    Abstract H3.3 is a highly conserved nonreplicative histone variant. H3.3 is enriched in promoters and enhancers of active genes, but it is also found within suppressed heterochromatin, mostly around telomeres. Accordingly, H3.3 is associated with seemingly contradicting functions: It is involved in development, differentiation, reprogramming, and cell fate, as well as in heterochromatin formation and maintenance, and the silencing of developmental genes. The emerging view is that different cellular contexts and histone modifications can promote opposing functions for H3.3. Here, we aim to provide an update with a focus on H3.3 functions in early mammalian development, considering the context of embryonic stem cell maintenance and differentiation, to finally conclude with emerging roles in cancer development and cell fate transition and maintenance.

    Abstract Background: Outcome measures are extensively used within human physiotherapy, but a widely accepted issue in veterinary physiotherapy is that outcome measures lack sufficient evaluation and standardisation in terms of how they are implemented. This cross-sectional study aimed to provide clarity on (1) the current selection of outcome measures in canine and equine physiotherapy and (2) investigate external influences on outcome measure selection, including comparative literature availability, professional memberships and background.
    Methods: A structured scoping literature review consolidated current understanding and limitations. This informed a survey of qualified veterinary physiotherapists (n = 40). The statistical analysis comprised descriptive statistics.
    Results: Key observations included (1) a lack of difference in outcome measure application between veterinary physiotherapists with and without a human physiotherapy background, (2) enhanced outcome measure utilisation by registry body members and (3) an overall skew towards subjective, rather than objective, outcome measure use.
    Limitations: The study was limited by the absence of a defined veterinary physiotherapist population and subsequent convenience sample size.
    Conclusion: The apparent skew towards subjective outcome measures highlights objective outcome measure underutilisation and the need for a more extensive evidence base. In conclusion, there is a need to develop comprehensive professional development resources promoting the use of repeatable outcome measures such as goniometers and the Liverpool osteoarthritis scoring.

    Abstract Background: Depressive moods and behaviors are developmentally normative, yet potentially impairing, in preschool-aged children. In addition to frequency, duration of behavior is an important parameter to consider when characterizing risk for worsening mood dysregulation. The goal of this study was to identify the duration and severity of depressive moods and behaviors and associations with impairment in a large community sample of preschool-aged children using an online parent-report daily diary.
    Methods: Primary caregivers (N = 900) of 3-5-year-old children reported the daily duration of each instance of seven depressive moods and behaviors for 14 days. We used item response theory analyses to examine duration item characteristics.
    Results: Moods and behaviors occurred at specific durations to be considered psychometrically severe/rare; for example, instances of sadness had to last an average total of 32 min per day or more, irritability at least 38 min, tantrums at least 30 min, and tearfulness/sensitivity at least 35 min. Longer durations of mood and behavior were associated with daily impairment, as well as older child age and less parental education.
    Conclusions: To our knowledge, this is the first study to delineate specific duration ranges for depressive moods and behaviors in preschool-aged children. These data, coupled with information about the frequency of mood-related behaviors, can assist child practitioners in differentiating normative patterns from less normative mood problems to evaluate which children may be at risk. Future work should identify the duration of depressive moods and behaviors in early childhood that predict clinically significant psychopathology over time.

    Abstract Parents of sexual and gender minority (SGM) youth play an important role in supporting their SGM child's mental health in the face of stigma. Yet, parents of SGM youth may themselves experience stigma, including discrimination/rejection, and its emotional consequences, including vicarious stigma and shame. The present cross-sectional study leveraged a national sample of parents of SGM youth to investigate associations between parents' stigma experiences and self-reported anxiety and depression symptoms. Further, we additionally explored sociodemographic and contextual correlates of parents' stigma experiences. Participants included 264 parents (

    Abstract Pediatric liver transplant recipients are a high-risk group for the development of adenovirus hepatitis and other manifestations of disseminated adenoviral disease. The risk is greatest during periods of increased immunosuppression, including immediately post-transplantation and following treatment for rejection. Manifestations of adenovirus hepatitis are heterogeneous with a wide spectrum of clinical severity, ranging from mild, focal disease to fulminant liver failure. Here we report a case of liver transplantation-associated adenovirus hepatitis presenting with fever and multifocal liver lesions. The diagnosis was not clinically suspected due to atypical imaging findings and pathology. Non-targeted metagenomic sequencing of plasma cell-free DNA facilitated and expedited the diagnosis. Confirmatory conventional testing was obtained, allowing for appropriate initiation of targeted treatment in this patient.

    Abstract Background: Irritability, marked by diminished frustration tolerance, holds significant implications for youth mental health treatment. Despite prior research on irritability trajectories, understanding of individual differences during adolescence remains limited. This study examines the stability and trajectory of irritability across ages 12-18, investigating associations with psychopathology and functioning at age 18.
    Methods: A community sample of families with 3-year-old children (N = 518) was recruited via commercial mailing lists. Irritability was assessed at ages 12, 15, and 18 using the Affective Reactivity Index. Psychopathology at age 18 was evaluated with the Kiddie Schedule for Affective Disorders and Schizophrenia, and functioning was assessed through the UCLA Life Stress Interview. Measurement invariance analyses and latent growth curve modeling were conducted within a structural equation modeling (SEM) framework.
    Results: Configural, metric, and scalar invariance models were supported. Elevated irritability at age 12 predicted adverse outcomes at age 18, including increased psychotropic medication use, mental health treatment, suicidal ideation, self-injury, and psychiatric disorders. Importantly, these associations persisted even after accounting for corresponding variables at age 12. The trajectory of irritability during early adolescence significantly predicted heightened risks for various outcomes at age 18, including suicidal ideation, depression, anxiety, disruptive behavior disorders, and impaired interpersonal functioning.
    Discussion: Limitations include using only youth-reported data at age 18, limited generalizability from a mostly White, middle-class sample, and insufficient exploration of the broader developmental trajectory of irritability. Nevertheless, the findings emphasize the crucial role of irritability's trajectory in influencing various psychopathological and functional outcomes in late adolescence.

    Abstract Background: Gestational exposure to environmental chemicals (ECs) is associated with adverse, sex-specific offspring health effects of global concern. As the maternal steroid, cytokine and oxidative stress milieus can have critical effects on pregnancy outcomes and the programming of diseases in offspring, it is important to study the impact of real-life EC exposure, i.e., chronic low levels of mixtures of ECs on these milieus. Sheep exposed to biosolids, derived from human waste, is an impactful model representing the ECs humans are exposed to in real-life. Offspring of sheep grazed on biosolids-treated pasture are characterized by reproductive and metabolic disruptions.
    Objective: To determine if biosolids exposure disrupts the maternal steroid, cytokine and oxidative stress milieus, in a fetal sex-specific manner.
    Methods: Ewes were maintained before mating and through gestation on pastures fertilized with biosolids (BTP), or inorganic fertilizer (Control). From maternal plasma collected mid-gestation, 19 steroids, 14 cytokines, 6 oxidative stress markers were quantified. Unpaired t-test and ANOVA were used to test for differences between control and BTP groups (n = 15/group) and between groups based on fetal sex, respectively. Correlation between the different markers was assessed by Spearman correlation.
    Results: Concentrations of the mineralocorticoids - deoxycorticosterone, corticosterone, the glucocorticoids - deoxycortisol, cortisol, cortisone, the sex steroids - androstenedione, dehydroepiandrosterone, 16-OH-progesterone and reactive oxygen metabolites were higher in the BTP ewes compared to Controls, while the proinflammatory cytokines IL-1β and IL-17A and anti-inflammatory IL-36RA were decreased in the BTP group. BTP ewes with a female fetus had lower levels of IP-10.
    Discussion: These findings suggest that pre-conceptional and gestational exposure to ECs in biosolids increases steroids, reactive oxygen metabolites and disrupts cytokines in maternal circulation, likely contributors to the aberrant phenotypic outcomes seen in offspring of BTP sheep - a translationally relevant precocial model.
