RESUMO

PURPOSE OF REVIEW: This review explores advances in the utilization of technology to address perinatal mood and anxiety disorders (PMADs). Specifically, we sought to assess the range of technologies available, their application to PMADs, and evidence supporting use. RECENT FINDINGS: We identified a variety of technologies with promising capacity for direct intervention, prevention, and augmentation of clinical care for PMADs. These included wearable technology, electronic consultation, virtual and augmented reality, internet-based cognitive behavioral therapy, and predictive analytics using machine learning. Available evidence for these technologies in PMADs was almost uniformly positive. However, evidence for use in PMADs was limited compared to that in general mental health populations. Proper attention to PMADs has been severely limited by issues of accessibility, affordability, and patient acceptance. Increased use of technology has the potential to address all three of these barriers by facilitating modes of communication, data collection, and patient experience.

RESUMO

Multiple changes and stressors at the family, hospital, and societal levels have resulted from the COVID-19 pandemic that impact the early social environment of infants in Neonatal Intensive Care Unit (NICU) settings. This manuscript reviews these pandemic-related adversities, including hospital-wide visitor restrictions, mask requirements that interfere with caregiver facial expressions, parental anxiety about virus transmission, and reduced support services. We will further describe adaptations to mental health service delivery and approaches to care in the NICU to mitigate increased risk associated with pandemic-related adversities. Adaptations include integration of technology, staff education and support, and delivery of activity kits to encourage parent-infant bonding. Data was collected as part of routine program evaluation of infant mental health services from one 50-bed NICU setting and describes family concerns, barriers to visitation, and utilization of mental health services during the pandemic. Concerns related to COVID-19 rarely emerged as the primary presenting issue by the families referred for infant mental health services from April through December of 2020. However, a number of families indicated that infection concerns and visitation restrictions posed significant challenges to their parenting and/or coping. There were significant discrepancies noted between the visitation patterns of families with public and private insurance. Several adaptations were developed in response to the multiple challenges and threats to infant mental health present during the COVID-19 pandemic.


Múltiples factores de estrés a nivel de la familia, el hospital y la sociedad han resultado de la pandemia del COVID-19, los cuales han tenido un impacto en el temprano ambiente social de los infantes en el ambiente de la Unidad de Cuidados Intensivos Neonatales (NICU). Este artículo revisa estas situaciones adversas relacionadas con la pandemia, incluyendo las restricciones generales de visita al hospital, el requisito de llevar máscara que interfiere con las expresiones faciales de quien presta el cuidado, la ansiedad de los padres acerca de la transmisión del virus y los reducidos servicios de apoyo. Describimos además adaptaciones al ofrecimiento de servicios de salud mental en NICU para mitigar el aumento del riesgo asociado con las situaciones adversas relacionadas con la pandemia. Estas adaptaciones incluyen la integración de tecnología, la educación y el apoyo del personal, así como el ofrecimiento de material para actividades que promueven la unión afectiva entre progenitor e infante. Se recogió información como parte de la evaluación rutinaria del programa sobre los servicios sicosociales en el caso de una unidad NICU de 50 camas y se describen las preocupaciones de la familia, los obstáculos a la visita, así como la utilización de los servicios de salud mental infantil durante la pandemia. El COVID-19 raramente surgió como el principal asunto que enfrentaban las familias que fueron referidas para intervención de abril a diciembre de 2020. Sin embargo, algunas familias indicaron que las preocupaciones de adquirir una infección y las restricciones de visita presentaron retos significativos a la crianza y/o a la manera de arreglárselas. Se notaron discrepancias significativas entre los patrones de visita de familias con seguro público o con seguro privado. Como respuestas a estas amenazas a la salud mental infantil presentes durante la pandemia del COVID-19, se desarrollaron varias adaptaciones.


Des facteurs de stress multiples aux niveaux de la famille, de l'hôpital et de la société ont résulté de la pandémie du COVID-19 qui impacte l'environnement social précoce des nourrissons dans les Unités Néonatales de Soins Intensifs (UNSI). Cet article passe en revue ces adversités liées à la pandémie, y compris les restrictions pour les visiteurs dans les hôpitaux, les obligations de porter le masque qui interfèrent avec les expressions faciales de la personne prenant soin du bébé, l'anxiété parentale à propos de la transmission du virus et des services de soutien réduits. Nous décrivons des adaptations à la prestation de service de santé mentale dans l'UNSI afin de mitiger le risque accru associé aux adversités liées à la pandémie. Des adaptations ont inclus l'intégration de la technologie, la formation et le soutien aux employés, la livraison de kits d'activités afin d'encourager le lien parent-bébé. Des données ont été recueillies comme faisant partie de l'évaluation de routine de services psychosociaux dans le contexte d'une INSI de 50 lits et décrivent les inquiétudes familiales, les barrières aux visites, l'utilisation de services de santé mentale du nourrisson durant la pandémie. Le COVID-19 a rarement émergé comme étant le problème principal présenté par les familles ayant reçu une intervention d'avril à décembre 2020. Cependant certaines familles ont indiqué que les inquiétudes touchant à l'infection et les restrictions des visites ont posé des défis importants à leur parentage et/ou à leur adaptation. Des différences importantes ont été notées entre les patterns de visites des familles ayant une assurance publique et une assurance privée. Plusieurs adaptations ont été développées pour faire face aux dangers pour la santé mentale infantile présents durant la pandémie de COVID-19.

RESUMO

BACKGROUND: Ongoing research is necessary to better understand the causes of autism spectrum disorder (ASD), the developmental outcomes for individuals diagnosed with ASD, and the efficacy of the interventions. However, it is often difficult to recruit sufficient numbers of participants for studies, and despite the prevalence of ASD (currently estimated to affect 1 in 54 children), little research has focused on how to efficiently recruit participants with ASD. OBJECTIVE: The aim of this study was to determine the efficacy of two different paid advertisements-social media and radio advertising-in recruiting participants for a study enrolling people with ASD and their family members by examining the number of participants enrolled, the cost per participant, and the geographic reach of each type of advertising. METHODS: We examined participant enrollment in a study following nonoverlapping paid advertisements on a popular FM radio station (aired in three cities across two states) and Facebook (six advertisements that ran in five cities across two states). The total paid investment in the radio campaign was $12,030 and that in the Facebook campaign was $2950. Following the advertising campaigns, 1391 participants in the study who were affiliated with the Houston, Texas, site received email invitations to participate in a brief survey about the ways in which they learned about the study (eg, social media, medical provider, website) and which of these were most influential in their decisions to participate; 374 (26.8%) of the participants completed this survey. RESULTS: Social media advertising outperformed radio in all three parameters examined by enrolling more participants (338 vs 149), with a lower average cost per participant ($8.73 vs $80.74) and a wider geographic reach, based on a comparison of the number of zip codes within and outside of Texas for questionnaire respondents who rated social media as the most influential method of contact (n=367, χ21=5.85, P=.02). Of the 374 survey participants, 139 (37.2%) reported that they had seen the study on social media prior to enrollment, while only 9 (2.4%) said they heard about it via radio. CONCLUSIONS: Our findings suggest that advertising on social media can efficiently reach a large pool of potential participants with ASD, increasing the likelihood of meeting study enrollment goals. Researchers should consider allocating at least some portion of recruitment dollars to social media platforms as a means of quickly and inexpensively reaching out to their target populations, including for studies with in-person procedures.

RESUMO

This study examines the impact of maternal depression on reductions in children's behavior problems severity following implementation of the Brief Behavioral Intervention-a brief, manualized parent management training treatment. The parents of 87 children aged 2-6 years of age received parent management training at a metropolitan hospital. Parents of participants completed measures of externalizing behavior and maternal depression. The association between pre-post treatment change in externalizing behavior and maternal depression was examined using an autoregressive cross-lagged model. Results showed that self-reported maternal depressive symptoms at pre-treatment negatively influenced the overall magnitude of reduction of reported externalizing behaviors in children following treatment. Results indicate that aspects of family functioning not specifically targeted by parent management training, such as maternal depression, significantly affect treatment outcomes. Clinicians providing parent management training may benefit from assessing for maternal depression and modifying treatment as indicated.

RESUMO

Syntactic adaptation has been shown to occur for various temporarily ambiguous structures, wherein an initially unexpected resolution becomes easier to process after repeated exposure. More controversial and less replicated is the claim that this adaptation towards a locally frequent structure occurs due to a strategic shifting of expectations to match short-term statistical regularities such that readers adapt away from the a priori more frequent structure. Experiment 1 replicates the initial adaptation towards a coordination garden path structure using self-paced reading; however, this paradigm has been criticised for its low reliability for detecting such small effects. To this end, Experiments 2 and 3 use a combination of self-paced reading and sentence completion tasks to replicate initial adaptation towards both coordination and reduced relative garden path structures and show evidence for a preference for these structures over their a priori more frequent alternatives. Together, these data reveal that participants may be tracking local structural statistics in real time; however, they may not be able to rapidly use that information to update processing behaviours.

RESUMO

This study examined classroom behavioral outcomes for children with Attention-Deficit/Hyperactivity Disorder (ADHD) following their participation in a manualized, 10-week intervention called Family Skills Training for ADHD-Related Symptoms (Family STARS). Family STARS combined behavioral parent training (BPT) and child-focused behavioral activation therapy (CBAT). Participants were children ages 7-10 diagnosed with ADHD-Combined Type. Pre- and post-treatment teacher ratings of ADHD symptoms were compared using a single group, within-subjects research design. Intervention effectiveness was analyzed using paired-samples t-tests. Results indicated statistically significant classroom improvements for externalizing behaviors and attention problems with medium and large main effects (respectively) for the intervention. Possible implications for combining CBAT with BPT for the treatment of ADHD are discussed as well as the relevance of these results for improving the effectiveness and portability of empirically supported interventions.

RESUMO

Parent management training is an evidence-based treatment for disruptive behavior. However, the number of treatment sessions can be high, contributing to high attrition rates. The purpose of this study was to examine post-treatment, 6-month, and 1-year treatment outcomes of the Brief Behavioral Intervention. One hundred twenty children aged 2-6.5 years demonstrating clinically significant disruptive behavior were referred to an outpatient clinic for treatment and participated in the study. Attrition was below reported rates in the literature. Significant decreases in child disruptive behavior and parent stress were found from pre-to-post intervention, and improvements were maintained at follow-ups. Significant pre-to-post intervention teacher reported decreases in behavior were reported.

RESUMO

OBJECTIVE: This study aimed to evaluate a novel model of care to improve access to diagnostic evaluations for autism spectrum disorder and/or developmental delays for school-age children. METHODS: An "initial assessment" (IA) model for children aged 7 to 9 years was implemented at a large regional pediatric hospital. Referral patterns and the number of patients evaluated with the IA model were obtained through the electronic health record (EHR). Referral patterns from the EHR were checked against clinician surveys. RESULTS: Total IA volume had a strong negative association with school-age WL volume ( r (22) = -0.92, p < 0.001), indicating that as IA volume increased, the WL volume declined. Evaluation of referral patterns after IAs revealed that approximately 1 in 3 children seen for IA did not require further evaluation and could be immediately removed from the WL. CONCLUSION: Results indicate that implementation of a novel IA model was strongly associated with a decrease in WL volume for neurodevelopmental evaluations of school-age children. These findings support a "right-fit" approach to optimize clinical resources and improve access to neurodevelopmental evaluations.

RESUMO

Attraction effects in comprehension have reliably shown a grammaticality asymmetry in which mismatching plural attractors confer facilitatory interference for ungrammatical verbs, but no processing cost for grammatical verbs. While this has favoured cue-based retrieval accounts of attraction phenomena in comprehension, Patson and Husband offered offline evidence suggesting that comprehenders systematically misrepresent number information in attraction phrases, leaving open the possibility for faulty noun phrase (NP) representations later in processing. The current study employs two self-paced reading discourse experiments to test for number attraction misrepresentations in real time. Specifically, the attraction phrases occurred as embedded direct object phrases, allowing for a direct test of the role of attractor noun number in head noun number misrepresentation (i.e., no number cue from verb). Although no online evidence for misrepresentation was found, a third single-sentence rapid serial visual presentation experiment showed error rates to offline probes corroborating the post-interpretive findings from Patson and Husband, suggesting that a search in memory for associative features may not employ the same processes as the formation of dependencies in discourse comprehension. The findings are discussed in the framework of feature misbinding in memory in line with recent post-interpretive accounts of offline comprehension errors.

RESUMO

CASE: Brian is a 6-year-old boy who was diagnosed with autism spectrum disorder (ASD) and global developmental delay at age 2. He has no other health conditions of note. Brian lives with his parents and an older brother, who also has ASD, in a rural area 2 hours from the center where he was diagnosed. Brian has a history of intermittent self-injurious behaviors (head-banging, throwing himself onto the floor, etc.) that regularly result in bruising, intense and lengthy tantrums, and aggression toward family and teachers. Brian will occasionally indicate items that he wants, but otherwise has no functional communication skills. Over the past 18 months, Brian's challenging behaviors have waxed and waned. The regional special education program is not equipped to safely manage his behaviors, and there are no in-home or center-based agencies that provide applied behavior analysis (ABA) available. Brian's developmental pediatrician initiated guanfacine (eventually adding a small dose of aripiprazole) and referred the family to psychology for weekly telehealth behavioral parent training to address behavioral concerns using the Research Units in Behavioral Intervention curriculum.1Brian's behavioral problems decreased during the initial weeks of the COVID-19 crisis, when he no longer had to leave home or attend special education. However, as summer continued, his behaviors worsened substantially (regular bruising and tissue damage, numerous after-hours consultations with his psychologist and developmental pediatrician, and one trip to the emergency department). The intensity of Brian's behaviors (maintained primarily by access to tangible items and escape from demands) made progress with behavioral supports slow and discouraging for his parents. Other psychosocial stressors coalesced for the family as well, including employment loss, limited social support because of social distancing requirements, and illness of one of his parents. The developmental pediatrician continued to modify the medication regimen over the summer, transitioning Brian from guanfacine to clonidine and increasing his aripiprazole incrementally (with clear increased benefit); hydroxyzine was also used as needed during the episodes of highest intensity.Despite the availability of best-practice guidelines for children with Brian's presenting concerns,2 a confluence of barriers (geographic, economic, ABA work force, global pandemic, etc.) present serious questions for his family and care team related to the next steps in Brian's care. Should he attend in-person school in the fall, knowing that the available program may have limited educational benefit and increase his risk of COVID-19 exposure (not to mention self-injury)? Would the potential benefits of cross-country travel to an intensive behavioral treatment program outweigh the associated psychosocial and economic stressors? How else can the virtual care team support this family? REFERENCES: 1. Bearss K, Johnson C, Smith T, et al.

RESUMO

OBJECTIVE: The purpose of this study is to identify whether the well-described pattern of declining adaptive functioning across age among children with autism spectrum disorder (ASD) also exists among intellectually gifted children with ASD because their cognitive abilities might serve as a protective factor. METHODS: Data from the Simons Simplex Collection were used to identify 51 participants with full-scale intelligence (IQ) scores of 130 or above with this group labeled as the intellectually gifted range (IGR). Two comparison samples of children with IQs in the intellectual disability range (IDR; < 70 Standard Score [SS]) and average range (AR; 85-115 SS) were created based on matching of age (±2 years), maternal education level, and sex. RESULTS: Multivariate analysis of variance indicated a main overall effect for the IQ group on a measure of adaptive skills (Λ = 0.61, F(6, 296), p < 0.001). Post hoc comparisons revealed that the IDR group scored lower on all subscales than the AR and IGR groups, but the scores between the latter groups did not differ from one another in socialization and daily living skills (DLS) domains. Age was negatively correlated with adaptive communication scores in all groups but only associated with socialization and DLS domain scores in the IGR group (r = -0.51 and -0.48, respectively). CONCLUSION: The findings suggest that intellectual giftedness does not serve as a protective factor against age-related declines in adaptive functioning among individuals with ASD.

RESUMO

OBJECTIVE: To identify factors associated with gastrostomy tube (GT) placement in infants with congenital diaphragmatic hernia (CDH). METHODS: Retrospective cohort study of 114 surviving infants with CDH at a single tertiary care neonatal intensive care unit from 2010-2019. Prenatal, perinatal and postnatal characteristics were compared between patients who were discharged home with and without a GT. Prenatal imaging was available for 50.9% of the cohort. Logistic regression was used to assess the association between GT placement and pertinent clinical factors. ROC curves were generated, and Youden's J statistic was used to determine optimal predictive cutoffs for continuous variables. Elastic net regularized regression was used to identify variables associated with GT placement in multivariable analysis. RESULTS: GT was placed in 43.9% of surviving infants with CDH. Prenatal variables predictive of GT placement were percent predicted lung volume (PPLV) <21%, total lung volume (TLV) <30 ml, lung-head ratio (LHR) <1.2 or observed to expected LHR (O/E LHR) <55%. Infants who required a GT were diagnosed earlier prenatally (23.6 ± 3.4 vs. 26.4 ± 5.6 weeks). Patients whose stomach was above the diaphragm on prenatal ultrasound (up) had a higher odds of GT placement compared to those with stomachs below the diaphragm (down) position by a factor of 2.9 (95% CI: 1.25, 7.1); p = 0.0154. Postnatally, infants with GT had lower Apgar scores at 1 and 5 min, longer lengths of stay and higher proportion of flap closures. Infants with a type C or D defect and extracorporeal membrane oxygenation (ECMO) were associated with increased odds of needing a GT. Postnatal association included being NPO for >12 days, need for transpyloric (TP) feeds for >10 days, >14 days to transition to a 30 min bolus feed, presence of gastro-esophageal reflux (GER), chronic lung disease and pulmonary hypertension. In multivariable analysis, duration of NPO, time to TP feeds, transition to 30 min bolus feeds remained significantly associated with GT placement after adjusting for severity of pulmonary hypertension (PH), GER diagnosis and sildenafil treatment. CONCLUSION: Identification of risk factors associated with need for long-term feeding access may improve timing of GT placement and prevent prolonged hospitalization related to feeding issues. LEVEL OF EVIDENCE RATING: Level II (Retrospective Study).

RESUMO

Previous work has ostensibly shown that readers rapidly adapt to less predictable ambiguity resolutions after repeated exposure to unbalanced statistical input (e.g., a high number of reduced relative-clause garden-path sentences), and that these readers grow to disfavor the a priori more frequent (e.g. main verb) resolution after exposure (Fine, Jaeger, Farmer, & Qian, 2013). However, recent work has failed to replicate effects indicating a penalty for the a priori preferred, more frequent continuation, despite finding a speedup in syntactic repair times after initial exposure to the dispreferred, infrequent structure (Harrington Stack, James, & Watson, 2018). The current study reports three self-paced reading experiments that test whether co-occurring cues (explicit comprehension questions, preceding semantic cues, and font color) help facilitate adaptation to reduced relative/main verb garden-path sentences. Results suggest that readers do not overcome preexisting expectation biases by rapidly adapting to statistically novel linguistic contexts even with convergent probabilistic cues. An emphasis is placed on the difference between syntactic satiation effects and expectation adaptation, the latter of which we argue can only be determined through a penalty for an a priori preferred resolution after repeated exposure to its a priori less-preferred counterpart.

RESUMO

The combined influence of oncogenic drivers, genomic instability, and/or DNA damage repair deficiencies increases replication stress in cancer. Cells with high replication stress rely on the upregulation of checkpoints like those governed by CHK1 for survival. Previous studies of the CHK1 inhibitor prexasertib demonstrated activity across multiple cancer types. Therefore, we sought to (1) identify markers of prexasertib sensitivity and (2) define the molecular mechanism(s) of intrinsic and acquired resistance using preclinical models representing multiple tumor types. Our findings indicate that while cyclin E dysregulation is a driving mechanism of prexasertib response, biomarkers associated with this aberration lack sufficient predictive power to render them clinically actionable for patient selection. Transcriptome analysis of a pan-cancer cell line panel and in vivo models revealed an association between expression of E2F target genes and prexasertib sensitivity and identified innate immunity genes associated with prexasertib resistance. Functional RNAi studies supported a causal role of replication fork components as modulators of prexasertib response. Mechanisms that protect cells from oncogene-induced replication stress may safeguard tumors from such stress induced by a CHK1 inhibitor, resulting in acquired drug resistance. Furthermore, resistance to prexasertib may be shaped by innate immunity.

RESUMO

Using a rat model of craving and relapse, we have previously found time-dependent increases in cue-induced cocaine seeking over the first months of withdrawal from cocaine, suggesting that drug craving incubates over time. Here, we explored the role of the amygdala extracellular signal-regulated kinase (ERK) signaling pathway in this incubation. Cocaine seeking induced by exposure to cocaine cues was substantially higher after 30 withdrawal days than after 1 withdrawal day. Exposure to these cues increased ERK phosphorylation in the central, but not the basolateral, amygdala after 30 d, but not 1 d, of withdrawal. After 30 d of withdrawal from cocaine, inhibition of central, but not basolateral, amygdala ERK phosphorylation decreased cocaine seeking. After 1 d of withdrawal, stimulation of central amygdala ERK phosphorylation increased cocaine seeking. Results suggest that the incubation of cocaine craving is mediated by time-dependent increases in the responsiveness of the central amygdala ERK pathway to cocaine cues.

RESUMO

OBJECTIVES: To examine screening practices for autism spectrum disorder (ASD), subsequent referrals, and diagnostic outcomes within a large network of primary pediatric care practices. METHODS: Rates of ASD screening with the Modified Checklist for Autism in Toddlers (M-CHAT) at 18- and 24-month well-child visits were examined among 290 primary care providers within 54 pediatric practices between June 2014 and June 2016. Demographic, referral, and diagnostic data were abstracted from the medical records for all children who failed the M-CHAT (ie, score of ≥3) at either or both visits. RESULTS: Rates of M-CHAT screening were 93% at 18 months and 82% at 24 months. Among 23 514 screens, scores of 648 (3%) were ≥3 (386 at 18 months, 262 at 24 months) among 530 unique children who failed 1 or both screenings. Among screen-failed cases, 18% received a diagnosis of ASD and 59% received ≥1 non-ASD neurodevelopmental disorder diagnosis within the follow-up period. Only 31% of children were referred to a specialist for additional evaluation. CONCLUSIONS: High rates of ASD-specific screening do not necessarily translate to increases in subsequent referrals for ASD evaluation or ASD diagnoses. Low rates of referrals and/or lack of follow-through on referrals appear to contribute to delays in children's receipt of ASD diagnoses. Additional education of primary care providers regarding the referral process after a failed ASD screening is warranted.

RESUMO

Although Aurora A, B, and C kinases share high sequence similarity, especially within the kinase domain, they function distinctly in cell-cycle progression. Aurora A depletion primarily leads to mitotic spindle formation defects and consequently prometaphase arrest, whereas Aurora B/C inactivation primarily induces polyploidy from cytokinesis failure. Aurora B/C inactivation phenotypes are also epistatic to those of Aurora A, such that the concomitant inactivation of Aurora A and B, or all Aurora isoforms by nonisoform-selective Aurora inhibitors, demonstrates the Aurora B/C-dominant cytokinesis failure and polyploidy phenotypes. Several Aurora inhibitors are in clinical trials for T/B-cell lymphoma, multiple myeloma, leukemia, lung, and breast cancers. Here, we describe an Aurora A-selective inhibitor, LY3295668, which potently inhibits Aurora autophosphorylation and its kinase activity in vitro and in vivo, persistently arrests cancer cells in mitosis, and induces more profound apoptosis than Aurora B or Aurora A/B dual inhibitors without Aurora B inhibition-associated cytokinesis failure and aneuploidy. LY3295668 inhibits the growth of a broad panel of cancer cell lines, including small-cell lung and breast cancer cells. It demonstrates significant efficacy in small-cell lung cancer xenograft and patient-derived tumor preclinical models as a single agent and in combination with standard-of-care agents. LY3295668, as a highly Aurora A-selective inhibitor, may represent a preferred approach to the current pan-Aurora inhibitors as a cancer therapeutic agent.
