Preterm infants are at an increased risk of regulatory difficulties during infancy and of behavioral problems in childhood. In the full-term population, persistent crying problems that last beyond 3 months of age have been related to later behavioral problems.

Excessive crying by a preterm infant may reflect an increased risk for later behavioral problems and higher parenting stress even years later. Therefore, it is clinically relevant to assess systematically the crying behavior of preterm infants. (Read the full article)

Sending sexual messages and/or pictures (sexting) has been associated with sexual intercourse among high school–age students.

This study is the first to examine sexting’s prevalence among at-risk middle school students and its associations with a range of sexual behaviors. It also examines differences in sexual risk between sending sexual messages and sexual photos. (Read the full article)

Children who have experienced early psychosocial deprivation are at high risk of persistent, socially indiscriminate behaviors. These behaviors may decline slowly with high-quality caregiving but generally are associated with ongoing impairment.

This study suggests that placement in foster care reduces indiscriminate behaviors to an intermediate level between those in institutional care and community control subjects. It also demonstrates the importance of disorganized early attachment in predicting later indiscriminate behaviors. (Read the full article)

Concerns have been raised that human papillomavirus (HPV) vaccination could lead to riskier behaviors in vaccinated adolescents, but it is unknown whether changes in risk perceptions after vaccination lead to riskier sexual behaviors.

Risk perceptions following HPV vaccination were not associated with subsequent riskier sexual behaviors in sexually experienced and inexperienced young women. These data contribute to the growing evidence that HPV vaccination does not lead to changes in sexual behaviors among adolescents. (Read the full article)

Existing literature indicates relationships between BMI, physical activity, sleep patterns, eating behavior, and health-related quality of life in children and adolescents. However, many previous studies have used non–preference-based instruments, which are not suitable for application within economic evaluation.

The Child Health Utility 9D, a new preference-based health-related quality of life instrument for application in economic evaluation in children and adolescents, revealed stronger associations between utilities and sleep patterns or eating behavior than with BMI, physical activity, or sedentary behavior.

Although expert consensus and previous literature document the importance of early feeding and activity behaviors and practices in preventing obesity and the risks of early rapid weight gain, few studies have rigorously assessed obesity-related behaviors by caregivers of infants.

This study demonstrates the high prevalence of behaviors thought to increase risk for obesity in a diverse, large sample of parent/2-month-old dyads and finds that many behaviors vary by race and ethnicity, suggesting the potential for culturally tailored interventions. (Read the full article)

Integrated or collaborative care intervention models have revealed gains in provider care processes and outcomes in adult, child, and adolescent populations with mental health disorders. However optimistic, conclusions are not definitive due to methodologic limitations and a dearth of studies.

This randomized trial provides further evidence for the efficacy of an on-site intervention (Doctor Office Collaborative Care) coordinated by care managers for children's behavior problems. The findings provide support for integrated behavioral health care using novel provider and caregiver outcomes. (Read the full article)

One in 4 children with cerebral palsy (CP) have a behavioral disorder. Parenting interventions are an efficacious approach to treating behavioral disorders. There is a paucity of research on parenting interventions with families of children with CP.

This is the first study to demonstrate the efficacy of a parenting intervention in targeting behavioral problems in children with CP. Further, results suggest that Acceptance and Commitment Therapy delivers additive benefits above and beyond established parenting interventions. (Read the full article)

Investigations of adolescents’ sexual risk behavior have focused on factors such as parental monitoring, deviant peer affiliation, and daring that occur during early and midadolescence. Less is known about early childhood precursors to adolescent sexual risk behavior.

This prospective longitudinal study identifies parenting practices and mothers’ depressive symptomatology during early childhood as precursors to later sexual risk behavior and involvement in pregnancy in adolescent boys, with deviant peer affiliation during emerging adolescence mediating these relationships.

Children who have syndromic craniosynostosis are at risk for developing intellectual disability, behavioral and emotional problems. Study results were often based on small samples and wide age-based variation, using non-validated instruments and describing no clear inclusion and exclusion criteria.

Intellectual, behavioral, and emotional functioning is described in a national sample (N = 82) of school-aged children with syndromic craniosynostosis. Using standardized instruments, this study indicates higher risks for intellectual disability and behavioral problems mainly in children having Apert and Muenke syndromes. (Read the full article)

In addition to seizures, school-aged children with epilepsy can have coexisting cognitive and behavioral difficulties, but the spectrum and prevalence of such difficulties are uncertain.

This study provides population-based data on the prevalence of common comorbid cognitive impairments and factors associated with such diagnoses in school-aged children with "active" epilepsy. (Read the full article)

Sending and receiving sexually explicit picture and text messages (sexting) is related to sexual activity and risk behavior among some high school populations, yet little is known about sexting associations with sexual activity and risk behavior among middle school students.

This study is the first to examine sexting among a probability sample of middle school students and found that middle school students who text excessively and send and receive sexts are more likely to report being sexually active. (Read the full article)

Graduating from high school is associated with better health and health behaviors. However, no rigorous studies have tested whether exposure to a high-performing school improves health or health behaviors, thus the causal relationship is unknown.

Exposure to successful schools can reduce very risky health behaviors among low-income adolescents. The primary mechanism is mostly due to better school retention and also due to better academic achievement. (Read the full article)

To date, studies of adaptive behavior in fragile X syndrome have focused on particular age points, either longitudinally or cross-sectionally across a broad age spectrum. Studies have shown variable patterns in adaptive behavior among people with fragile X syndrome.

This study fills a critical gap in knowledge about the profile of adaptive behavior across childhood, adolescence, and young adulthood in fragile X syndrome. This study is the first to incorporate longitudinal data from an age-matched typically developing group. (Read the full article)

Children with cognitive delay have been shown to have more behavior problems than typically developing children; however, few studies have investigated this relationship over time or among very young children.

Our findings provide some of the first national, prospective evidence that having a cognitive delay may place children at risk for developing and maintaining behavior problems before school age. Early identification and intervention may improve outcomes for these children. (Read the full article)

Behavioral health (BH) screening is known to increase identification of children with BH issues, but in small-scale studies, rates of follow-up after screening have been reported to be low.

This study examines the relationship between BH screening and the receipt of BH services in Massachusetts Medicaid children. Nearly 60% of children identified with BH problems received BH services, but only 30% of newly identified children received BH services. (Read the full article)

The single-family room (SFR) NICU is a major response to improve care and reduce developmental morbidity in preterm infants. However, no studies have examined how and why this model is associated with changes in medical and neurobehavioral outcome.

This study shows improved medical and neurodevelopmental outcome in infants hospitalized in the SFR model of care. More important, improvements occurred specifically in relation to increases in maternal involvement and developmental support afforded by the SFR environment. (Read the full article)

Cross-sectional research indicates that teen sexting is common, may be associated with other adolescent behaviors such as substance use, does not appear to be a marker of mental well being, and is probably an indicator of actual sexual behaviors.

Although mounting evidence links teen sexting to sexual behavior, little is known about the temporal sequencing of these 2 behaviors. Knowing which comes first will aid tween- and teen-focused health care providers in their interaction with patients and patients’ parents. (Read the full article)

Research suggests that appearance-focused messages and exaggerated depictions of sexual activity in the media negatively influence adolescents’ body and sexual self-perceptions. As adolescents increasingly use the Internet to explore their sexuality, health risks related to online behaviors should be identified.

This 4-wave study examined the prevalence and development of 2 receptive and 2 interactive sex-related online behaviors and their relations with adolescents’ body and sexual self-perceptions. It further investigated which parental strategies regarding Internet use may reduce risky sex-related online behaviors. (Read the full article)

Maternal depression has been associated with adolescent engagement in risky behaviors such as substance use. However, there is a lack of longitudinal research examining timing-specific effects in this relationship.

The results of this study indicate that youth exposed to increasing levels of maternal depressive symptoms in middle childhood are more likely to engage in substance use and delinquent behaviors and have an earlier debut age of these behaviors. (Read the full article)

Exclusive breastfeeding until 6 months of an infant’s age is described as the safest, most powerful and cost-effective intervention to reduce infant morbidity and mortality globally. In developing countries, only ~25% of infants are exclusively breastfed for 6 months.

We developed a psycho-educational intervention combining education with techniques of cognitive-behavioral therapy, integrated it into the routine work of community health workers, which increased the rate and duration of exclusive breastfeeding until 6 months of an infant’s age.

Early first sexual intercourse (FSI) is a risk factor for unplanned teenage pregnancy, sexually transmitted infection, and adverse health outcomes in adolescence and into adulthood. In girls, externalizing behaviors are more strongly associated with earlier FSI than internalizing behaviors.

Externalizing behavior from as early as 5 in boys and 10 in girls is a significant risk factor for earlier age at FSI. Internalizing behavior at ages 8 and 10 was associated with early FSI for boys but not girls. (Read the full article)

Executive functioning and excess weight have been associated in both cross-sectional and prospective studies, but mechanisms explaining this relationship are unclear.

Impulsivity and planning at age 10 predicted age 10 to 16 BMI changes, and age 12 binge-eating tendencies mediated the relation between impulsivity at age 10 and changes in BMI change through age 16. (Read the full article)

Behavioral economics applies key principles from psychology and economics to address obstacles to behavior change. The important topic of pediatric firearm injuries has not yet been explored through a behavioral economic lens. Pediatric firearm-related injuries are a significant public health problem in the United States. Despite American Academy of Pediatrics guidelines advising that firearms be stored unloaded, in a locked box or with a locking device, and separate from ammunition, estimates suggest that ~4.6 million children live in homes with at least 1 loaded and unlocked firearm. In this article, we use behavioral economic theory to identify specific cognitive biases (ie, present bias; in-group, out-group bias; and the availability heuristic) that may influence parental decision-making around firearm storage. We illustrate situations in which these biases may occur and highlight implementation prompts, in-group messengers, and increased salience as behaviorally informed strategies that may counter these biases and subsequently enhance safe firearm storage. We also describe other opportunities to leverage the behavioral economic tool kit. By better understanding the individual behavioral levers that may impact decision-making around firearm storage, behavioral scientists, pediatric providers, and public health practitioners can partner to design and test tailored interventions aimed at decreasing pediatric firearm injuries. Further empirical study is warranted to identify the presence of specific biases and heuristics and determine the most effective behavior change strategies for different subpopulations.

ABSTRACT

The luminous marine Gram-negative bacterium Vibrio (Aliivibrio) fischeri is the natural light organ symbiont of several squid species, including the Hawaiian bobtail squid, Euprymna scolopes, and the Japanese bobtail squid, Euprymna morsei. Work with E. scolopes has shown how the bacteria establish their niche in the light organ of the newly hatched host. Two types of V. fischeri strains have been distinguished based upon their behavior in cocolonization competition assays in juvenile E. scolopes, i.e., (i) niche-sharing or (ii) niche-dominant behavior. This study aimed to determine whether these behaviors are observed with other V. fischeri strains or whether they are specific to those isolated from E. scolopes light organs. Cocolonization competition assays between V. fischeri strains isolated from the congeneric squid E. morsei or from other marine animals revealed the same sharing or dominant behaviors. In addition, whole-genome sequencing of these strains showed that the dominant behavior is polyphyletic and not associated with the presence or absence of a single gene or genes. Comparative genomics of 44 squid light organ isolates from around the globe led to the identification of symbiosis-specific candidates in the genomes of these strains. Colonization assays using genetic derivatives with deletions of these candidates established the importance of two such genes in colonization. This study has allowed us to expand the concept of distinct colonization behaviors to strains isolated from a number of squid and fish hosts.

IMPORTANCE There is an increasing recognition of the importance of strain differences in the ecology of a symbiotic bacterial species and, in particular, how these differences underlie crucial interactions with their host. Nevertheless, little is known about the genetic bases for these differences, how they manifest themselves in specific behaviors, and their distribution among symbionts of different host species. In this study, we sequenced the genomes of Vibrio fischeri isolated from the tissues of squids and fishes and applied comparative genomics approaches to look for patterns between symbiont lineages and host colonization behavior. In addition, we identified the only two genes that were exclusively present in all V. fischeri strains isolated from the light organs of sepiolid squid species. Mutational studies of these genes indicated that they both played a role in colonization of the squid light organ, emphasizing the value of applying a comparative genomics approach in the study of symbioses.

North Carolina is developing a unique and innovative infrastructure to support integrated physical, behavioral, and social health care. Efforts by the North Carolina Department of Health and Human Services, the Foundation for Health Leadership & Innovation, Cone Health, Atrium Health, and the One Charlotte Health Alliance advance our understanding of how to best operationalize the design and payment of integrated services. Best practices such as the collaborative care and primary care behavioral health models reduce inefficiencies and disparities by bringing together teams of primary care and behavioral health care providers.

The vertebrate limb serves as an experimental paradigm to study mechanisms that regulate development of the stereotypical skeletal elements. In this study, we simultaneously inactivated Sall4 using Hoxb6Cre and Plzf in mouse embryos, and found that their combined function regulates development of the proximal-anterior skeletal elements in hindlimbs. The Sall4; Plzf double knockout exhibits severe defects in the femur, tibia, and anterior digits, distinct defects compared to other allelic series of Sall4; Plzf. We found that Sall4 regulates Plzf expression prior to hindlimb outgrowth. Further expression analysis indicated that Hox10 genes and GLI3 are severely downregulated in the Sall4; Plzf double knockout hindlimb bud. In contrast, PLZF expression is reduced but detectable in Sall4; Gli3 double knockout limb buds, and SALL4 is expressed in the Plzf; Gli3 double knockout limb buds. These results indicate that Plzf, Gli3, and Hox10 genes downstream of Sall4, regulate femur and tibia development. In the autopod, we show that Sall4 negatively regulates Hedgehog signaling, which allows for development of the most anterior digit. Collectively, our study illustrates genetic systems that regulate development of the proximal-anterior skeletal elements in hindlimbs.

The Hippo pathway is an evolutionarily conserved signaling network that regulates organ size, cell fate, and tumorigenesis. In the context of organ size control, the pathway incorporates a large variety of cellular cues, such as cell polarity and adhesion, into an integrated transcriptional response. The central Hippo signaling effector is the transcriptional coactivator Yorkie, which controls gene expression in partnership with different transcription factors, most notably Scalloped. When it is not activated by Yorkie, Scalloped can act as a repressor of transcription, at least in part due to its interaction with the corepressor protein Tgi. The mechanism by which Tgi represses transcription is incompletely understood, and therefore we sought to identify proteins that potentially operate together with Tgi. Using an affinity purification and mass-spectrometry approach we identified Pits and CtBP as Tgi-interacting proteins, both of which have been linked to transcriptional repression. Both Pits and CtBP were required for Tgi to suppress the growth of the Drosophila melanogaster eye and CtBP loss suppressed the undergrowth of yorkie mutant eye tissue. Furthermore, as reported previously for Tgi, overexpression of Pits repressed transcription of Hippo pathway target genes. These findings suggest that Tgi might operate together with Pits and CtBP to repress transcription of genes that normally promote tissue growth. The human orthologs of Tgi, CtBP, and Pits (VGLL4, CTBP2, and IRF2BP2) have previously been shown to physically and functionally interact to control transcription, implying that the mechanism by which these proteins control transcriptional repression is conserved throughout evolution.

Repeated alcohol experiences can produce long-lasting memories for sensory cues associated with intoxication. These memories can problematically trigger relapse in individuals recovering from alcohol use disorder (AUD). The molecular mechanisms by which ethanol changes memories to become long-lasting and inflexible remain unclear. New methods to analyze gene expression within precise neuronal cell types can provide further insight toward AUD prevention and treatment. Here, we used genetic tools in Drosophila melanogaster to investigate the lasting consequences of ethanol on transcription in memory-encoding neurons. Drosophila rely on mushroom body (MB) neurons to make associative memories, including memories of ethanol-associated sensory cues. Differential expression analyses revealed that distinct transcripts, but not genes, in the MB were associated with experiencing ethanol alone compared to forming a memory of an odor cue associated with ethanol. Adult MB-specific knockdown of spliceosome-associated proteins demonstrated the necessity of RNA-processing in ethanol memory formation. These findings highlight the dynamic, context-specific regulation of transcription in cue-encoding neurons, and the lasting effect of ethanol on transcript usage during memory formation.
