Racial Disparity in Mechanical Thrombectomy Utilization: Multicenter Registry Results From 2016 to 2020.

Background Previous studies on racial disparity in mechanical thrombectomy (MT) treatment of acute large vessel occlusion stroke lack individual patient data that influence treatment decision-making. We assessed patient-level data in a large US health care system from 2016 to 2020 for racial disparities in MT utilization and eligibility. Methods and Results A retrospective study was performed of 34 596 patients admitted to 43 hospitals from January 2016 to September 2020.

Current Guidelines for Classifying and Diagnosing Cervical Dystonia: Empirical Evidence and Recommendations.

Background: The dystonias are phenotypically and etiologically heterogenous disorders. Many proposals and a consensus recommendation have been provided for the diagnosis and classification of the dystonias, but these recommendations serve only as general guidelines. Current diagnosis and classification may still depend on clinical judgment causing different opinions.

Lisdexamfetamine Therapy in Paroxysmal Non-kinesigenic Dyskinesia Associated with the -N999S Variant.

Background: -linked channelopathy is a rare movement disorder first reported in 2005. Paroxysmal non-kinesigenic dyskinesia (PNKD) in -linked channelopathy is the most common symptom in patients harboring the -N999S mutation. PNKD episodes occur up to hundreds of times daily with significant morbidity and limited treatment options, often in the context of epilepsy.

High-Flow Nasal Oxygen Therapy in Acute Hypoxemic Respiratory Failure: Concise Review on Technology and Initial Methodology.

High-flow nasal cannula oxygen therapy (HFNCOT) system consists of an air/oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 80 L/min. The system includes a blender, active humidifier, single heated tube, and nasal cannula. HFNCOT has many physiological advantages compared with other standard oxygen therapies, such as anatomical dead space washout, more constant fraction of inspired oxygen, positive end-expiratory (PEEP) effect, supplement of adequate humidification and maintenance of muco-ciliary function.

Systemic administration of dendrimer N-acetyl cysteine improves outcomes and survival following cardiac arrest.

Cardiac arrest (CA), the sudden cessation of effective cardiac pumping function, is still a major clinical problem with a high rate of early and long-term mortality. Post-cardiac arrest syndrome (PCAS) may be related to an early systemic inflammatory response leading to exaggerated and sustained neuroinflammation. Therefore, early intervention with targeted drug delivery to attenuate neuroinflammation may greatly improve therapeutic outcomes.

Sex trafficking screening and intervention in the emergency department: A scoping review.

Introduction: Human sex trafficking is a global public health crisis. Emergency departments (EDs) are important access points for trafficked persons who seek medical care. However, because of victims' hesitancy to disclose their situation and health care practitioners' lack of training and institutional protocols, many trafficked persons go unrecognized.

Associations Between Eight Earth Observation-Derived Climate Variables and Enteropathogen Infection: An Independent Participant Data Meta-Analysis of Surveillance Studies With Broad Spectrum Nucleic Acid Diagnostics.

Diarrheal disease, still a major cause of childhood illness, is caused by numerous, diverse infectious microorganisms, which are differentially sensitive to environmental conditions. Enteropathogen-specific impacts of climate remain underexplored. Results from 15 studies that diagnosed enteropathogens in 64,788 stool samples from 20,760 children in 19 countries were combined.

Building a virtual community of practice for medical students: The Global Emergency Medicine Student Leadership Program.

Virtual communities of practice (VCoPs) facilitate distance learning and mentorship by engaging members around shared knowledge and experiences related to a central interest. The American College of Emergency Physicians and Emergency Medicine Residents' Association's Global Emergency Medicine Student Leadership Program (GEM-SLP) provides a valuable model for building a VCoP for GEM and other niche areas of interest. This VCoP facilitates opportunities for experts and mentees affiliated with these national organizations to convene regularly despite barriers attributed to physical distance.

Body Composition and Incident Heart Failure in Older Adults: Results From 2 Prospective Cohorts.

Background Aging is associated with central fat redistribution and skeletal muscle decline, yet the relationships of tissue compartments with heart failure (HF) remain incompletely characterized. We assessed the contribution of body composition to incident HF in elders. Methods and Results Participants from 2 older cohorts who completed dual-energy X-ray absorptiometry (DEXA) and, in one cohort, computed tomography were included.

How Point-of-Care Ultrasound Led to a Diagnosis of May-Thurner Syndrome.

A 65-year-old man with a history of a left-sided inguinal hernia presented with three days of left-sided groin pain worsened with exertion and fatigue. The patient was afebrile but tachycardic, and physical examination revealed a tender, erythematous immobile bulge in his left groin. Laboratory studies revealed leukocytosis.

Worm Sign: A possible first-trimester sonographic marker for intracranial haemorrhage resulting in significant cortical disruption.

Fetal intracranial haemorrhage (ICH) is a pathophysiological process involving haemorrhagic and hypoxic-ischaemic insults resulting in antenatal brain damage. Insults to the central nervous system are usually not detected until the second or third trimester. In this case presentation, we present a possible prenatal ultrasound marker, 'worm sign', representing cortical disruption secondary to suspected ICH at 13 weeks' gestation.

Hispanic/Latino-Serving Hospitals Provide Less Targeted Temperature Management Following Out-of-Hospital Cardiac Arrest.

Background Variation exists in outcomes following out-of-hospital cardiac arrest (OHCA), but whether racial and ethnic disparities exist in post-arrest provision of targeted temperature management (TTM) is unknown. Methods and Results We performed a retrospective analysis of a prospectively collected cohort of patients who survived to admission following OHCA from the Cardiac Arrest Registry to Enhance Survival, whose catchment area represents ~50% of the United States from 2013-2019. Our primary exposure was race/ethnicity and primary outcome was utilization of TTM.

Pediatric sweet syndrome.

Pediatric Sweet syndrome is a rare dermatosis often triggered by a prodromal illness or infection and characterized histologically by a dense neutrophilic infiltrate. We report a 2-year-old girl with a classic presentation of Sweet syndrome following an acute thumb paronychia, who had a negative history of malignancy or immunodeficiency.

Hyperkalemia management in the emergency department: An expert panel consensus.

Hyperkalemia is a common electrolyte abnormality identified in the emergency department (ED) and potentially fatal. However, there is no consensus over the potassium threshold that warrants intervention or its treatment algorithm. Commonly used medications are at best temporizing measures, and the roles of binders are unclear in the emergent setting.

Addressing end-of-life care in the chronically ill: Conversations in the emergency department.

Patients present to the emergency department in various stages of chronic illness. Advance directives (ADs) aid emergency physicians in making treatment decisions, but only a minority of Americans have completed an AD, and the percentage of those who have discussed their end-of-life wishes may be even lower. This article addresses the use of common ADs and roadblocks to their use from the perspectives of families, patients, and physicians.

Stratifying the Risk of Cardiovascular Disease in Obstructive Sleep Apnea Using Machine Learning.

Objectives/hypothesis: Obstructive sleep apnea (OSA) is associated with higher risk of morbidity and mortality related to cardiovascular disease (CVD). Due to overlapping clinical risk factors, identifying high-risk patients with OSA who are likely to develop CVD remains challenging. We aimed to identify baseline clinical factors associated with the future development of CVD in patients with OSA.

Illustrated State-of-the-Art Capsules of the ISTH 2020 Congress.

This year's Congress of the International Society of Thrombosis and Haemostasis (ISTH) was hosted virtually from Philadelphia July 17-21, 2021. The conference, now held annually, highlighted cutting-edge advances in basic, population and clinical sciences of relevance to the Society. Despite being held virtually, the 2021 congress was of the same scope and quality as an annual meeting held in person.

SARS-CoV-2 infection and paediatric endocrine disorders: Risks and management considerations.

Background: Coronavirus-19 (COVID-19) is a disease caused by the SARS-CoV-2 virus, the seventh coronavirus identified as causing disease in humans. The SARS-CoV-2 virus has multiple potential pathophysiologic interconnections with endocrine systems, potentially causing disturbances in glucose metabolism, hypothalamic and pituitary function, adrenal function and mineral metabolism. A growing body of data is revealing both the effects of underlying endocrine disorders on COVID-19 disease outcome and the effects of the SARS-CoV-2 virus on endocrine systems.

Chest imaging of hypersensitivity pneumonitis induced by heroin abuse.

Long-term abuse of nasally inhaled substances such as heroin can result in life-threatening hypersensitivity pneumonitis and respiratory distress. In the setting of hypoxia, a chest CTA is often necessary to see the extent of the lung involvement and to rule out pulmonary emboli.
