RESUMEN
Canine atopic dermatitis (AD) is associated with increased levels of allergen-specific IgE due to hyper-sensitization to environmental allergens. Intradermal testing (IDT) and allergen-specific IgE serology testing are often used to determine the allergens which elicit an IgE response in animals with a diagnosis of AD. The objective of this study was to determine the effects of oclacitinib on IDT and allergen-specific IgE serology testing using a laboratory model of house-dust mite sensitized Beagle dogs. Twenty-four (24) normal, healthy purpose-bred Beagle dogs were sensitized to house dust mites (HDM, Dermatophagoides farinae) and randomly assigned to placebo-, oclacitinib- (0.4 mg/kg/dose PO), or prednisolone-treated (0.5 mg/kg/dose PO) groups. After 14 days of twice daily dosing, the effects of prednisolone and oclacitinib were compared to placebo using baseline and post-dose IDT and allergen-specific IgE serum measurements. Sensitized dogs had increased circulating HDM-specific IgE for at least two weeks post-sensitization. Prednisolone significantly inhibited the measurable sensitivity of IDT, while oclacitinib did not. Neither prednisolone nor oclacitinib imposed significant effects on allergen-specific IgE serum levels, suggesting oclacitinib may have potential to be used in dogs concurrently undergoing intradermal skin testing and/or allergen-specific IgE serology testing without interference with test results.

This project is a community case study implemented by local professionals and caregivers to improve the quality of caregiving in two Kazakhstan institutions for infants and toddlers. Local professionals first received comprehensive training by an international team experienced in relevant research-based practices, and then the locals trained institutional staff. Over nearly 2 years, one institution progressively implemented changes in three wards and the other institution in one ward. The changes attempted to make the institution more family-like (e.g., smaller groups and fewer and more consistent caregivers) and caregivers behave more parent-like (e.g., more warm, sensitive, responsive interactions and relationships) without changing nutrition or medical care. Of the 45 children given some exposure to the emerging new wards, 11 experienced the fully revised wards for at least 4 months during their first 2 years of life. They displayed substantial increases in their physical growth, especially those entering in their first year of life, in contrast to the unchanging developmental patterns of 165 children who were reared in the two institutions before the ward changes were made. Physical growth is a commonly used standard of developmental well-being in institutions. Research shows it is sensitive to infants' psychosocial environment, and improvements in physical growth are related to children's cognitive and social-emotional development. Although this pilot community case study had only a few infants fully exposed to the complete ward changes and lacked characteristics of a research experiment, these results are consistent with children's developmental improvements reported in larger scientific studies of similar interventions. This project is an example of how some research-based practices are likely to be implemented in communities in the future. Specifically, it shows that local communities can successfully improve the rearing conditions within institutions, which improve the children's development, and may contribute to the success of their subsequent foster placement and adoption.
RESUMEN
This study is a post-adoption follow-up of a social-emotional intervention in St. Petersburg, Russian Federation Baby Homes (BHs). Children previously resided in BHs and received Care as Usual (CAU, N=220), Training Only (TO, N=94), or Training plus Structural Changes (T+SC, N=45). This study examined intervention effects 0-6.5 years post-adoption to the USA, at age 9 months to 7 years old. Adoptive parents completed questionnaires on their child's social and behavioral development. Intervention graduates had better attachment security, less indiscriminate friendliness, and fewer behavior problems than CAU graduates. Children who had longer exposure to intervention conditions had better attachment security, but poorer executive function, externalizing and internalizing problems, and competence. Thus, although post-institutionalized children were generally functioning in the normal range in early childhood and effect sizes were small, a social-emotional intervention in institutions is associated with modest benefits to attachment and behavior problems and apparent decrements to executive function.
RESUMEN
We review a series of interrelated studies on the development of children residing in institutions (i.e., orphanages) in the Russian Federation or placed with families in the USA and the Russian Federation. These studies rely on a single population, and many potential parameters that typically vary in the literature are similar across studies. The conceptual focus is on the role of early caregiver-child interactions and environmental factors that influence those interactions in children's development. Generally, children residing in institutions that provided minimal caregiver-child interactions displayed delayed physical, cognitive, and social-emotional development. Children and adolescents adopted from such institutions at 18 months of age or older had higher rates of behavioral and executive function problems, even many years after adoption. An intervention that improved the institutional environment by increasing the quality of caregiver-child interactions-without changes in nutrition, medical care, sanitation, and safety-led to substantial increases in the physical, cognitive, and social-emotional development of resident children with and without disabilities. Follow-up studies of children in this intervention who were subsequently placed with USA and Russian families revealed some longer-term benefits of the intervention. Implications are discussed for theoretical understanding of the role of early caregiver-child interactions in development as well as for practice and policy.

The current study addressed whether two institution-wide interventions in St. Petersburg, Russian Federation, that increased caregiver sensitivity (Training Only: TO) or both caregiver sensitivity and consistency (Training plus Structural Changes: T+SC) promoted better socioemotional and cognitive development than did a No Intervention (NoI) institution during the first year of life for children who were placed soon after birth. It also assessed whether having spent less than 9 versus 9 to 36 months with a family prior to institutionalization was related to children's subsequent socioemotional and cognitive development within these three institutions. The Battelle Developmental Inventory (J. Newborg, J.R. Stock, L. Wnek, J. Guidubaldi, & J. Svinicki, 1988) was used to assess the socioemotional and cognitive functioning of children in NoI (n = 95), TO (n = 104), and T+SC (n = 86) at two to three time points during their first 6 to 12 months of residency. Results suggest that improving caregiver sensitivity can improve the cognitive development of infants in the first year of institutionalization whereas improving caregiver consistency in addition to sensitivity is more beneficial for socioemotional development than is sensitivity alone. Similarly, for children in T+SC, longer time with a family prior to institutionalization (consistent caregiver, unknown sensitivity) was associated with better socioemotional, but not cognitive, baseline scores and more rapid cognitive than socioemotional development during institutionalization. These results suggest caregiver sensitivity is more highly related to cognitive development whereas caregiver consistency is more related to socioemotional development in the first years of life.

This study examined the effect of a social-emotional intervention implemented in one St. Petersburg (Russian Federation) institution (called a Baby Home, BH) on the general behavioral development of preterm children (gestational ages of 30-36 weeks) during their first two years of life. The intervention consisted of training caregivers and implementing structural changes to create a more family-like environment. The study included preterm (N = 56) and full-term (N = 93) children from one BH that implemented the intervention and from another BH with no intervention. Children were assessed at 3, 6, 9, 12, 18 and 24 months of age with the Battelle Development Inventory (LINC Associates, 1988). The results showed that the intervention positively influenced the general behavioral development of BH preterm children throughout their first two years of life compared to preterms from the no-intervention BH. Also, results indicated that the intervention effect was developmentally similar for preterm and for full-term children, but preterm children consistently scored lower than full-terms during their first two years living in the BH. In general, our research emphasizes the crucial role of warm, sensitive, and responsive interactions with a constant and emotionally available caregiver for healthy child development for both term and preterm children.
RESUMEN
STUDY OBJECTIVE: To assess the effects of the Seventeen Days interactive video on young women's perceived self-efficacy for using condoms 6 months after being offered the intervention, relative to a control. DESIGN: Multisite randomized controlled trial. SETTING: Twenty participating health clinics and county health departments in Ohio, Pennsylvania, and West Virginia. PARTICIPANTS: Sexually active female adolescents ages 14 to 19 years. INTERVENTIONS: Seventeen Days (treatment intervention; sex education) vs Driving Skills for Life (control intervention; driving education). MAIN OUTCOME MEASURES: Perceived self-efficacy for condom use. RESULTS: Participants in the Seventeen Days group reported higher perceived condom acquisition self-efficacy after 6 months than those in the driving group. This finding held after controlling for baseline self-efficacy scores and other covariates. CONCLUSION: The Seventeen Days program shows promise to improve perceived self-efficacy to acquire condoms among sexually active female adolescents-an important precursor to behavior change.

This report describes a secondary analysis of data from a comprehensive intervention project which included training and structural changes in three Baby Homes in St. Petersburg, Russian Federation. Multiple mediator models were tested according to the R.M. Baron and D.A. Kenny () causal-steps approach to examine whether caregiver-child interaction quality, number of caregiver transitions, and group size mediated the effects of the intervention on children's attachment behaviors and physical growth. The study utilized a subsample of 163 children from the original Russian Baby Home project, who were between 11 and 19 months at the time of assessment. Results from comparisons of the training and structural changes versus no intervention conditions are presented. Caregiver-child interaction quality and number of caregiver transitions fully mediated the association between intervention condition and attachment behavior. No other mediation was found. Results suggest that the quality of interaction between caregivers and children in institutional care is of primary importance to children's development, but relationship context may play a less direct mediational role, supporting caregiver-child interactions.

In studies of children adopted from institutions, being raised in an institution has been associated consistently with an increased risk of persistent cognitive, academic, and social-emotional problems. These findings raise questions about the neurocognitive mechanisms that contribute to these negative outcomes. Theory and models based on studies of animals indicate that development of the prefrontal cortex (PFC) and executive function (EF) may be particularly susceptible to environmental influences during early childhood. In this article, we review recent studies of postinstitutionalized children that examined EF components such as inhibitory control, working memory, shifting, and planning. We then describe emerging research on the structure and function of the PFC. Converging evidence suggests both EF difficulties and alterations in development of the PFC following early institutionalization. We conclude by discussing possible explanations for these findings and implications for prevention and intervention, and by offering suggestions for ongoing research.
RESUMEN
This study assessed social skills in post-institutionalized (PI) children with respect to age-at-adoption, age-at-assessment, and gender. Parent ratings of social skills (Social Skills Rating System) and behavior problems (Child Behavior Checklist) were obtained for 214 children and 127 adolescents who were adopted from socially-emotionally depriving Russian institutions. Results showed that children adopted before 18 months of age have better social skills than those adopted after this age; those assessed in childhood demonstrate better social skills than those assessed in adolescence. PI females, especially later-adopted adolescents, have particularly poor social skills. Children with poor social skills tend to have higher rates of behavior problems.
RESUMEN
A total of 149 children, who spent an average of 13.8 months in Russian institutions, were transferred to Russian families of relatives and nonrelatives at an average age of 24.7 months. After residing in these families for at least 1 year (average = 43.2 months), parents reported on their attachment, indiscriminately friendly behavior, social-emotional competencies, problem behaviors, and effortful control when they were 1.5-10.7 years of age. They were compared to a sample of 83 Russian parents of noninstitutionalized children, whom they had reared from birth. Generally, institutionalized children were rated similarly to parent-reared children on most measures, consistent with substantial catch-up growth typically displayed by children after transitioning to families. However, institutionalized children were rated more poorly than parent-reared children on certain competencies in early childhood and some attentional skills. There were relatively few systematic differences associated with age at family placement or whether the families were relatives or nonrelatives. Russian parent-reared children were rated as having more problem behaviors than the US standardization sample, which raises cautions about using standards cross-culturally.

This study examined whether interventions in Russian Baby Homes promoting warm, sensitive, and responsive caregiver-child interactions and relationships would be associated with advantages in those children's behavior years after they transitioned to family care. Children (N = 135) who had resided for at least 3 months (M = 13.8 months) in one of three intervention institutions were subsequently placed in Russian families (relatives or non-relatives) for at least 1 year (M = 33.5 months). When children were 1.5-10.8 years of age, parents provided ratings of attachment, indiscriminate friendliness, executive functioning, social-emotional development, and behavior problems. Despite very substantial differences in the developmental status of children at departure from the three institutions, there were fewer than expected significant differences between children from the three institutions at follow-up or as a function of being placed with relatives or non-relatives. Specifically, children reared in the most improved institution displayed less indiscriminate friendliness, were less aggressive/defiant, and had less externalizing behavior. Children from all three institutions who were placed into families at older ages tended to be rated more poorly on some measures. These results suggest that previously institutionalized children adjust well to family life, but improved institutional caregiving can have some persistent benefits over several years in children transitioned to families.
RESUMEN
BACKGROUND: Pruritus is a characteristic clinical sign of allergic skin conditions including atopic dermatitis (AD) in the dog. IL-31 is a cytokine found in the serum of some dogs with AD and can induce pruritic behaviours in laboratory beagle dogs. HYPOTHESIS/OBJECTIVES: The objectives were to characterize an IL-31-induced pruritus model by evaluating the efficacy of prednisolone, dexamethasone and oclacitinib, and to compare the speed of anti-pruritic effects of oclacitinib against those of prednisolone and dexamethasone. ANIMALS: Purpose-bred beagle dogs were used in all studies. METHODS: Randomized, blinded, placebo-controlled studies were designed to evaluate and compare the anti-pruritic properties of prednisolone, dexamethasone and oclacitinib following a single intravenous injection of recombinant canine IL-31. Video surveillance was used to monitor and score pruritic behaviours in study animals. RESULTS: Prednisolone [0.5 mg/kg, per os (p.o.)] reduced IL-31-induced pruritus when given 10 h prior to observation. When the time interval between drug treatment and observation was shortened to 1 h, dexamethasone (0.2 mg/kg, intramuscular) but not prednisolone (0.25 or 0.5 mg/kg, p.o.) reduced IL-31-induced pruritus. Oclacitinib (0.4 mg/kg, p.o.) reduced pruritus when given 1, 6, 11 and 16 h prior to the observation period, and the anti-pruritic activity of oclacitinib was greater when compared to prednisolone and dexamethasone at all time points assessed. CONCLUSION AND CLINICAL IMPORTANCE: The efficacy of prednisolone, dexamethasone and oclacitinib in the IL-31-induced pruritus model gives confidence that this may be a relevant model for acute pruritus associated with allergic dermatitis including AD and can be used to evaluate novel compounds or formulations.

Children who spend their early life in social-emotionally depriving institutions have limited opportunities to engage in relationships. This early experience has been associated with many problematic behavioral outcomes; however, researchers have not frequently examined relationship quality of post-institutional adoptees, nor have they examined aspects of the adoptive family that might moderate institutionalization effects. The purpose of this study was to examine the self-reported relationship quality of 10-17-year-old children adopted into the USA from Russian institutions and to determine whether sibling characteristics (relative age, gender composition, sibling adoption status) moderate institutionalization effects. Older age at adoption was related to poorer friendship and sibling, but not mother, relationship quality. Older siblings and same-sex siblings buffered children from this negative age-at-adoption association.

This Special Issue includes articles that contribute to (a) the global research base pertaining to the development of infants and toddlers at risk, primarily those who are institutionalized in lower resource countries; (b) interventions in institutions and to promote family alternatives to institutionalization; and (c) attempts to create modern child welfare systems emphasizing family care in entire states and countries. This introduction places these articles into the broader contexts of the literature in these three domains of interest. Across the world, urbanization, migration, armed conflict, epidemics, and famine disrupt families. Add poverty, abuse, neglect, and parental incapacity due to substance abuse and mental health problems, and the result is millions of children without parental care who come under governmental responsibility, often to be reared in institutions, and at risk for long-term developmental deficiencies and problems. Over the last 2 decades and especially recently, national and international governments and nongovernment organizations have increased efforts to help such children, especially those in low-resource countries. Two types of efforts have been made: one to improve the quality of care provided by institutions and the other to minimize the use of institutions and promote family residential care alternatives. The latter effort includes preventing family separations in the first place, reunification of children with birth families, and developing systems of kinship care, foster care, and adoption. This Special Issue of IMHJ is devoted to reports pertaining to issues in the research knowledge base, program practices, and countrywide policies for infants and young children at risk. We attempt in this introduction to place these reports in the broader context of this field, identify their unique contributions, and highlight lessons learned that can contribute to improved care practices and better child welfare systems.

Behavior problems were studied in fifty 5- to 8-year-old children transferred from a socioemotionally depriving Russian institution to domestic families. Results indicated that the postinstitutional (PI) sample as a whole had higher clinical/borderline behavior problem rates on the parent-reported Child Behavior Checklist for Ages 6-18 (T.M. Achenbach & L.A. Rescorla, 2001) aggressive and lower rates on the withdrawn/depressed and internalizing problems scales than did non-institutionalized (non-I) children reared in Russian families. Compared with the U.S. standardization sample, PI children had significantly higher rates for aggressive, externalizing, and social problems; the non-I children had higher rates for withdrawn/depressed and internalizing problems; and both groups had higher rates for rule-breaking behavioral problems. PI children placed in domestic families at 18 months or older had higher rates of problems than did the U.S. non-I standardization sample, but children placed at younger ages did not. PI children transferred to nonbiological families had lower rates of problems compared to U.S. norms than did children transferred to biological families. Thus, prolonged early socioemotional deprivation was associated with a higher percentage of behavior problems in children placed in domestic families, especially if transferred to biological families.

BACKGROUND AND SCOPE: The focus of this review is on institutionalized children, one of the most inequitably and severely treated groups of children. Although institutions vary, many share some common characteristics, including large groups, high children: caregiver ratios, many and changing caregivers, and caregiver-child interactions that lack warm, sensitive, contingently-responsive, and child-directed behaviors. Resident children develop poorly physically, mentally, and social-emotionally, but those adopted from institutions display substantial catch-up growth in many domains of development. If they are adopted at an early age, there have been no long-term consequences of institutionalization yet measured; but if institutionalization is prolonged, they display higher rates of long-term deficiencies and problems in many domains. METHODS: This review is based on a database search of the literature, focusing on the development of children while residents, and the development of post-institutionalized children who have been transitioned from institutions to family care. It also draws on the reports and findings of the St. Petersburg-USA Orphanage Intervention. FINDINGS: A combination of theories pertaining to attachment (especially caregiver attachment to the infant/toddler), chronic stress, and genetics may explain these outcomes. It appears that caregiver-child interactions are a major contributor to children's outcomes, and interventions in institutions that improve such interactions produce substantial increases in children's physical, mental, and social-emotional development, including for children with disabilities. CONCLUSIONS: Deinstitutionalization and the creation of comprehensive professional child welfare systems emphasizing family care alternatives is a preferred goal, but this is likely to take many low-resource countries decades to develop. If substantial numbers of children remain in institutions despite best efforts to find families for them, improving the institutions might help to provide all the children with the best care possible under the circumstances.
RESUMEN
Selective responding bias, though under-researched, is of particular concern in the study of post-institutionalized children because many studies rely on mailed questionnaires and response rates are often low. The current study addresses the impact of selective responding in a single wave of data collection and in a multi-wave study. Participants were 121 parents from a larger four-wave study of post-institutionalized children, identified as Never Responders, Previous Responders (but not to the current wave), or Wave 4 Responders. Parents were telephoned and asked about their adopted child's family, school, peer, and behavioral adjustment. The children (47% male) ranged in age from 2 to 20 years (M = 10.79, SD = 4.59) and had been adopted between 5 and 54 months of age (M = 15.49, SD = 9.94). There were no differences in parent ratings of adjustment for a single wave of data collection; however, participants who never responded reported poorer family and peer adjustment than those who had responded to at least one wave of data collection. Within a single wave of data collection, there was no evidence that selective responding contributes much bias. Over a multi-wave study, however, results may under-represent adjustment difficulties, especially with family and friends.
RESUMEN
This article reports the maintenance of one of the largest interventions conducted in St. Petersburg (Russian Federation) orphanages for children birth to 4 years using regular caregiving staff. One orphanage received training plus structural changes, another training only, and a third business as usual. The intervention produced substantial differences between these institutions on the Home Observation for Measurement of the Environment (HOME) Inventory and on the Battelle Developmental Inventory scores for children. These institutional differences in HOME scores (N = 298) and Battelle scores for children (N = 357) departing the institutions for families in St. Petersburg and the United States were maintained for at least 6 years after the intervention project. This result may be associated with certain features of the intervention and activities conducted during the follow-up interval.

Inhibitory control and working memory were examined in post-institutionalized (PI) children adopted into United States families from Russian institutions. The PI sample originated from institutions that were less severely depriving than those represented in previous studies and approximated the level of psychosocial deprivation, which is characterized by adequate physical resources but a lack of consistent and responsive caregiving. PI children (N = 75; 29 male) ranged in age from 8-17 years (M = 12.97; SD = 3.03) and were grouped according to whether they were adopted after 14 months or before 9 months. A non-adopted comparison group (N = 133; 65 male) ranged in age from 8-17 years (M = 12.26; SD = 2.75). PI children adopted after 14 months of age displayed poorer performance on the stop-signal and spatial span tasks relative to PI children adopted before 9 months of age after controlling for age at assessment. The two PI groups did not differ in their performance on a spatial self-ordered search task. Older-adopted PI children also showed poorer spatial span task performance compared to non-adopted children, but younger-adopted PI children did not. Task performance was significantly associated with parent-rated hyperactive-impulsive behavior in everyday contexts. These findings suggest that exposure to prolonged early institutional deprivation may be linked with inhibitory control and working memory difficulties years after adoption.
