Maternal parenting stress changes over the first year of life in infants with complex cardiac defects and in healthy infants

Objectives: Parents of infants with CHDs experience increased parenting stress compared to the general population, potentially interfering with parenting practices and bear adverse family outcomes. The changes in stress over the critical period of infancy have yet to be studied. The current study aimed to compare parenting stress changes over time between parents of infants with CHDs and parents of healthy infants during the first year of infants’ life. Methods: Data from a larger prospective cohort study were longitudinally analysed using mixed-effects multivariable regression modelling. Sample included mothers of 129 infants with complex cardiac defects and healthy infants, recruited from the cardiac ICU of a large cardiac centre and outpatient paediatric practices in Northeastern America. Outcome was measured over four visits via the Parenting Stress Index Long Form. Results: Stress in the cardiac group has significantly decreased over time on the Parent Domain (p = 0.025), and stress in the healthy group has significantly increased over time on the Child Domain (p = 0.033). Parenting stress trajectories demonstrated significant differences between groups on the Parent Domain (p = 0.026) and on the Total Stress (p = 0.039) subscales. Conclusions: Parenting stress in the paediatric cardiac population changes over time and differs from stress experienced by parents of healthy infants. Findings highlight stressful periods that may be potentially risky for parents of infants with CHDs and introduce additional illness-related and psychosocial/familial aspects to the parenting stress concept.

A nested multi-scale system implemented in the large-eddy simulation model PALM model system 6.0

Large-eddy simulation (LES) provides a physically sound approach to study complex turbulent processes within the atmospheric boundary layer including urban boundary layer flows. However, such flow problems often involve a large separation of turbulent scales, requiring a large computational domain and very high grid resolution near the surface features, leading to prohibitive computational costs. To overcome this problem, an online LES–LES nesting scheme is implemented into the PALM model system 6.0. The hereby documented and evaluated nesting method is capable of supporting multiple child domains, which can be nested within their parent domain either in a parallel or recursively cascading configuration. The nesting system is evaluated by first simulating a purely convective boundary layer flow system and then three different neutrally stratified flow scenarios with increasing order of topographic complexity. The results of the nested runs are compared with corresponding non-nested high- and low-resolution results. The results reveal that the solution accuracy within the high-resolution nest domain is clearly improved as the solutions approach the non-nested high-resolution reference results. In obstacle-resolving LES, the two-way coupling becomes problematic as anterpolation introduces a regional discrepancy within the obstacle canopy of the parent domain. This is remedied by introducing canopy-restricted anterpolation where the operation is only performed above the obstacle canopy. The test simulations make evident that this approach is the most suitable coupling strategy for obstacle-resolving LES. The performed simulations testify that nesting can reduce the CPU time up to 80 % compared to the fine-resolution reference runs, while the computational overhead from the nesting operations remained below 16 % for the two-way coupling approach and significantly less for the one-way alternative.

Social support as a factor of parenting stress for mothers of young and preschool children

The article is devoted to the study of the characteristics of parenting stress of mothers of young and preschool children and their relation with the relationship with the spouse and social support. The study involved 91 mothers of young and preschool children. Methods include Parenting Stress Index by Richard R. Abidin, Marriage Satisfaction Questionnaire by Yuliya Alyoshina, Social support questionnaire (F-SOZU-22), Social support questionnaire (ISEL), socio-biographical questionnaire. The study found above average level of parenting stress, average level of social support and marriage satisfaction. A close relationship was found between the characteristics of parenting stress and the characteristics of relationships with a partner (with the emotional climate in the family, marriage satisfaction, help in raising a child, time spent by a spouse with a child). Relationship with a partner is most closely associated with indicators of health and depression. Parenting stress is also closely related to the level of general social support. The most significant predictor of the level of parenting stress in mothers is among the characteristics of social support, satisfaction with social support. The strongest links between spouse relationship and social support are found with parenting stress in parent domain.

Understanding the response of tropical cyclone structure to the assimilation of synthetic wind profiles

This study examines how varying wind profile coverages in the tropical cyclone (TC) core, near-environment and broader synoptic environment affect the structure and evolution of a simulated Atlantic hurricane through data assimilation. Three sets of observing system simulation experiments (OSSEs) are examined in this paper. The first experiment establishes a benchmark for the case study specific to the forecast system used by assimilating idealized profiles throughout the parent domain. The second presents how TC analyses and forecasts respond to varying the coverage of swaths produced by polar-orbiting satellites of idealized wind profiles. The final experiment assesses the role of TC inner-core observations by systematically removing them radially from the center. All observations are simulated from a high-resolution regional “Nature Run” of a hurricane and the tropical atmosphere, assimilated an Ensemble Square-Root Kalman Filter and the Hurricane Weather and Research Forecast (HWRF) regional model. Results compare observation impact to the analyses, domain-wide and TC centric error statistics, and TC structural differences among the experiments. The study concludes that the most accurate TC representation is a result of the assimilation of collocated and uniform thermodynamic and kinematics observations. Intensity forecasts are improved with increased inner core wind observations, even if the observations are only available once daily. Domain-wide root-mean-square errors are significantly reduced when the TC is observed during a period of structural change, like rapid intensification. The experiments suggest the importance of wind observations and the role of inner-core surveillance when analyzing and forecasting realistic TC structure.

A Longitudinal Assessment of Parenting Stress in Parents of Children with New-Onset Epilepsy

Objective Parents of children with newly diagnosed epilepsy may experience elevated parenting stress. The present study examined trajectories of parenting stress over time and identified modifiable predictors of these trajectories. Methods Parents of youth with epilepsy (N = 102; 2–12 years old) completed questionnaires 1, 4, 13, 19, and 25-months post-diagnosis, including measures of parenting stress, family functioning, child psychosocial functioning, sociodemographics, and perceived stigma. Latent growth curve models (LGCM) were used to examine domains of parenting stress over time. Results At baseline, 25–48% of parents reported elevated parenting stress. LGCMs revealed that the parent and child domains of parenting stress were generally stable across time. However, life stress was more variable across time, and parents with higher initial life stress had a greater reduction in life stress over time. Socioeconomic status was identified as a non-modifiable predictor of life stress. Family functioning was associated with greater parenting stress in the parent domain. Child psychosocial functioning was associated with greater parenting stress in the parent and child domains. Conclusions Parenting stress was elevated for a subset of families and appeared to be relatively stable over time, with the exception of life stress, which was more variable. With early screening, child factors and parent appraisals of epilepsy may be valuable targets for clinical intervention with families of children with epilepsy.

Stress and the Home Environment in Caregivers of Children with Sickle Cell

Objective Caregivers of young children with chronic illnesses are at high risk for elevated levels of stress and mental health symptoms. This study examined stress and mental health symptoms as well as the socioeconomic status (SES) and home environments of a cohort of caregivers of infants and toddlers with sickle cell disease (SCD). Methods Forty-two caregivers of infants and toddlers (aged 1–34 months) with SCD completed the Brief Symptom Inventory (BSI) and Parent Stress Index (PSI). The Home Observation for Measurement of the Environment (HOME) was used to assess family living environments. Results Compared to test norms, caregivers reported high levels of situational/demographic life stress [mean difference (MD) 5.7, p = .003] and child distractibility/hyperactivity (MD 3.62, p = .001) on the PSI. However, no significant differences in psychological symptoms of distress were noted on the BSI. Caregivers scored significantly lower than norms on PSI subdomains of acceptability (MD −1.88, p = .03), competence (MD −3.11, p = .002), depression (MD −3.94, p < .001), and the overall parent domain (MD −12.55, p = .005). Significant correlations were found between PSI scores and the HOME and between SES and the HOME. Conclusion Caregivers of infants and toddlers with SCD experience elevated levels of life stress but, in turn, endorse high acceptance of their child and self-competence in parenting. Although life stress may be high in this population, symptoms of psychological distress were not identified. Caregivers reporting elevated life and illness-specific stressors may benefit from environmental supports and interventions.

SPECIFIC FEATURES OF THE PROGNOSTIC ABILITY OF PRESCHOOL CHILDREN WITH HEARING IMPAIRMENT

Background. This article considers the prediction ability (anticipation of future events) in preschool children with hearing impairment. The ability to anticipate the results of their interaction with the surrounding social world is by no means unimportant in the social adaptation of children with hearing impairment. Prediction in preschool children with hearing impairment is a rather poorly studied topic. There are studies about particular types of anticipation, such as emotional anticipation. Based on analysis of previous studies, a detailed study of the structural and functional characteristics of the prognostic ability of children with hearing impairment compared with children with neurotypical development is significant. Objective. To learn about the ability of hearing-impaired preschoolers to anticipate future situations. Design. The empirical study involved 50 children aged 5–7 years with hearing impairment and without developmental disabilities, attending preschool educational institutions of the Republic of Tatarstan. The following methods were used: “Ugadaika” [“Guessing Game”] (L.I. Peresleni, V.L. Podobed) and the authors’ methodology “Prognostic Stories”, developed by teachers at Kazan Federal University. Results. In children with hearing impairment, we identified ineffective methods of carrying out predictive activities, irrational forecasting strategies, forecasting difficulties in certain areas of relationships and activities, as well as problems of mastering the rules in a normative situation. Conclusion. The study confirmed the importance of external regulation in the social life of a child with a hearing impairment, which helps the children to predict more successfully in organized activities than in free ones. The most developed relationships in children with hearing impairment are in the child — parent domain. In their own forecasting, children with hearing impairment are more characterized by a passive position; in most situations, the children pointed to other participants, most often adults, as the subjects of future events.

Measurement Invariance Analysis of the Parental Stress Index

While parenting research continues to compare similarities and differences in mothers’ and fathers’ behaviors based on mean values on the respective dimensions, measurement invariance as a prerequisite for these comparisons has seldom been assured. The present study thus subjected the well-known Parenting Stress Index (PSI), widely used in models of family functioning, to a rigorous measurement invariance analysis based on ( N = 214) Austrian couples with children younger than 3 years of age. We evaluated configural, metric, scalar, and uniqueness invariance on item and subscale levels, and tested for structural invariance of means and variances of the PSI parent and child domain by second-order confirmatory factor analyses. As a result, only measurement differences on the scalar levels affected the factor scores, though negligibly. On the structural levels, no differences were found on the PSI child domain across parents, but on the PSI parent domain, mothers reported more stress.
