Comparison of Pediatric and Adult Firearm Deaths to Inform Violence Prevention at Pediatric Trauma Centers.

Introduction: Hospital-based violence intervention programs primarily target adults, raising questions about the effectiveness in preventing pediatric firearm deaths. We hypothesized that pediatric and adult firearm injury deaths are different enough to require unique intervention strategies.

Methods: Retrospective chart review was conducted of medical examiner and trauma center records of firearm-related deaths in the largest metropolitan county in Texas.

Decreased Association Between Patellar Axial Malalignment and Patellar Height and Increased Association Between Patellar Axial Malalignment and Tibial Tubercle-Trochlear Groove During Weightbearing.

Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.

Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?

Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.

REVEAL-CP: Selective Screening of Pediatric Patients for Aromatic L-Amino Acid Decarboxylase Deficiency with a Guthrie Card and Structural Modeling of One Index Case.

The main objective of this prospective, multicenter study (REVEAL-CP) was to test children with cerebral palsy-like signs and symptoms for raised 3--methyldopa (3-OMD) blood levels, a biomarker for aromatic L-amino acid decarboxylase deficiency (AADCd). A secondary objective was to characterize the molecular basis for the defective aromatic L-amino acid decarboxylase (AADC) gene product. Patients were identified in pediatric secondary and tertiary care hospitals through database searches and personal communication.

Pediatric relapsed/refractory ALK+ anaplastic large cell lymphoma treatment and outcomes in the targeted drug era.

Treatment options for patients with relapsed or refractory (R/R) anaplastic large cell lymphoma (ALCL) have increased in the era of targeted therapies such as brentuximab vedotin (BV) and Anaplastic Lymphoma Kinase (ALK) inhibitors. However, there is no standard treatment and limited published data evaluating their use. The goal of this retrospective study is to describe current real-world treatment and outcomes of pediatric, adolescent, and young adult patients with R/R ALK-positive ALCL.

Examining Concurrent Associations Between Gesture Use, Developmental Domains, and Autistic Traits in Toddlers With Down Syndrome.

Purpose: Toddlers with Down syndrome (DS) showcase comparable or higher rates of gestures than chronological age- and language-matched toddlers without DS. Little is known about how gesture use in toddlers with DS relates to multiple domains of development, including motor, pragmatics, language, and visual reception (VR) skills. Unexplored is whether gesture use is a good marker of social communication skills in DS or if gesture development might be more reliably a marker of motor, language, pragmatics, or VR skills.

WWC proteins-mediated compensatory mechanism restricts schwannomatosis driven by loss of function.

NF2-related schwannomatosis, previously known as neurofibromatosis type 2, is a genetic disorder characterized by nerve tumors due to gene mutations. Mice with deletion develop schwannomas slowly with low penetrance, hence inconvenient for preclinical studies. Here, we show that NF2, by recruiting E3 ubiquitin ligases β-TrCP1/2, promotes WWC1-3 ubiquitination and degradation.

Elucidating assembly and function of VirB8 cell wall subunits refines the DNA translocation model in Gram-positive T4SSs.

Bacterial type IV secretion systems (T4SSs) are widespread nanomachines specialized in the transport across the cell envelope of various types of molecules including mobile genetic elements during conjugation. Despite their prevalence in Gram-positive bacteria, including relevant pathogens, their assembly and functioning remain unknown. This study addresses these gaps by investigating VirB8 proteins, known to be central components of conjugative T4SSs in Gram-positive bacteria.

Do We Need a Fluid Bolus? The Necessary Refinement of Pediatric Propofol Sedation - a Quality Improvement Project.

Background: Propofol is commonly used for pediatric MRIs to minimize patient movement. At our institution, intensivists typically administer a prophylactic 20 ml/kg saline bolus to maintain blood pressure (BP) during propofol sedation. This quality improvement project assessed whether a 10 ml/kg and a completely eliminated saline bolus are as effective as the standard 20 ml/kg bolus in completing pediatric propofol sedation and maintaining Mean Arterial Pressure (MAP).

Diagnostic properties of differing BP thresholds for adverse pregnancy outcomes in standard-risk nulliparous women: A secondary analysis of SCOPE cohort data.

Background: In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered blood pressure (BP) thresholds to define hypertension in adults outside pregnancy. If used in pregnancy, these lower thresholds may identify women at increased risk of adverse outcomes, which would be particularly useful to risk-stratify nulliparous women. In this secondary analysis of the SCOPE cohort, we asked whether, among standard-risk nulliparous women, the ACC/AHA BP categories could identify women at increased risk for adverse outcomes.

Respiratory virus detections in children presenting to an Australian paediatric referral hospital pre-COVID-19 pandemic, January 2014 to December 2019.

Acute respiratory infections cause significant paediatric morbidity, but for pathogens other than influenza, respiratory syncytial virus (RSV), and SARS-CoV-2, systematic monitoring is not commonly performed. This retrospective analysis of six years of routinely collected respiratory pathogen multiplex PCR testing at a major paediatric hospital in New South Wales Australia, describes the epidemiology, year-round seasonality, and co-detection patterns of 15 viral respiratory pathogens. 32,599 respiratory samples from children aged under 16 years were analysed.

The Kinesin Kar3 is Required for Endoplasmic Reticulum-Associated Degradation.

Degradation of aberrant, excess, and regulatory proteins at the endoplasmic reticulum (ER) is a conserved feature of eukaryotic cells, disruption of which contributes to disease. While remarkable progress has been made in recent years, mechanisms and genetic requirements for ER-Associated Degradation (ERAD) remain incompletely understood. We recently conducted a screen for genes required for turnover of a model ER translocon-associated substrate of the Hrd1 ubiquitin ligase in .

GATA2 links stemness to chemotherapy resistance in acute myeloid leukemia.

Stemness-associated cell states are linked to chemotherapy resistance in AML. We uncovered a direct mechanistic link between expression of the stem cell transcription factor GATA2 and drug resistance. The GATA-binding protein 2 (GATA2) plays a central role in blood stem cell generation and maintenance.

The Transition to Kindergarten for Hispanic and Latine Autistic Children: A Focus Group Study with Caregivers.

Purpose: Past research highlights the different facilitators and barriers that caregivers of children on the autism spectrum experience during the transition to kindergarten and when navigating special education services. Caregivers who identify as Hispanic and/or Latine may face distinct challenges during this process, such as language differences, differences in understanding autism and special education, and barriers to advocating for their child. Hispanic and Latine caregivers also have strengths, resources, and strategies (i.

Hair Cortisol in Young Children with Autism and Their Parents: Associations with Child Mental Health, Eating Behavior and Weight Status.

Children with autism and their parents face daily challenges that may be stressful for both. However, little is known about biological stress (hair cortisol concentrations [HCC]) in these families and its connection to children's health outcomes. This study investigates biological stress in children with autism and their parents and its associations with child mental health, eating behavior and BMI.

Boosting the catalytic efficiency of UGT51 for efficient production of rare ginsenoside Rh2.

Ginsenoside Rh2(S) is well-known for its therapeutic potential against diverse conditions, including some cancers, inflammation, and diabetes. The enzymatic activity of uridine diphosphate glycosyltransferase 51 (UGT51) from Saccharomyces cerevisiae plays a pivotal role in the glycosylation process between UDP-glucose (donor) and protopanaxadiol (acceptor), to form ginsenoside Rh2. However, the catalytic efficiency of the UGT51 has remained a challenging task.

Improving Therapeutic Adherence and Reducing Therapeutic Inertia in the Management of People with Cardiometabolic Diseases: A Call-to-Action from the Middle East.

Hypertension, dyslipidemia, and type 2 diabetes are highly prevalent and poorly controlled cardiometabolic diseases in the Middle East. Therapeutic non-adherence and therapeutic inertia are major contributors to this suboptimal disease control. Regardless of the cardiometabolic disease, evidence-based solutions may be used to improve therapeutic non-adherence and overcome inertia, and thereby help to alleviate the heavy burden of cardiovascular disease in the Middle East.

Bracing effectiveness in idiopathic early onset scoliosis followed to skeletal maturity: a systematic review and meta-analysis.

Purpose: Treating idiopathic Early Onset Scoliosis (idiopathic EOS) is challenging due to ongoing growth and extensive follow-ups. While bracing is effective for Adolescent Idiopathic Scoliosis (AIS), its value for children under 10 remains debated. This systematic review and meta-analysis evaluates the effectiveness of spinal bracing in idiopathic EOS, followed to skeletal maturity.

The association of congenital diaphragmatic hernia with scoliosis.

Purpose: To determine the prevalence of scoliosis in patients who have undergone surgical repair of CDH and attempt to assess the aetiology of scoliosis in affected cases.

Methods: A prospectively collected database of patients with CDH treated in a single centre between 1997 and 2023 was reviewed. Cases with adequate records who continued to reside locally having survived beyond age 2 and > 2 years following CDH repair were included.

Perception of Quality of Life by Primary Caregivers of Children with Congenital Zika Syndrome: a Cross-Sectional Study.

Objective: The study aimed to evaluate the quality of life (QoL) of caregivers of children diagnosed with CZS and to assess the association of findings with socioeconomic and CZS-associated variables.

Methods: This was a cross-sectional, quantitative study, carried out over three days of multidisciplinary care for patients with CZS. Sixty-four participants underwent a quality of life assessment using the World Health Organization Quality of Life questionnaire (WHOQOL-BREF) in Portuguese.

Primary diffuse leptomeningeal atypical teratoid/rhabdoid tumours (ATRT) of childhood: a molecularly characterised case report and literature review.

Background: Atypical teratoid/rhabdoid tumours (ATRTs) are malignant central nervous system tumours, typically presenting in the posterior fossa of very young children. Prognosis remains poor despite current therapy, while tumorigenesis implicates both genomic and epigenetic dysregulation. Primary diffuse leptomeningeal (PDL) ATRT, characterised by the absence of an intraparenchymal mass lesion, is seldom reported but appears associated with a dismal outcome.

The publication fate of abstracts awarded prizes at European Society of Paediatric Radiology annual scientific meetings.

Background: The European Society of Paediatric Radiology (ESPR) awards prizes for outstanding work presented at their annual scientific meetings. The proportion of ESPR prize-winning abstracts to journal publications is not known. Contextualising abstract-to-publication proportions by evaluating publication experience can yield valuable insights and actionable outcomes to support researchers in overcoming barriers to journal publication.
