An examination of the effect of area-level characteristics on juvenile justice and child welfare referrals using multivariate Bayesian spatial modeling.

Background: Neighborhood disadvantage is linked to a higher risk of referrals to child welfare and juvenile justice systems. While past research has explored these associations independently, no study has concurrently examined the spatial overlap of child maltreatment and juvenile justice involvement.

Objective: We examine the spatial overlap of involvement in juvenile justice and child welfare systems to identify areas of shared risk.

Factors associated with caregiver strain among mothers and fathers of children with advanced cancer.

Objectives: To characterize caregiver experiences in the context of advanced pediatric cancer by identifying individual (i.e., demographic factors, stress) and family context factors (i.

Depression and anxiety in transgender and non-binary adolescents: prevalence and associations between adolescent and caregiver reports.

Unlabelled: Transgender/non-binary (TNB) adolescents are at increased risk for mental health concerns, and caregiver awareness is important to facilitate access to care. Yet, limited research has examined caregiver awareness of TNB mental health. Thus, we examined (1) the prevalence of internalizing symptoms (depression, generalized anxiety, separation anxiety, social anxiety) among TNB adolescents and (2) associations between adolescent and caregiver reports of adolescent mental health symptoms.

The seasonal distribution of immune thrombotic thrombocytopenic purpura is influenced by geography: Epidemiologic findings from a multi-center analysis of 719 disease episodes.

Prior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5-year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included.

Comparability of Beckman Coulter Cardiac Troponin I Assays.

Objective: Cardiac troponin I (cTnI) is one of the most sensitive and specific biomarkers of myocardial injury. The rise and/or fall of cardiac troponins above the 99th percentile of the upper reference limit (URL) is required in the assessment of acute myocardial infarction.

Methods: We analyzed the variation between the Beckman Coulter contemporary cTnI AccuTnI+3 assay and high sensitivity cTnI (hs-cTnI) assay tested on DXI 800 using 424 patient specimens with troponin levels ranging from 0-16754 ng/L.

A Multilevel Analysis of Individual and Community Factors Associated With Case Dispositions Following Child Maltreatment Investigations.

Understanding service disposition pathways is critical to provide deeper insight into why certain subgroups of the population are at risk for recurrent Child Protective Services (CPS) involvement and may highlight disparities across groups or geographic areas. Using the Decision-Making Ecology Framework as a lens, the present study examines whether service disposition pathways are influenced by risk assessment, safety concerns, child age, maltreatment type, previous CPS involvement, and/or county-level structural vulnerability. We linked administrative data from New Mexico's Department of Children, Youth and Families (DCYF) to data from the American Community Survey.

Using the consolidated framework for implementation research to identify challenges and opportunities for implementing a reproductive health education program into sickle cell disease care.

Background: As survival rates for individuals with sickle cell disease (SCD) increase, calls have been made to improve their reproductive healthcare and outcomes. The research team created a web-based program entitled Fertility edUcaTion to Understand ReproductivE health in Sickle cell disease (FUTURES). The study aim was to use the Consolidated Framework for Implementation Research (CFIR) during pre-implementation to identify challenges and opportunities from the individual to systems level of implementation to ultimately optimize the integration of FUTURES into clinical practice.

Experiences and outcomes of fertility testing in male adolescents with sickle cell disease.

Adult males with sickle cell disease (SCD) may have abnormal semen parameters, raising the concern that SCD and/or treatments may impact fertility. Yet, studies that include adolescents are lacking. To determine if fertility testing is feasible in male adolescents with SCD, and to explore their experiences and outcomes of fertility testing, 33 adolescents who completed a web-based SCD reproductive health education program were offered a free semen analysis.

Primary care use and depression screening among young adults with sickle cell disease during their final year of pediatric hematology care.

Depression may contribute to transition risk among young adults with sickle cell disease (SCD). It is unclear if they receive depression screening because primary care providers (PCPs) routinely perform this screening, but PCP use declines with age. This retrospective study of young adults with SCD during their final year of pediatric hematology care identified 51 (91%) had PCPs.

Improving medication adherence monitoring and clinical outcomes through mHealth: A randomized controlled trial protocol in pediatric stem cell transplant.

Medication non-adherence rates in children range between 50% and 80% in the United States. Due to multifaceted outpatient routines, children receiving hematopoietic stem cell transplant (HCT) are at especially high risk of non-adherence, which can be life-threatening. Although digital health interventions have been effective in improving non-adherence in many pediatric conditions, limited research has examined their benefits among families of children receiving HCT.

The experiences of families of children with cancer during the COVID-19 pandemic: A qualitative exploration.

Objectives: The COVID-19 pandemic posed new challenges to physical and psychological well-being. Families with pediatric cancer patients were particularly vulnerable due to changes like children staying at home, hospital policy shifts, and caring for an immunocompromised child. Limited research exists on COVID-19's effects on these families.

Study protocol for FUTURES: Testing a web-based reproductive health education program for adolescent and young adult males with sickle cell disease.

Individuals with sickle cell disease are increasingly surviving into adulthood, many of whom have interest in future biological parenthood. Reproductive health knowledge is low among adolescent and young adult males and their caregivers. Their understanding of these topics is needed to optimize their reproductive health outcomes.

Reproductive Health Counseling among Youth with Sickle Cell Disease.

Study Objective: Reproductive health counseling is important for youth with sickle cell disease (SCD) given that they experience potential infertility risks from SCD and its treatments and high rates of unplanned pregnancies. Thus, the objective of this study was to describe documented occurrences of reproductive health counseling among youth with SCD and examine differences in counseling by sociodemographic and treatment characteristics.

Methods: Data were abstracted from 167 electronic medical records of patients (age = 14-21, 54% female) with SCD (1/01/2015-12/31/19) at 2 sites (Nationwide Children's Hospital and Hassenfeld Children's Hospital at NYU Langone).

Communication within families about advanced pediatric cancer: A qualitative study.

Objectives: This qualitative study examined how families share information and feelings about advanced pediatric cancer from the perspective of both parents and children, as well as how these perspectives vary by child developmental stage.

Methods: Participants (24 mothers, 20 fathers, 23 youth [children and adolescents]) were from a larger longitudinal study at an academic pediatric hospital. Eligible youth had advanced cancer (physician-estimated prognosis of <60%, relapse, or refractory disease), were aged 5-19 years (>8 years old to participate independently), had an English-speaking parent, and lived within 140 miles of the hospital.

Study protocol for fertility preservation discussions and decisions: A family-centered psychoeducational intervention for male adolescents and emerging adults newly diagnosed with cancer and their families.

Many childhood cancer survivors desire biological children but are at risk for infertility after treatment. One option for mitigating risk is the use of fertility preservation prior to gonadotoxic therapy. Adolescents and emerging adults may rely on their parents to help them decide whether to use fertility preservation.

Band-Edge Engineering To Eliminate Radiation-Induced Defect States in Perovskite Scintillators.

Under radiative environments such as extended hard X- or γ-rays, degradation of scintillation performance is often due to irradiation-induced defects. To overcome the effect of deleterious defects, novel design mitigation strategies are needed to identify and design more resilient materials. The potential for band-edge engineering to eliminate the effect of radiation-induced defect states in rare-earth-doped perovskite scintillators is explored, taking Ce-doped LuAlO as a model material system, using density functional theory (DFT)-based DFT + and hybrid Heyd-Scuseria-Ernzerhof (HSE) calculations.

Intramolecular C-H Functionalization Followed by a [2 + 2] Addition via an Intermediate Nickel-Nitridyl Complex.

Irradiation of a disphenoidal Ni(II) azido complex, [Cz (Pyr )NiN] (1), revealed an unprecedented nickel complex, [Cz (Pyr )(NH-Pyr )] (2), in >90% isolated yield. As evidenced by single-crystal X-ray diffraction, 2 is produced by double intramolecular C-H activation of a putative nickel-nitridyl intermediate, [Cz (Pyr )Ni-⃛N]. Calculations support the generation of an intermediate with significant nitridyl radical character after the loss of N, which, in turn, undergoes tandem C-H activations, leading to functionalized intermediates and products.

Physics-informed machine learning for inorganic scintillator discovery.

Applications of inorganic scintillators-activated with lanthanide dopants, such as Ce and Eu-are found in diverse fields. As a strict requirement to exhibit scintillation, the 4f ground state (with the electronic configuration of [Xe]4f 5d) and 5d lowest excited state (with the electronic configuration of [Xe]4f 5d) levels induced by the activator must lie within the host bandgap. Here we introduce a new machine learning (ML) based search strategy for high-throughput chemical space explorations to discover and design novel inorganic scintillators.

Piezomagnetism and magnetoelastic memory in uranium dioxide.

The thermal and magnetic properties of uranium dioxide, a prime nuclear fuel and thoroughly studied actinide material, remain a long standing puzzle, a result of strong coupling between magnetism and lattice vibrations. The magnetic state of this cubic material is characterized by a 3-k non-collinear antiferromagnetic structure and multidomain Jahn-Teller distortions, likely related to its anisotropic thermal properties. Here we show that single crystals of uranium dioxide subjected to strong magnetic fields along threefold axes in the magnetic state exhibit the abrupt appearance of positive linear magnetostriction, leading to a trigonal distortion.

Determination of Krypton Diffusion Coefficients in Uranium Dioxide Using Atomic Scale Calculations.

We present a study of the diffusion of krypton in UO using atomic scale calculations combined with diffusion models adapted to the system studied. The migration barriers of the elementary mechanisms for interstitial or vacancy assisted migration are calculated in the DFT+U framework using the nudged elastic band method. The attempt frequencies are obtained from the phonon modes of the defect at the initial and saddle points using empirical potential methods.

Development of Xe and Kr empirical potentials for CeO2, ThO2, UO2 and PuO2, combining DFT with high temperature MD.

The development of embedded atom method (EAM) many-body potentials for actinide oxides and associated mixed oxide (MOX) systems has motivated the development of a complementary parameter set for gas-actinide and gas-oxygen interactions. A comprehensive set of density functional theory (DFT) calculations were used to study Xe and Kr incorporation at a number of sites in CeO2, ThO2, UO2 and PuO2. These structures were used to fit a potential, which was used to generate molecular dynamics (MD) configurations incorporating Xe and Kr at 300 K, 1500 K, 3000 K and 5000 K.
