Importance Individuals who survived COVID-19 often report persistent symptoms, disabilities, and financial consequences. However, national longitudinal estimates of symptom burden remain limited. Objective To measure the incidence changes over time in disability, status after COVID-19–related hospitalization. Design, Setting, Participants A US multicenter prospective cohort study with 1-, 3-, 6-month postdischarge visits was conducted at 44 sites participating National Heart, Lung, Blood...
Abstract Objective The current national opioid epidemic is a public health emergency. We have identified an outbreak of exaggerated toxicity caused by fentanyl adulterated tablets purchased on the street as hydrocodone/acetaminophen. Methods Over 8‐day period in late March 2016, total 18 patients presented to our institution with toxicity. provided similar history: ingesting their “normal dose” hydrocodone/acetaminophen but more pronounced symptoms. Toxicology testing and analysis was...
Current guidelines conflict on the management of older adults who have blunt head trauma taking anticoagulant and antiplatelet medications. This is partially due to limited data comparing patients are these medications with those not.To investigate incidence delayed traumatic intracranial hemorrhage in trauma, including medications.This prospective observational cohort study included 55 years had were transported via emergency medical services between August 1, 2015, September 30, 2016. The...
The use of N-acetylcysteine (NAC) remains the standard care for treatment acetaminophen (APAP) toxicity and overdose. Currently, there is growing evidence to suggest that massive overdose associated with increased hepatotoxicity despite timely administration NAC. This raises question as whether an dose intravenous (IV) NAC should be used in setting APAP ingestion. study aimed evaluate rate after treated 3 different regimens.This was a retrospective cohort conducted by electronic medical...
Exposures to hydrazines occur during aeronautic and space operations pose a potential risk personnel. Historically, extensive preparatory countermeasures have been taken due concern for severe toxicity. This study seeks better understand manifestations of acute occupational exposures hydrazine guide recommendations management.
Background and aims The Psychoactive Surveillance Consortium Analysis Network (PSCAN) is a national network of academic emergency departments (ED), analytical toxicologists pharmacologists that collects clinical data paired with biological samples to identify improve treatments medical conditions arising from use new psychoactive substances (NPS). aim this study was gather drug identification NPS users who presented EDs within PSCAN during its first year (2016–17). Design Observational...
An increasing number of jurisdictions have legalized recreational cannabis for adult use. The subsequent availability and marketing has led to a parallel increase in rates severity pediatric intoxications. We explored predictors severe outcomes patients who presented the emergency department with intoxication.In this prospective cohort study, we collected data on all (<18 years) intoxication from August 2017 through June 2020 participating sites Toxicology Investigators Consortium. In cases...
Introduction: Dabigatran etexilate was the first direct-acting oral anticoagulant approved in UnitedStates. The prevalence of intracranial hemorrhage after blunt head trauma patients on dabigatranis currently unknown, complicating adequate ability to accurately compare risks and benefitsof dabigatran alternative anticoagulants. We aimed determine intracranialhemorrhage for presenting a Level I center.Methods: This is retrospective observational study adult who presented toa center received...
