The Society for Pediatric Radiology Magnetic Resonance Imaging and Emergency and Trauma Imaging Committees' consensus protocol recommendation for rapid MRI for evaluating suspected appendicitis in children.

The imaging evaluation of acute abdominal pain in children with suspected appendicitis has evolved to include rapid abdominopelvic MRI (rMRI) over recent years. Through a collaborative effort between the Magnetic Resonance Imaging (MRI) and Emergency and Trauma Imaging Committees of the Society for Pediatric Radiology (SPR), we conducted a survey on the utilization of rMRI to assess practice specifics and protocols. Subsequently, we present a proposed consensus rMRI protocol derived from the survey results, literature review, and discussion and consensus between committee members.

Teaching for Student and Societal Wellbeing in HPE: Nine Pedagogies for Social Justice.

We currently find ourselves living in precarious times, with old and new social inequities on the rise due to the challenges associated with an unprecedented rise of global migration and neoliberalism, amplified in our post COVID-19 world. Research has demonstrated that there is a high correlation between inequality at the societal level and the overall health and wellbeing of individuals within those societies. We believe that school health and physical education (HPE) has a significant role to play in addressing and acting on social inequities that impact on the wellbeing of both students and society as a whole.

Social Justice Pedagogies in School Health and Physical Education-Building Relationships, Teaching for Social Cohesion and Addressing Social Inequities.

A focus on equity and social justice in school health and physical education (HPE) is pertinent in an era where there are growing concerns about the impact of neoliberal globalization and the precariousness of society. The aim of the present study was to identify school HPE teaching practices that promote social justice and more equitable health outcomes. Data were generated through 20 HPE lesson observations and post-lesson interviews with 13 HPE teachers across schools in Sweden, Norway, and New Zealand.

Utility of applying white blood cell cutoffs to non-diagnostic MRI and ultrasound studies for suspected pediatric appendicitis.

Background: Non-contrast magnetic resonance imaging (MRI) and ultrasound studies in pediatric patients with suspected appendicitis are often non-diagnostic. The primary objective of this investigation was to determine if combining these non-diagnostic imaging results with white blood cell (WBC) cutoffs improves their negative predictive values (NPVs).

Methods: A retrospective chart review was conducted including patients ≤18 years old with suspected appendicitis who had MRI performed with or without a preceding ultrasound study in a pediatric emergency department.

A Complicated Opioid Overdose: A Simulation for Emergency Medicine Residents.

Introduction: Opioid abuse is a growing problem in the United States. As a result, emergency medicine physicians often use naloxone to reverse opioid overdoses. While normally a safe drug, one potential complication of the antidote's use is flash pulmonary edema.

Epithelioid hemangioma of bone: radiologic and magnetic resonance imaging characteristics with histopathological correlation.

Background: Epithelioid hemangioma is a rare vascular tumor that can occur in soft tissues or bone. The tumor is part of a spectrum of vascular tumors that also includes epithelioid hemangioendothelioma and angiosarcoma. When involving the bone, the tumor usually involves the metaphysis or diaphysis of the long tubular bones and most commonly occurs in adults.

5-Methyl-6-phenyl-1,3,5,6-tetrahydro-3,6-methano-1,5-benzodiazocine-2,4-dione (BA 41899): representative of a novel class of purely calcium-sensitizing agents.

BA 41899 (5-methyl-6-phenyl-1,3,5,6-tetrahydro-3,6-methano-1,5- benzodiazocine-2,4-dione, 6) is a structurally novel 1,5-benzodiazocine derivative and represents the prototype of a hitherto unknown class of positive inotropic Ca(2+)-sensitizing agents. It is completely devoid of phosphodiesterase (PDE) III inhibitory activity or any other known inotropic mechanism. BA 41899 (6) exhibits a pharmacological in vitro profile comprising Ca(2+)-sensitizing, positive inotropic, and negative chronotropic effects.

Water transport in concrete.

Chloride contamination is a major source of concrete deterioration. Previous studies of chloride transport use weight-vs.-time analysis on immersed samples to deduct related concrete water exchange properties, based on the assumptions of strictly capillary flow and a well defined transport front.

Metabolic transient studies by NMR.

The time course of phosphocreatine (PC) hydrolysis in humans was measured by 31P-NMR spectroscopy (31P-NMRS) with a time resolution of 10.8 s in the gastrocnemius muscle and a relationship between muscle O2 consumption (VO2) and [PC] was derived from a bioenergetic model. This allowed a direct estimate of the half-time of the intracellular VO2 kinetics (t1/2 VO2) of the contracting human gastrocnemius in aerobic conditions.

Phosphocreatine hydrolysis by 31P-NMR at the onset of constant-load exercise in humans.

The kinetics of phosphocreatine (PC) breakdown in human plantar flexors at the onset of constant-load aerobic exercise was determined by high-resolution 31P-nuclear magnetic resonance spectroscopy (NMRS). The half time of the process (t1/2PC) was obtained by fitting curves (n = 13) from five subjects at various aerobic work loads for which muscle pH was not different from that at rest. Steady-state PC concentration ([PC]) was not < 70% of the resting value and was linearly related to the work load (w) ([PC] = -3.

Myelination of the optic radiation in Leber congenital amaurosis.

We have studied the myelination of the visual pathway by magnetic resonance imaging in seven children (aged 5 months to 16 years) with Leber congenital amaurosis. The corpus geniculatum laterale and the retrogeniculate optic radiation had a normal appearance on MRI in all patients. Therefore we conclude that normal myelination of the optic radiation, as it can be grossly assessed by MRI, can take place even with absent or greatly reduced visual sensory input.
