Roles of pediatric surgeons in palliative pediatric oncology.

Pediatric surgeons engaged in oncology will inevitably treat patients receiving palliative care, but their role in this context is poorly described. This article identifies some of the challenges and opportunities of surgical involvement in pediatric oncology palliative care, underscoring how the surgeon's expertise can be exploited to significantly benefit children with cancer. Specific examples of skills (procedural, communication, and coordination) that surgeons can provide to the multidisciplinary palliative care teams are described and the importance of collaboration is highlighted.

Anti-amyloid treatment is broadly effective in neuronopathic mucopolysaccharidoses and synergizes with gene therapy in MPS-IIIA.

Mucopolysaccharidoses (MPSs) are childhood diseases caused by inherited deficiencies in glycosaminoglycan degradation. Most MPSs involve neurodegeneration, which to date is untreatable. Currently, most therapeutic strategies aim at correcting the primary genetic defect.

Erasure of DNA methylation in rat fetal germ cells is sex-specific and sensitive to maternal high-fat diet.

In mammals, DNA methylation (DNAme) erasure and reinstatement during embryo development and germline establishment are sensitive to the intrauterine environment. Maternal intake of a high-fat diet (HFD), associated with excessive gestational weight gain, has transgenerational effects on offspring health, which may be mediated by changes in DNAme in the germline. Here, we tested the impact of a maternal HFD on embryonic germline DNAme erasure using a rat strain that expresses green fluorescent protein specifically in germ cells.

Toward Physiological Detection of a "Just-Right" Challenge Level for Motor Learning in Immersive Virtual Reality: Protocol for a Cross-Sectional Study.

Background: Motor learning, a primary goal of pediatric rehabilitation, is facilitated when tasks are presented at a "just-right" challenge level-at the edge of the child's current abilities, yet attainable enough to motivate the child in persistent efforts for success. Immersive virtual reality (VR) may be ideally suited for "just-right" task challenges because it enables precise adjustments of task parameters in motivating environments. Rehabilitation-specific VR tasks often use dynamic difficulty algorithms based on task performance to personalize task difficulty.

Adiposity and cardiac autonomic function in children with a family history of obesity.

Purpose: Data on associations between adiposity and heart rate variability (HRV) in prepubertal children are limited. We examined the associations between adiposity indices and HRV, independent of lifestyle behaviors, comparing multiple indicators of adiposity, and explored differences between boys and girls.

Methods: Data stem from 469 participants of the QUALITY cohort (630 children aged 8-10 years with a parental history of obesity).

Management of anaphylaxis after pre-hospital epinephrine use in children with food-induced anaphylaxis.

Background: Previous guidelines recommend prompt epinephrine administration, followed by observation in the emergency department (ED). The need for transfer in all cases of anaphylaxis has recently been challenged.

Objective: To evaluate the need for additional ED treatment among children with anaphylaxis who received prehospital epinephrine.

Resting-state alterations in emotion salience and default-mode network connectivity in atypical trajectories of psychotic-like experiences.

Social cognition is commonly altered in people with psychosis. Two main brain networks have been implicated: the default-mode network (DMN), which is associated with socio-cognitive processing, and the salience network (SN) associated with socio-affective processing. Disturbances to the resting-state functional connectivity of these networks have been identified in schizophrenia and high-risk individuals, but there have been no studies in adolescents displaying distinct trajectories of subclinical psychotic-like experiences (PLEs).

Regional patterns of human cortex development correlate with underlying neurobiology.

Human brain morphology undergoes complex changes over the lifespan. Despite recent progress in tracking brain development via normative models, current knowledge of underlying biological mechanisms is highly limited. We demonstrate that human cortical thickness development and aging trajectories unfold along patterns of molecular and cellular brain organization, traceable from population-level to individual developmental trajectories.

Vancomycin in Pediatric Patients with Cystic Fibrosis: Dose Optimization Using Population Pharmacokinetic Approach.

Background: An increase in Staphylococcus aureus infections has been reported in pediatric patients with cystic fibrosis (CF) over the last few years. This pathogen is commonly treated with vancomycin, an antibiotic for which therapeutic drug monitoring (TDM) is recommended. Updated guidelines were recently published regarding new targets of exposure for the TDM of vancomycin through a Bayesian approach, using population pharmacokinetic (popPK) models.

The innate immune regulator MyD88 dampens fibrosis during zebrafish heart regeneration.

The innate immune response is triggered rapidly after injury and its spatiotemporal dynamics are critical for regeneration; however, many questions remain about its exact role. Here we show that MyD88, a key component of the innate immune response, controls not only the inflammatory but also the fibrotic response during zebrafish cardiac regeneration. We find in cryoinjured myd88 ventricles a significant reduction in neutrophil and macrophage numbers and the expansion of a collagen-rich endocardial population.

Myopic Shift over 5 Years after Pediatric Lensectomy with Primary Intraocular Lens Implantation.

Purpose: To report the change in refractive error over 5 years after primary intraocular lens (IOL) placement by age at surgery and to identify factors associated with the change in refractive error after 5 years.

Design: Prospective observational study at 61 pediatric eye care practices.

Participants: One hundred eighty-six eyes of 152 children undergoing primary IOL implantation before 13 years of age for nontraumatic cataract.

Immune landscape of oncohistone-mutant gliomas reveals diverse myeloid populations and tumor-promoting function.

Histone H3-mutant gliomas are deadly brain tumors characterized by a dysregulated epigenome and stalled differentiation. In contrast to the extensive datasets available on tumor cells, limited information exists on their tumor microenvironment (TME), particularly the immune infiltrate. Here, we characterize the immune TME of H3.

Integrative genetic analysis: cornerstone of precision psychiatry.

The role of genetic testing in the domain of neurodevelopmental and psychiatric disorders (NPDs) is gradually changing from providing etiological explanation for the presence of NPD phenotypes to also identifying young individuals at high risk of developing NPDs before their clinical manifestation. In clinical practice, the latter implies a shift towards the availability of individual genetic information predicting a certain liability to develop an NPD (e.g.

Intranasal midazolam for procedural distress in children in the emergency department: a systematic review and meta-analysis.

Objectives: Intranasal (IN) midazolam is the most common anxiolytic for children in the emergency department (ED), but evidence of benefit is conflicting. We synthesized the evidence on IN midazolam for procedural distress in children undergoing ED painful procedures.

Methods: We included trials involving painful ED procedures in children 0-18 years involving IN midazolam.

Evaluation of the decision-making process underlying the initial off-label use of vaccines: A scoping review.

Background: This scoping review aimed to assess the non-standardized decision-making process of National or International Immunization Technical Advisory Groups (NITAG) in developing novel off-label recommendations by examining the supportive evidence.

Methods: We used the Joanna Briggs Institute framework. A search strategy was developed with a librarian to identify recommendations and evidence from peer-reviewed and gray literature until January 2022, using PubMed, Medline, EMBASE, clinicaltrials.

The association between depressive symptoms and overweight or obesity in prepubertal children: Findings from the QUALITY cohort.

Background: Youth obesity and depression are public health concerns. Although meta-analyses suggest a positive association between those conditions in adults and adolescents, evidence remains unclear in prepubertal children. We examined the bidirectional associations between levels of depressive symptoms and weight status in 8-10-year-old children with a parental history of obesity, over two years, and whether they differ by sex.
