety is considered a risk factor for the development of child internalizing problems. However, little is known about potential mechanisms that account for these associations. The current study examined whether prenatal maternal anxiety was indirectly associated with toddler internalizing problems via prenatal maternal physiology and infant negative affectivity.

A bioecological longitudinal study of depressive symptoms from pregnancy to 36 months postpartum.

Purpose: Depressive symptoms during the perinatal period have broad and enduring health implications for birthing parents and their offspring. Rising prevalence rates of perinatal depression highlight the need for research examining factors influencing depressive symptoms during pregnancy, and trajectories during the early postnatal period. Grounded in bioecological systems theory, this longitudinal multimethod study examined whether prenatal bioecological factors predict depressive symptoms from pregnancy to 36 months postpartum.

Examining the implications of contextual stress and maternal sensitivity for infants' cortisol responses to the still face paradigm.

Infants' hypothalamic-pituitary-adrenocortical (HPA) axis responses to acute stressors are theorized to be shaped by parents' sensitive responsiveness to infants' cues. The strength and direction of the association between maternal sensitivity and infants' HPA responses may depend on the context in which maternal sensitivity is observed and on broader environmental sources of stress and support. In this preregistered study, we used data from 105 mothers and their 7-month-old infants to examine whether two empirically identified forms of contextual stress-poor maternal psychosocial wellbeing and family socioeconomic hardship-moderate the association between maternal sensitivity and infants' cortisol responses to the Still-Face Paradigm (SFP).

Understanding emotion dysregulation from infancy to toddlerhood with a multilevel perspective: The buffering effect of maternal sensitivity.

Challenges with childhood emotion regulation may have origins in infancy and forecast later social and cognitive developmental delays, academic difficulties, and psychopathology. This study tested whether markers of emotion dysregulation in infancy predict emotion dysregulation in toddlerhood, and whether those associations depended on maternal sensitivity. When children ( = 111) were 7 months, baseline respiratory sinus arrhythmia (RSA), RSA withdrawal, and distress were collected during the Still Face Paradigm (SFP).

Insights into child abuse and neglect: Findings from the Minnesota Longitudinal Study of Risk and Adaptation.

The Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) is a landmark prospective, longitudinal study of human development focused on a sample of mothers experiencing poverty and their firstborn children. Although the MLSRA pioneered a number of important topics in the area of social and emotional development, it began with the more specific goal of examining the antecedents of child maltreatment. From that foundation and for more than 40 years, the study has produced a significant body of research on the origins, sequelae, and measurement of childhood abuse and neglect.

The Combined Contributions of Newborn Stress and Parenting Stress on Toddler Language Development.

Objective: To examine the longitudinal associations between newborn neurobehavioral stress signs, maternal parenting stress, and several indices of toddler language development.

Study Design: Participants include 202 mother-infant dyads (104 girls). We measured stress signs in neonates in the hospital at least 24 hours after birth using the Neonatal Intensive Care Unit Network Neurobehavioral Scale.

The unanticipated side effects of an attachment intervention: Parents ask higher quality questions.

Research suggests foster children are at risk for poor language skills. One intervention, attachment and biobehavioral catch-up (ABC), was shown to successfully improve not only young foster children's attachment to their parents, but also their receptive vocabulary skills (Bernard et al., 2017; Raby et al.

The predictive validity of the strange situation procedure: Evidence from registered analyses of two landmark longitudinal studies.

Meta-analyses demonstrate that the quality of early attachment is modestly associated with peer social competence ( = .19) and externalizing behavior ( = -.15), but weakly associated with internalizing symptoms ( = -.

Pregnant women's autonomic responses to an infant cry predict young infants' behavioral avoidance during the still-face paradigm.

Research suggests that women's autonomic nervous system responses to infant cries capture processes that affect their parenting behaviors. The aim of this study was to build on prior work by testing whether pregnant women's autonomic responses to an unfamiliar infant crying also predict their infants' emerging regulation abilities. Participants included 97 women in their third trimester of pregnancy, located in the United States.

Is Attachment and Biobehavioral Catch-up effective for parents with insecure attachment states of mind?

Prior research suggests that attachment-based interventions, including Attachment and Biobehavioral Catch-up (ABC), may be less effective at enhancing parenting quality among parents who self-report having an insecure attachment style. The current study tested whether effects of ABC on parental behavior were moderated by categorical and dimensional measures of attachment obtained via Adult Attachment Interviews with 454 parents who were approximately 34 years old, primarily female, and predominantly White or African American. Parents randomized to ABC exhibited higher sensitivity and positive regard, and lower intrusiveness shortly after the intervention than parents randomized to the control intervention (|β|s = .

Mechanisms of airway epithelial injury and abnormal repair in asthma and COPD.

The airway epithelium comprises of different cell types and acts as a physical barrier preventing pathogens, including inhaled particles and microbes, from entering the lungs. Goblet cells and submucosal glands produce mucus that traps pathogens, which are expelled from the respiratory tract by ciliated cells. Basal cells act as progenitor cells, differentiating into different epithelial cell types, to maintain homeostasis following injury.

Examining implications of the developmental timing of maternal trauma for prenatal and newborn outcomes.

Separate literatures have demonstrated that mothers' experiences with trauma during childhood or pregnancy are associated with maternal prenatal health risks, adverse childbirth outcomes, and offspring internalizing and externalizing disorders. These literatures largely align with the intergenerational transmission or fetal programming frameworks, respectively. However, few studies have tested the effects of maternal childhood and prenatal trauma simultaneously on mothers' and infants' health outcomes, and no studies have examined these effects on newborn neurobehavioral outcomes.

Precision Medicine Intervention in Severe Asthma (PRISM) study: molecular phenotyping of patients with severe asthma and response to biologics.

Severe asthma represents an important clinical unmet need despite the introduction of biologic agents. Although advanced omics technologies have aided researchers in identifying clinically relevant molecular pathways, there is a lack of an integrated omics approach in severe asthma particularly in terms of its evolution over time. The collaborative Korea-UK research project Precision Medicine Intervention in Severe Asthma (PRISM) was launched in 2020 with the aim of identifying molecular phenotypes of severe asthma by analysing multi-omics data encompassing genomics, epigenomics, transcriptomics, proteomics, metagenomics and metabolomics.

Dynamics of mother-infant parasympathetic regulation during face-to-face interaction: The role of maternal emotion dysregulation.

The dynamics of parent-infant physiology are essential for understanding how biological substrates of emotion regulation are organized during infancy. Although parent-infant physiological processes are dyadic in nature, research is limited in understanding how one person's physiological responses predict one's own and as well as the other person's responses in the subsequent moment. In this study, we examined mother-infant respiratory sinus arrhythmia (RSA) dynamics during the Still-Face Paradigm (SFP) among 106 mothers (M  = 29.

Predictors of heart failure and all-cause mortality in asymptomatic patients with moderate and severe aortic regurgitation.

Background: Class I indications for aortic valve replacement (AVR) for severe chronic aortic regurgitation (AR) include AR attributable symptoms or left ventricular (LV) ejection fraction <50%. As noninvasive estimates of elevated LV filling pressures (LVFP's) have been noted to predict heart failure (HF) readmission and all-cause mortality (ACM) in HF patients, we hypothesize that elevated LVFP's may also be independent predictors of HF and ACM in chronic AR.

Methods: We developed a single center patient database of moderate or greater AR diagnoses between 2003 and 2008 and followed each patient through January 2013.

Developmental foundations of physiological dynamics among mother-infant dyads: The role of newborn neurobehavior.

This study tested whether newborn attention and arousal provide a foundation for the dynamics of respiratory sinus arrhythmia (RSA) in mother-infant dyads. Participants were 106 mothers (M  = 29.54) and their 7-month-old infants (55 males and 58 White and non-Hispanic).

Exploring the meaning of unresolved loss and trauma in more than 1,000 Adult Attachment Interviews.

Unresolved states of mind regarding experiences of loss/abuse (U/d) are identified through lapses in the monitoring of reasoning, discourse, and behavior surrounding loss/abuse in response to the Adult Attachment Interview. Although the coding system for U/d has been widely used for decades, the individual indicators of unresolved loss/abuse have not been validated independently of the development sample. This study examined the psychometric validity of U/d, using individual participant data from 1,009 parent-child dyads across 13 studies.

Unique Contributions of Maternal Prenatal and Postnatal Emotion Dysregulation on Infant Respiratory Sinus Arrhythmia.

Prenatal intrauterine exposures and postnatal caregiving environments may both shape the development of infant parasympathetic nervous system (PNS) activity. However, the relative contributions of prenatal and postnatal influences on infant respiratory sinus arrhythmia (RSA)-an index of PNS functioning-are relatively unknown. We examined whether prenatal and postnatal maternal emotion dysregulation, a transdiagnostic construct that spans mental health diagnoses, were independently related to infant RSA trajectories during a social stressor, the still-face paradigm.

Adapting psychophysiological data collection for COVID-19: The "Virtual Assessment" model.

The COVID-19 pandemic has significantly disrupted research activities globally. Researchers need safe and creative procedures to resume data collection, particularly for projects evaluating infant mental health interventions. Remote research is uniquely challenging for psychophysiological data collection, which typically requires close contact between researchers and participants as well as technical equipment frequently located in laboratory settings.

Bringing the laboratory into the home: A protocol for remote biobehavioral data collection in pregnant women with emotion dysregulation and their infants.

Pregnant women struggling with emotion dysregulation may be more likely to engage in a wide range of health risk behaviors. This protocol describes a study on intergenerational transmission of emotion dysregulation from the third trimester of pregnancy to 18 months postpartum. Biobehavioral markers of emotion dysregulation are typically measured in laboratory settings which was prohibited by many universities during the COVID-19 pandemic.

Molecular mechanisms of oxidative stress in asthma.

The lungs are exposed to reactive oxygen species oxygen (ROS) produced as a result of inhalation of oxygen, as well as smoke and other air pollutants. Cell metabolism and the NADPH oxidases (Nox) generate low levels of intracellular ROS that act as signal transduction mediators by inducing oxidative modifications of histones, enzymes and transcription factors. Redox signalling is also regulated by localised production and sensing of ROS in mitochondria, the endoplasmic reticulum (ER) and inside the nucleus.

Adverse Outcomes with Eccentric Hypertrophy in a Community Based University Cohort with Aortic Stenosis.

Objective: Aortic stenosis (AS) patients with eccentric hypertrophy (Ecc-LVH) have increased left ventricular (LV) size and possibly reduced ejection fraction (EF). However, previous studies suggest worse outcomes with concentric remodeling and hypertrophy. We hypothesized that Ecc-LVH pattern in AS patients will also be associated with greater heart failure (HF) and all-cause mortality (ACM).
