    Abstract Objective: To assess discharge readiness and clinical engagement post-discharge in families of children undergoing congenital heart surgery.
    Study design: This prospective cross-sectional study was performed at a major tertiary pediatric cardiac referral center. Eligible parents and caregivers completed a discharge readiness tool, the Readiness for Hospital Discharge Scale for Parents of Hospitalized Children, via online survey on the day of discharge. Clinical engagement data included subsequent phone calls, clinic visits, emergency department visits, and hospital readmissions. Readiness for Hospital Discharge Scale for Parents of Hospitalized Children scores were measured as follows: very high (9-10), high (8-8.9), moderate (7-7.9), and low (<7). Descriptive statistics were used to describe demographic data.
    Results: In total, 128 families enrolled between April and December 2021. Parent discharge readiness scores ranged from "high" to "very high." Families with lower socioeconomic status and younger patients (especially single-ventricle infants or "interstage") had a greater proportion of clinic visits, emergency department visits, and hospital readmissions within 30-days postdischarge compared with other groups.
    Conclusions: Discharge readiness scores were not associated with clinical engagement. We identified vulnerable populations as evidenced by a greater frequency of clinical engagement in the immediate postoperative period, particularly younger patients and first-time surgeries. Although these visits may be appropriate, novel programs could enhance education and emotional support to prevent delay in seeking care or creating excessive stress and anxiety after discharge.

    Abstract Background: The use of technology is an increasingly common practice among preschoolers. Little is known about the relationship between screen time exposure (STE) and aspects related to family and the environment.
    Aim: The aim is to characterize STE in Brazilian children aged between 3 and 5 years. Furthermore, the objective of this study is to associate the STE of children and of their parents with sociodemographic variables.
    Methods: Children aged between 3 and 5 years from southern Brazil and their parents participated in this study. To investigate STE, the researchers developed a specific questionnaire. To compare STE between age groups, the Kruskal-Wallis test was performed, followed by Dunn's post hoc test. Spearman's correlation and linear regression were used to correlate the variables.
    Results: Children (n = 237) spend an average of 3.7 ± 0.8 h/day in front of screens. The STE of children had a moderately positive correlation with the STE of their parents (r = 0.4; p-value < 0.001). Only the variables of the children's and parents' STE had a significant and positive association. The model is significant (F = 6164, p-value < 0.001) and the residuals of the model met the necessary assumptions, with normal distribution, constant variance and without the presence of outliers.
    Conclusion: Children in southern Brazil remain in front of screens four times longer than the recommended amount of time. It was also found that the STE of parents directly influences that of their children.

    Abstract The rapidly acting antidepressants ketamine and scopolamine exert behavioral effects that can last from several days to more than a week in some patients. The molecular mechanisms underlying the maintenance of these antidepressant effects are unknown. Here we show that methyl-CpG-binding protein 2 (MeCP2) phosphorylation at Ser421 (pMeCP2) is essential for the sustained, but not the rapid, antidepressant effects of ketamine and scopolamine in mice. Our results reveal that pMeCP2 is downstream of BDNF, a critical factor in ketamine and scopolamine antidepressant action. In addition, we show that pMeCP2 is required for the long-term regulation of synaptic strength after ketamine or scopolamine administration. These results demonstrate that pMeCP2 and associated synaptic plasticity are essential determinants of sustained antidepressant effects.

    Abstract Identifying genes linked to extreme phenotypes in humans has the potential to highlight biological processes not shared with all other mammals. Here, we report the identification of homozygous loss-of-function variants in the primate-specific gene ZNF808 as a cause of pancreatic agenesis. ZNF808 is a member of the KRAB zinc finger protein family, a large and rapidly evolving group of epigenetic silencers which target transposable elements. We show that loss of ZNF808 in vitro results in aberrant activation of regulatory potential contained in the primate-specific transposable elements it represses during early pancreas development. This leads to inappropriate specification of cell fate with induction of genes associated with liver identity. Our results highlight the essential role of ZNF808 in pancreatic development in humans and the contribution of primate-specific regions of the human genome to congenital developmental disease.

    Abstract Enhancer redundancy has been postulated to provide a buffer for gene expression against genetic and environmental perturbations. While work in Drosophila has identified functionally overlapping enhancers, work in mammalian models has been limited. Recently, we have identified two partially redundant enhancers, nPE1 and nPE2, that drive proopiomelanocortin gene expression in the hypothalamus. Here we demonstrate that deletion of nPE1 produces mild obesity while knockout of nPE2 has no discernible metabolic phenotypes. Additionally, we show that acute leptin administration has significant effects on nPE1 knockout mice, with food intake and body weight change significantly impacted by peripheral leptin treatment. nPE1 knockout mice became less responsive to leptin treatment over time as percent body weight change increased over 2 week exposure to peripheral leptin. Both Pomc and Agrp mRNA were not differentially affected by chronic leptin treatment however we did see a decrease in Pomc and Agrp mRNA in both nPE1 and nPE2 knockout calorie restricted mice as compared to calorie restricted PBS-treated WT mice. Collectively, these data suggest dynamic regulation of Pomc by nPE1 such that mice with nPE1 knockout become less responsive to the anorectic effects of leptin treatment over time. Our results also support our earlier findings in which nPE2 may only be critical in adult mice that lack nPE1, indicating that these neural enhancers work synergistically to influence metabolism.

    Abstract Although the oncolytic parvovirus H-1PV has entered clinical trials, predicting therapeutic success remains challenging. We investigated whether the antiviral state in tumor cells determines the parvoviral oncolytic efficacy. The interferon/interferon-stimulated genes (IFN/ISG)-circuit and its major configurator, human endogenous retroviruses (HERVs), were evaluated using qRT-PCR, ELISA, Western blot, and RNA-Seq techniques. In pancreatic cancer cell lines, H-1PV caused a late global shutdown of innate immunity, whereby the concomitant inhibition of HERVs and IFN/ISGs was co-regulatory rather than causative. The growth-inhibitory IC50 doses correlated with the power of suppression but not with absolute ISG levels. Moreover, H-1PV was not sensitive to exogenous IFN despite upregulated antiviral ISGs. Such resistance questioned the biological necessity of the oncotropic ISG-shutdown, which instead might represent a surrogate marker for personalized oncolytic efficacy. The disabled antiviral homeostasis may modify the activity of other viruses, as demonstrated by the reemergence of endogenous AluY-retrotransposons. This way of suppression may compromise the interferogenicity of drugs having gemcitabine-like mechanisms of action. This shortcoming in immunogenic cell death induction is however amendable by immune cells which release IFN in response to H-1PV.

    Abstract Obesity is a complex disease that is the result of a number of different factors including genetic, environmental, and endocrine abnormalities. Given that monogenic forms of obesity are rare, it is important to identify other mechanisms that contribute to its etiology. Methyl-Cp-G binding protein 2 (MeCP2) is a neuroepigenetic factor that binds to methylated regions of DNA to influence transcription. Past studies demonstrate that disruption in MeCP2 function produces obesity in mice. Using a diet-induced obesity mouse model, we show that perinatal exposure to high fat diet significantly decreases MeCP2 protein expression in the hypothalamus of female mice, effects not seen when high fat diet is given to mice during adulthood. Moreover, these effects are seen specifically in a subregion of the hypothalamus known as the arcuate nucleus with females having decreased MeCP2 expression in rostral areas and males having decreased MeCP2 expression in intermediate regions of the arcuate nucleus. Interestingly, mice gain more weight when exposed to high fat diet during adulthood relative to mice exposed to high fat diet perinatally, suggesting that perhaps high fat diet exposure during adulthood may be affecting mechanisms independent of MeCP2 function. Collectively, our data demonstrate that there are developmentally sensitive periods in which MeCP2 expression is influenced by high fat diet exposure and this occurs in a sexually dimorphic manner.

    Abstract DNA methylation has been shown to impact certain forms of synaptic and behavioral plasticity that have been implicated in the development in psychiatric disorders. DNA methylation is catalyzed by DNA methyltransferase (DNMT) enzymes that continue to be expressed in postmitotic neurons in the forebrain. Using a conditional forebrain knockout of DNMT1 or DNMT3a we assessed the role of these DNMTs in anxiety and depressive-like behavior in mice using an array of behavioral testing paradigms. Forebrain deletion of DNMT1 had anxiolytic and antidepressant-like properties as assessed by elevated plus maze, novelty suppressed feeding, forced swim, and social interaction tests. DNMT3a knockout mice, by contrast, did not exhibit significant behavioral alterations in these tests. Given the putative role of altered DNA methylation patterns in the development of schizophrenia, we also assessed DNMT1 and DNMT3a knockout mice in a prepulse inhibition task and found an enhanced prepulse inhibition of startle in DNMT1 knockouts relative to wild type mice, with no change evident in DNMT3a knockout mice. Our data suggest that DNMT1 and DNMT3a are distinctly involved in affective behavior and that DNMT1 may ultimately represent a potential target for treatment of certain affective behavioral disorders.
