Children and Restraints Study in Emergency Ambulance Transport-Cardiopulmonary Resuscitation (CARSEAT-CPR): An Observational Cohort Study of a Simulated Pediatric Cardiac Arrest.

Objectives: To compare the ability to perform basic life support (BLS) skills on children and infants in a moving ambulance whether or not they are properly secured to the stretcher.

Methods: Emergency Medicine Services provider ability to perform BLS skills was measured in moving ambulances on a closed course using an analog for child and infant cardiac arrest. Data were compared for child and infant manikins secured to the stretcher via different methods in simulated patient resuscitations performed by 24 participants.

Effects of 28-day nose-only inhalation of PCB52 (2,2',5,5'-Tetrachlorobiphenyl) on the brain transcriptome.

A semi-volatile polychlorinated biphenyl (PCB) congener, PCB52, is present in the indoor air of schools; however, the effects of inhaled PCB52 on the brain have not been investigated. This study exposed male Sprague-Dawley rats at 39 days of age and female rats at 42 days of age to PCB52 for 4 hours per day over 28 consecutive days through nose-only inhalation. Neurobehavioral tests were conducted during the last 5 days of exposure.

Comparison of Administration of 8-Milligram and 4-Milligram Intranasal Naloxone by Law Enforcement During Response to Suspected Opioid Overdose - New York, March 2022-August 2023.

In 2021, an 8-mg intranasal naloxone product was approved by the Food and Drug Administration; however, no studies have examined outcomes among persons who receive the 8-mg naloxone product and those who receive the usual 4-mg product. During March 2022-August 2023, New York State Department of Health (NYSDOH) supplied some New York State Police (NYSP) troops with 8-mg intranasal naloxone; other troops continued to receive 4-mg intranasal naloxone to treat suspected opioid overdose. NYSP submitted detailed reports to NYSDOH when naloxone was administered.

Prehospital Chest Pain Management: Disparity Based on Homeless Status.

Background: People experiencing homelessness may use emergency medical services to access health care. We sought to examine the relationship between homelessness and prehospital evaluation and treatment of chest pain.

Methods: We obtained 2019 data of all emergency medical services activations from a single 9-1-1 provider in San Francisco, California with a clinician's primary impression of chest pain.

Children and Restraints Study in Emergency Ambulance Transport: An Observational Study and Analysis of Current Pediatric Ambulance Transport Practices.

Objectives: The aims of this study were to identify the pediatric transport methods used by Emergency Medical Services (EMS) personnel in our area and to highlight the need for federal standards to unify prehospital transport of children.

Methods: Children and Restraints Study in Emergency Ambulance Transport is a retrospective observational study of EMS arrivals to an academic pediatric emergency department for 1 year. Review of existing security footage from the ambulance entrance focused on the appropriateness of the selected restraints and the correctness of their application.

Naloxone administration by law enforcement officers in New York State (2015-2020).

Background: The COVID-19 pandemic has amplified the need for wide deployment of effective harm reduction strategies in preventing opioid overdose mortality. Placing naloxone in the hands of key responders, including law enforcement officers who are often first on the scene of a suspected overdose, is one such strategy. New York State (NYS) was one of the first states to implement a statewide law enforcement naloxone administration program.

Adolescent ethanol drinking promotes hyperalgesia, neuroinflammation and serotonergic deficits in mice that persist into adulthood.

Adolescent alcohol use can permanently alter brain function and lead to poor health outcomes in adulthood. Emerging evidence suggests that alcohol use can predispose individuals to pain disorders or exacerbate existing pain conditions, but the underlying neural mechanisms are currently unknown. Here we report that mice exposed to adolescent intermittent access to ethanol (AIE) exhibit increased pain sensitivity and depressive-like behaviors that persist for several weeks after alcohol cessation and are accompanied by elevated CD68 expression in microglia and reduced numbers of serotonin (5-HT)-expressing neurons in the dorsal raphe nucleus (DRN).

Directed movement toward, translocation along, penetration into and exit from vascular networks by breast cancer cells in 3D.

We developed a computer-assisted platform using laser scanning confocal microscopy to 3D reconstruct in real-time interactions between metastatic breast cancer cells and human umbilical vein endothelial cells (HUVECs). We demonstrate that MB-231 cancer cells migrate toward HUVEC networks, facilitated by filopodia, migrate along the network surfaces, penetrate into and migrate within the HUVEC networks, exit and continue migrating along network surfaces. The system is highly amenable to 3D reconstruction and computational analyses, and assessments of the effects of potential anti-metastasis monoclonal antibodies and other drugs.

Bispectral EEG (BSEEG) quantifying neuro-inflammation in mice induced by systemic inflammation: A potential mouse model of delirium.

Most of the animal studies using inflammation-induced cognitive change have relied on behavioral testing without objective and biologically solid methods to quantify the severity of cognitive disturbances. We have developed a bispectral EEG (BSEEG) method using a novel algorithm in clinical study. This method effectively differentiates between patients with and without delirium, and predict long-term mortality.

Injection laser system for Advanced Radiographic Capability using chirped pulse amplification on the National Ignition Facility.

We report on the design, performance, and qualification of the injection laser system designed to deliver joule-level chirped pulse beamlets arranged in dual rectangular beam formats into two main laser amplifier beamlines of the National Ignition Facility. The system is designed to meet the requirements of the Advanced Radiographic Capability upgrade with features that deliver performance, adjustability, and long-term reliability.

Implementation of a Prehospital Patella Dislocation Reduction Protocol.

Acute patella dislocations account for up to 3% of all knee injuries. Prehospital care of patella dislocation often includes knee immobilization and pain management, but in the wilderness environment patella reductions are often performed by basic life support providers. Given the potential benefits of early reduction, the perceived low risk of harm and precedent with which the procedure can be performed, patella reduction was added to the EMT scope of practice in New York State.

Non-Auto-Injector Epinephrine Administration by Basic Life Support Providers: A Literature Review and Consensus Process.

Anaphylaxis is a life-threatening condition with a known effective prehospital intervention: parenteral epinephrine. The National Association of EMS Physicians (NAEMSP) advocates for emergency medical services (EMS) providers to be allowed to carry and administer epinephrine. Some states constrain epinephrine administration by basic life support (BLS) providers to administration using epinephrine auto-injectors (EAIs), but the cost and supply of EAIs limits the ability of some EMS agencies to provide epinephrine for anaphylaxis.

Transport Home and Terminal Extubation by Emergency Medical Services: An Example of Innovation in End-of-Life Care.

For most terminally ill patients, the preferred place of death is home. Previous literature has demonstrated the feasibility of at-home terminal extubation performed by critical care and hospice physicians. This case report describes a terminal extubation performed by a paramedic under the direct supervision of an Emergency Medical Services physician in the patient's home.

The Role of Redox Dysregulation in the Effects of Prenatal Stress on Embryonic Interneuron Migration.

Maternal stress during pregnancy is associated with increased risk of psychiatric disorders in offspring, but embryonic brain mechanisms disrupted by prenatal stress are not fully understood. Our lab has shown that prenatal stress delays inhibitory neural progenitor migration. Here, we investigated redox dysregulation as a mechanism for embryonic cortical interneuron migration delay, utilizing direct manipulation of pro- and antioxidants and a mouse model of maternal repetitive restraint stress starting on embryonic day 12.

Quality Assessment of Expired Naloxone Products from First-Responders' Supplies.

Naloxone is an opioid receptor antagonist that reverses life-threatening effects of opioid overdose. Since the 1970s, naloxone products have been developed as injectable solutions, and more recently as nasal sprays. Naloxone products have saved many lives in emergency settings.

Decision-Making in the Moments Before Death: Challenges in Prehospital Care.

Background: The primary charge of Emergency Medical Services (EMS) is to save lives. However, EMS personnel are frequently called to scenes where prolonging life may not be the primary goal. When someone is nearing death, family members may feel compelled to call 9-1-1 because they are feeling uncertain about how to manage symptoms at the end of life.

Multiple Naloxone Administrations Among Emergency Medical Service Providers is Increasing.

Background: Opioid overdoses are at epidemic levels in the United States. Emergency Medical Service (EMS) providers may administer naloxone to restore patient breathing and prevent respiratory arrest. There was a need for contemporary data to examine the number of naloxone administrations in an EMS encounter.

Basic Life Support Access to Injectable Epinephrine across the United States.

Background: Aggressive epinephrine administration has growing support in the treatment of anaphylaxis, a life-threatening allergic reaction. Emergency Medical Services (EMS) providers are frequently in a position to provide the first care to someone experiencing an anaphylactic reaction. Intramuscular injection of epinephrine is the definitive pharmacologic treatment for many associated symptoms.

Enabling Donation after Cardiac Death in the Emergency Department: Overcoming Clinical, Legal, and Ethical Concerns.

Background: In light of the growing gap between candidates for organ donation and the actual number of organs available, we present a unique case of organ donation after cardiac death. We hope to open a discussion regarding organ procurement from eligible donors in the prehospital and emergency department setting.

Case: This case study, involving an otherwise healthy man who, after suffering an untimely death, was able to successfully donate his organs, highlights the need to develop an infrastructure to make this type of donation a viable and streamlined option for the future.
