Understanding the Sequelae of Invasive Meningococcal Disease in the United States.

Invasive meningococcal disease (IMD) is an uncommon but serious and potentially fatal condition that can result in reduced life expectancy and a broad spectrum of sequelae, many of which may be lifelong and devastating for those who survive the acute disease period. In the United States of America (USA), vaccination is available against the five meningococcal serogroups (A, B, C, W, and Y), but meningococcal vaccination rates among healthy USA adolescents and individuals at high risk because of medical conditions are low, rendering them vulnerable to IMD and its sequelae. Despite the severity of the disease, the clinical impact and rates of IMD sequelae in the USA are poorly understood, as USA-specific data are limited, and the methodology of existing research is heterogenous.

Supporting Stewardship: Funding, Utilization, and Sustainability as Ethical Concerns in Networked Biobanking.

Background: The literature on the ethics of biobanking often overlooks the practical operations of biobanks. The ethics of stewardship requires that biobank resources are used to conduct beneficial science. Networked biobanks have emerged to increase the scientific benefit of biobank resources, but little is known about whether and how operations of networking may accomplish this goal.

The Relationships Among Neighborhood Disadvantage, Mental Health and Developmental Disabilities Diagnoses, and Race/Ethnicity in a U.S. Urban Location.

Childhood health disparities by race have been found. Neighborhood disadvantage, which may result from racism, may impact outcomes. The aim of the study is to describe the distribution of mental health (MH) and developmental disabilities (DD) diagnosis across Child Opportunity Index (COI) levels by race/ethnicity.

Measuring perceived utility of genomic sequencing: Development and validation of the GENEtic Utility (GENE-U) scale for adult screening.

Purpose: As population-based screening programs to identify genetic conditions in adults using genomic sequencing (GS) are increasingly available, validated patient-centered outcome measures are needed to understand participants' experience. We aimed to develop and validate an instrument to assess the perceived utility of GS in the context of adult screening.

Methods: Informed by a 5-domain conceptual model, we used a 5-step approach to instrument development and validation: (1) item writing, (2) cognitive testing, (3) pilot testing and item reduction, (4) psychometric testing, and (5) evaluation of construct validity.

Perspectives of paediatric providers on antibiotic stewardship in a high-prescribing rural region.

Purpose: Understanding drivers of antibiotic use is key to limiting the development of antimicrobial resistance. Outpatient antibiotic prescribing rates vary substantially across and within states. Kentucky is one of the highest prescribing states, and the southeastern region has rates that are drastically higher than the national average and urban areas of the state.

Microglia are dispensable for experience-dependent refinement of mouse visual circuitry.

To test the hypothesized crucial role of microglia in the developmental refinement of neural circuitry, we depleted microglia from mice of both sexes with PLX5622 and examined the experience-dependent maturation of visual circuitry and function. We assessed retinal function, receptive field tuning of visual cortex neurons, acuity and experience-dependent plasticity. None of these measurements detectibly differed in the absence of microglia, challenging the role of microglia in sculpting neural circuits.

The association of manganese overexposure and neurobehavioral function is moderated by arsenic: A metal mixture analysis of children living near coal ash storage sites.

Manganese is an essential element but can be neurotoxic if overexposed. Our previous study found that a higher level of manganese in nail biomarkers from children living near coal ash storage sites was associated with poorer neurobehavioral function. Children living near this type of pollution may be exposed to other metal neurotoxicants and a better understanding of manganese in the context of multiple exposures is needed.

Measuring perceived utility of genomic sequencing: Development and validation of the GENEtic Utility (GENE-U) scale for pediatric diagnostic testing.

Purpose: Measuring the effects of genomic sequencing (GS) on patients and families is critical for translational research. We aimed to develop and validate an instrument to assess parents' perceived utility of pediatric diagnostic GS.

Methods: Informed by a 5-domain conceptual model, the study comprised 5 steps: (1) item writing, (2) cognitive testing, (3) pilot testing and item reduction, (4) psychometric testing, and (5) evaluation of construct validity.

Alzheimer's disease and low-dose radiation therapy: A new hope.

The concept of low-dose radiation (LDR)-induced hormetic responses was initially observed approximately 70 years ago and systematically reviewed along with the discovery of LDR-induced adaptive responses in a cytogenetic study in 1980s. By the end of the 1990s, discussions regarding the potential applications of LDR-induced hormesis and adaptive responses for preventing or treating chronic diseases, such as Alzheimer's disease (AD) had taken place. Until 2016, reports on radiotherapy for the subjects with AD and for genetic AD model mice were published.

A genetically informed longitudinal study of early-life temperament and childhood aggression.

The present study examined the longitudinal associations between three dimensions of temperament - activity, affect-extraversion, and task orientation - and childhood aggression. Using 131 monozygotic and 173 dizygotic (86 same-sex) twin pairs from the Louisville Twin Study, we elucidated the ages, from 6 to 36 months, at which each temperament dimension began to correlate with aggression at age 7. We employed latent growth modeling to show that developmental increases (i.

Ethical and Legal Issues Surrounding Genetic Testing in the NICU.

Clinicians practicing in a modern NICU are noticing an increase in the proportion of patients who undergo genetic testing as well as changes in the types of genetic testing patients receive. These trends are not surprising given the increasing recognition of the genetic causes of neonatal illness and recent advances in genetic technology. Yet, the expansion of genetic testing in the NICU also raises a number of ethical questions.

Effect of an Evaluation Algorithm on CT Utilization in Identifying Appendicitis in Children.

Objective: Our objective was to determine if there was a significant change in computed tomography (CT) utilization or length of stay (LOS) among patients evaluated for acute appendicitis after implementation of an appendicitis evaluation algorithm.

Methods: We conducted a retrospective chart review of patients aged 3-18 years in an urban, tertiary pediatric emergency department with acute abdominal pain, evaluated for appendicitis. Data were collected for 6 months preimplementation and postimplementation of the evaluation algorithm with a 3-month washout period between September 2018 and November 2019.

United States Physicians' Knowledge, Attitudes, and Practices Regarding Meningococcal Vaccination for Healthy Adolescents and Young Adults.

Purpose: The United States Advisory Committee on Immunization Practices (ACIP) recommends vaccination against meningococcal serogroups A, C, W, and Y (MenACWY) for all 11-12-year-olds, with a booster dose for 16-year-olds, and against meningococcal serogroup B (MenB) for 16-23-year-olds under shared clinical decision-making (SCDM). However, uptake of the MenB vaccine and the MenACWY booster dose is low. This study investigated United States physicians' knowledge, attitudes, and practices regarding recommending MenB and MenACWY vaccines to non-high-risk older adolescents and young adults.

Optimizing Facial Aesthetics: Sequential Application of Botulinum Toxin A and Dermal Fillers for Enhanced Results.

In recent years, the field of aesthetic medicine has witnessed significant advancements, offering patients a plethora of options to rejuvenate their appearance. Among the most popular techniques are the administration of botulinum toxin A (BoNT-A) and dermal fillers. This article delves into the rationale and benefits of preparing the face with BoNT-A to weaken depressor muscles before proceeding with dermal filler injections.

Doxapram for the prevention and treatment of apnea in preterm infants.

Background: Apnea of prematurity is a common problem in preterm infants that may have significant consequences on their development. Methylxanthines (aminophylline, theophylline, and caffeine) are effective in the treatment of apnea of prematurity. Doxapram is used as a respiratory stimulant in cases refractory to the methylxanthine treatment.

Emergency departments: An underutilized resource to address pediatric influenza vaccine coverage.

Background: Emergency department (ED) based influenza vaccine (IV) programs have been successful in adults; however, little is known about pediatric ED IV programs in terms of prevalence, feasibility, or successful implementation.

Aims: To describe the reach and effectiveness of IV practices in pediatric EDs, and identify IV facilitators and barriers.

Methods: We assessed, via cross-sectional survey of pediatric ED physicians, number of EDs offering IV to children, vaccines administered annually, and perceived facilitators/barriers to vaccination.
