A tackler correctly adhering to the tackle instruction in a front-on, one-on-one torso tackle alters the peak inertial head kinematics of the ball carrier but not the tackler.

Objectives: To evaluate if the tackler correctly adhering, or not, to four different instructions of legal front-on one-on-one torso tackles altered the tackler and/or ball carrier peak inertial head kinematics.

Design: Controlled laboratory study.

Methods: Fifteen rugby-code players measured with three-dimensional optoelectronic motion capture performed two tackle instructions from the Australian National Rugby League coaching manual on under (Dominant National Rugby League) and over (Smother National Rugby League) the ball tackles, and two novel variants of these (under, Dominant, Torso Stick; over, Smother, Pop, Lock).

Determining the time to cholangiocarcinoma in pediatric-onset PSC-IBD.

Primary sclerosing cholangitis (PSC) is a risk factor for cholangiocarcinoma. When a child is diagnosed with both PSC and inflammatory bowel disease (IBD), evidence-based information on counseling families and risk management of developing cholangiocarcinoma is limited. In this case series (PubMed/collaborators), we included patients with PSC-IBD who developed cholangiocarcinoma and contacted authors to determine an event curve specifying the time between the second diagnosis (IBD or PSC) and a diagnosis of cholangiocarcinoma.

Adolescents' Self-Reported Exposure to Advertisements for Flavored Tobacco Products After Implementation of a Statewide Ban on Flavored Tobacco Product Sales and Advertising in Massachusetts.

Objectives: Massachusetts signed into law An Act Modernizing Tobacco Control (hereinafter, the Act) in 2019, which restricted retail sales of flavored tobacco products, including menthol cigarettes. This study assessed differences in advertising exposure to flavored tobacco products among adolescents in Massachusetts compared with adolescents in 4 neighboring states after passage of the Act.

Methods: We collected monthly cross-sectional survey data from April 2021 through August 2022 among a convenience sample of adolescents (aged 13-17 y) in Massachusetts and 4 control states: Connecticut, New Hampshire, Rhode Island, and Vermont.

Practical considerations in the establishment of psychedelic research programs.

Rationale: There is increasing interest in establishing psychedelic research programs at academic medical centers. However, psychedelics are intensely psychoactive, carry considerable sociopolitical baggage, and most are Schedule I drugs, creating significant potential impediments to implementation. There is little formal guidance for investigators on navigating the complex on-the-ground obstacles associated with establishing psychedelic research programs.

How Child Health Financing and Payment Mitigate and Perpetuate Structural Racism.

Health financing for children and youth comes mainly from commercial sources (especially, a parent's employer-sponsored insurance) and public sources (especially, Medicaid and Children's Health Insurance Plan [CHIP]). These 2 sources serve populations that differ in race and ethnicity. This inherent segregation perpetuates a system of disparities in health and health care.

Clinical presentation and factors associated with gluten exposure in children with celiac disease.

Objectives: The prevalence of celiac disease (CeD) is increasing, yet it is still underdiagnosed, in part because of its heterogeneous presentation. Diagnostic criteria are evolving and management with strict adherence to a gluten-free diet is challenging for many. We aimed to characterize the clinical presentation of CeD among a large multicenter cohort of pediatric patients and to identify factors associated with gluten-free diet adherence.

Prenatal protein malnutrition decreases neuron numbers in the parahippocampal region but not prefrontal cortex in adult rats.

Objective: Prenatal protein malnutrition produces anatomical and functional changes in the developing brain that persist despite immediate postnatal nutritional rehabilitation. Brain networks of prenatally malnourished animals show diminished activation of prefrontal areas and an increased activation of hippocampal regions during an attentional task [1]. While a reduction in cell number has been documented in hippocampal subfield CA1, nothing is known about changes in neuron numbers in the prefrontal or parahippocampal cortices.

Cardiovascular Health Starts in the Womb.

Hypertension has largely been viewed as a disorder of adulthood. Historically, blood pressure (BP) was not routinely measured in children because hypertension was considered uncommon in childhood. It was not until the 1970s that it was apparent that in childhood BP levels were normally lower compared with those in adults, were related to age and growth, and that abnormal BP in children needed different definitions.

Needs assessment for an infant and toddler food allergy curriculum for pediatric residents.

Background: The prevalence of pediatric food allergies is increasing. Although pediatric residents are frontline providers for children with food allergies, little is known about pediatric residents' educational experiences and comfort with infant and toddler food allergy.

Methods: An anonymous online needs assessment survey was created and distributed to 64 residents in one residency program.

Examining Acute Symptoms After Sport-Related Concussion in Collegiate Athletes With Preinjury Migraines.

Objective: To examine whether a personal history of migraines is associated with worse acute symptom burden after sport-related concussion (SRC).

Design: Retrospective cohort study.

Setting: National Collegiate Athletic Association Division III collegiate programs.

Child Protection System Removal and Short-Interval Births Among Individuals With Prenatal Substance Use.

Child protection systems often intervene after substance-exposed births but are not designed to address the postpartum needs of the delivering parent. In this retrospective cohort study, we aimed to estimate the association between early child protection system removal and high-risk subsequent birth trajectories among a cohort of mothers with substance-exposed births in California. Of 6,893 births in 2015 with documented prenatal drug and alcohol exposure, 20.

Treatment of chronic symptoms following mild traumatic brain injury with transcranial LED: a sham run-in pilot study of photobiomodulation therapy.

Primary Objective: We evaluated whether photobiomodulation with red/near infrared light applied transcranially via light emitting diodes (LED) was associated with reduced symptoms and improved cognitive functioning in patients with chronic symptoms following mild traumatic brain injury.

Research Design: Participants (3 men, 6 women; 22-61 years-old) underwent a 6-week intervention involving 18 40-minute transcranial LED treatment sessions.

Methods And Procedures: Reliable change indices were calculated for 10 neuropsychological test scores and 3 self-report questionnaires of subjective cognition, post-concussion symptoms, and depression at baseline and following treatment.

Early childhood malnutrition impairs adult resting brain function using near-infrared spectroscopy.

Introduction: Early childhood malnutrition affects 200+ million children under 5 years of age worldwide and is associated with persistent cognitive, behavioral and psychiatric impairments in adulthood. However, very few studies have investigated the long-term effects of childhood protein-energy malnutrition (PEM) on brain function using a functional hemodynamic brain imaging technique.

Objective And Methods: This study aims to investigate functional brain network alterations using near infrared spectroscopy (NIRS) in adults, aged 45-51 years, from the Barbados Nutrition Study (BNS) who suffered from a single episode of malnutrition restricted to their first year of life (n = 26) and controls (n = 29).

Non-Host Factors Influencing Onset and Severity of Celiac Disease.

Celiac disease (CeD) is a chronic autoimmune condition driven by gluten ingestion in genetically predisposed individuals, resulting in inflammatory lesions in the proximal small intestine. Although the presence of specific HLA-linked haplotypes and gluten consumption are necessary for disease development, they alone do not account for the variable onset of CeD in susceptible individuals. This review explores the multifaceted role of non-host factors in CeD development, including dietary and microbial influences.

Needs Assessment of Residents and Nurses for Interprofessional Cross-Cultural Curriculum.

Background: Clinicians must learn to care for patients from different cultures. They must also work in teams for optimal outcomes. Few studies have analysed the intersection of cross-cultural care and interprofessional education.

Zonulin as a Biomarker for the Development of Celiac Disease.

Objectives: Increased intestinal permeability seems to be a key factor in the pathogenesis of autoimmune diseases, including celiac disease (CeD). However, it is unknown whether increased permeability precedes CeD onset. This study's objective was to determine whether intestinal permeability is altered before celiac disease autoimmunity (CDA) in at-risk children.

Giving Literal Thanks: An ACGME-Sponsored Initiative to Bring Residents Back to the Bedside.

Resident burnout is at an all-time high. In response, the Accreditation Council for Graduate Medical Education (ACGME) developed the Back to Bedside grant for resident-led burnout interventions that increase the time residents spend with patients. We designed a resident-patient reading intervention, Giving Literal Thanks (GLT), intended to increase meaningful time residents spend with patients and thereby decrease burnout.
