Creating a plasma coordination center to support COVID-19 outpatient trials across a national network of hospital blood banks.

Introduction: In response to the COVID-19 pandemic, we rapidly implemented a plasma coordination center, within two months, to support transfusion for two outpatient randomized controlled trials. The center design was based on an investigational drug services model and a Food and Drug Administration-compliant database to manage blood product inventory and trial safety.

Methods: A core investigational team adapted a cloud-based platform to randomize patient assignments and track inventory distribution of control plasma and high-titer COVID-19 convalescent plasma of different blood groups from 29 donor collection centers directly to blood banks serving 26 transfusion sites.

Metabolic syndrome and mobility dysfunction in older adults with and without histories of traumatic brain injury: The mediating role of cognition.

Objective: Older adults are more susceptible than the general population to developing metabolic syndrome (i.e., three or more cardiovascular risk factors [MetS]), physical limitations, and traumatic brain injury (TBI).

Adverse Events in Patients Transitioning From the Emergency Department to the Inpatient Setting.

Objectives: The objective of this study was to determine the incidence and types of adverse events (AEs), including preventable and ameliorable AEs, in patients transitioning from the emergency department (ED) to the inpatient setting. A second objective was to examine the risk factors for patients with AEs.

Methods: This was a prospective cohort study of patients at risk for AEs in 2 urban academic hospitals from August 2020 to January 2022.

Prioritising patients for publicly funded bariatric surgery in Queensland, Australia.

Objectives: This study reports the development and pilot application of the Bariatric Surgery Assessment and Prioritisation Tool (BAPT) for use in a public health system. The BAPT was designed as a patient prioritisation instrument to assess patients with excessive weight and type 2 diabetes suitable for bariatric surgery. We assessed whether the instrument successfully identified those who gained the greatest benefits including weight loss, diabetes remission, reduction in comorbidities, and health-related quality of life (HR-QoL).

Mind the GAHP: A novel protocol for improved vascular access in the hypotensive patient.

Background: Obtaining intravenous access in hypotensive patients is challenging and may critically delay resuscitation. The Graduated Vascular Access for Hypotensive Patient (GAHP) protocol leverages intraosseous fluid boluses to specifically dilate proximal veins. This study aims to evaluate the efficacy of GAHP in maximizing venous targets through early distal intraosseous access and a small fluid bolus.

Influence of Cooling duration on Efficacy in Cardiac Arrest Patients (ICECAP): study protocol for a multicenter, randomized, adaptive allocation clinical trial to identify the optimal duration of induced hypothermia for neuroprotection in comatose, adult survivors of after out-of-hospital cardiac arrest.

Background: Cardiac arrest is a common and devastating emergency of both the heart and brain. More than 380,000 patients suffer out-of-hospital cardiac arrest annually in the USA. Induced cooling of comatose patients markedly improved neurological and functional outcomes in pivotal randomized clinical trials, but the optimal duration of therapeutic hypothermia has not yet been established.

A Modified Floxuridine Reduced-Dose Protocol for Patients with Unresectable Colorectal Liver Metastases Treated with Hepatic Arterial Infusion.

Background: Most patients treated with the standard dosing protocol (SDP) of hepatic arterial infusion (HAI) floxuridine require dose holds and reductions, thereby limiting their HAI therapy. We hypothesized that a modified dosing protocol (MDP) with a reduced floxuridine starting dose would decrease dose holds, dose reductions, and have similar potential to convert patients with unresectable colorectal liver metastases (uCRLM) to resection.

Patients And Methods: We reviewed our institutional database of patients with uCRLM treated with HAI between 2016 and 2022.

Influence of Cooling duration on Efficacy in Cardiac Arrest Patients (ICECAP): study protocol for a multicenter, randomized, adaptive allocation clinical trial to identify the optimal duration of induced hypothermia for neuroprotection in comatose, adult survivors of after out-of-hospital cardiac arrest.

Background: Cardiac arrest is a common and devastating emergency of both the heart and brain. More than 380,000 patients suffer out-of-hospital cardiac arrest annually in the United States. Induced cooling of comatose patients markedly improved neurological and functional outcomes in pivotal randomized clinical trials, but the optimal duration of therapeutic hypothermia has not yet been established.

Improving equitable access to publicly funded bariatric surgery in Queensland, Australia.

BackgroundPeople living in regional Queensland, Australia, have less access to health care than their metropolitan neighbours; a gap that is wider if they are also of Aboriginal and Torres Strait Islander ethnicity. The Bariatric Surgery Initiative (BSI) aims to provide metabolic bariatric surgery as a public service accessible to all Queenslanders for patients with morbid obesity according to need, regardless of location or ethnicity.MethodsWe investigated the BSI's progress in closing the metro-regional gap by comparing the distribution of referrals for surgery with the geographic and ethnic spread of obesity across Queensland in 2017-2019.

Emergency Physicians' Ethical Issues with Hospital Business Models.

Background: The changing hospital business model has raised ethical issues for emergency physicians (EPs) in a healthcare system that often prioritizes profits over patient welfare. For-profit hospitals, driven by profit motives, may prioritize treating patients with lucrative insurance plans and those who can afford expensive treatments. Private equity investors, who now own many for-profit hospitals, focus on short-term financial gains, leading to cost-cutting measures and pressure on EPs to prioritize financial goals over patient welfare.

Headpulse measurement can reliably identify large-vessel occlusion stroke in prehospital suspected stroke patients: Results from the EPISODE-PS-COVID study.

Background: Large-vessel occlusion (LVO) stroke represents one-third of acute ischemic stroke (AIS) in the United States but causes two-thirds of poststroke dependence and >90% of poststroke mortality. Prehospital LVO stroke detection permits efficient emergency medical systems (EMS) transport to an endovascular thrombectomy (EVT)-capable center. Our primary objective was to determine the feasibility of using a cranial accelerometry (CA) headset device for prehospital LVO stroke detection.

Outpatient COVID-19 convalescent plasma recipient antibody thresholds correlated to reduced hospitalizations within a randomized trial.

BACKGROUNDCOVID-19 convalescent plasma (CCP) virus-specific antibody levels that translate into recipient posttransfusion antibody levels sufficient to prevent disease progression are not defined.METHODSThis secondary analysis correlated donor and recipient antibody levels to hospitalization risk among unvaccinated, seronegative CCP recipients within the outpatient, double-blind, randomized clinical trial that compared CCP to control plasma. The majority of COVID-19 CCP arm hospitalizations (15/17, 88%) occurred in this unvaccinated, seronegative subgroup.

Anatomical design and production of a novel three-dimensional co-culture system replicating the human flexor digitorum profundus enthesis.

The enthesis, the specialized junction between tendon and bone, is a common site of injury. Although notoriously difficult to repair, advances in interfacial tissue engineering techniques are being developed for restorative function. Most notably are 3D in vitro co-culture models, built to recreate the complex heterogeneity of the native enthesis.

Repair of lateral temporo-sphenoidal encephalocoele via an endoscopic transorbital approach: 3D printed simulation followed by deployment.

Background: A temporo-sphenoidal encephalocoele occurs when temporal lobe herniates through a defect in the greater wing of the sphenoid bone into the sphenoid air sinus. The natural history is not well-understood, though presentation in adulthood with CSF rhinorrhoea and/or meningitis is typical. Lateral pneumatisation of the sphenoid sinus and elevated BMI may be contributory.

COVID-19 convalescent plasma therapy decreases inflammatory cytokines: a randomized controlled trial.

This study examined the role that cytokines may have played in the beneficial outcomes found when outpatient individuals infected with SARS-CoV-2 were transfused with COVID-19 convalescent plasma (CCP) early in their infection. We found that the pro-inflammatory cytokine IL-6 decreased significantly faster in patients treated early with CCP. Participants with COVID-19 treated with CCP later in the infection did not have the same effect.

A comparison of the effect of patient-specific versus weight-based protocols to treat vaso-occlusive episodes in the emergency department.

Background: Vaso-occlusive crises (VOCs) cause debilitating pain and are a common cause of emergency department (ED) visits, for people with sickle cell disease (SCD). Strategies for achieving optimal pain control vary widely despite evidence-based guidelines. We tested existing guidelines and hypothesized that a patient-specific pain protocol (PSP) written by their SCD provider may be more effective than weight-based (WB) dosing of parenteral opiate medication, in relieving pain.

Early antibody treatment, inflammation, and risk of post-COVID conditions.

Approximately 20% of individuals infected with SARS-CoV-2 experienced long-term health effects, as defined PCC. However, it is unknown if there are any early biomarkers associated with PCC or whether early intervention treatments may decrease the risk of PCC. In a secondary analysis of a randomized clinical trial, this study demonstrates that among outpatients with SARS-CoV-2, increased IL-6 at time of infection is associated with increased odds of PCC.

Dynamics of inflammatory responses after SARS-CoV-2 infection by vaccination status in the USA: a prospective cohort study.

Background: Cytokines and chemokines play a critical role in the response to infection and vaccination. We aimed to assess the longitudinal association of COVID-19 vaccination with cytokine and chemokine concentrations and trajectories among people with SARS-CoV-2 infection.

Methods: In this longitudinal, prospective cohort study, blood samples were used from participants enrolled in a multi-centre randomised trial assessing the efficacy of convalescent plasma therapy for ambulatory COVID-19.

The Effect of a Flipped Classroom Learning Model Versus Traditional Lecture Model on Resident's Knowledge Acquisition for Atraumatic Back Pain in the Emergency Department.

Objective: The effectiveness of lecture-based (LB) formats for residency education has recently been challenged as the gold standard. Studies suggest a flipped classroom (FC) lecture improves resident satisfaction, but evidence that showing improved knowledge acquisition is lacking. To determine whether the flipped classroom model improves knowledge acquisition compared to traditional LB model.

Transfusion reactions associated with COVID-19 convalescent plasma in outpatient clinical trials.

Background: COVID-19 convalescent plasma (CCP) is an important therapeutic option for outpatients at high risk of hospitalization from SARS-CoV-2 infection. We assessed the safety of outpatient CCP transfusions administered during clinical trials.

Study Design And Methods: We analyzed data pertaining to transfusion-related reactions from two randomized controlled trials in the U.

The Association between Emergency Department Length of Stay and In-Hospital Mortality in Older Patients Using Machine Learning: An Observational Cohort Study.

The association between emergency department (ED) length of stay (EDLOS) with in-hospital mortality (IHM) in older patients remains unclear. This retrospective study aims to delineate the relationship between EDLOS and IHM in elderly patients. From the ED patients (n = 383,586) who visited an urban academic tertiary care medical center from January 2010 to December 2016, 78,478 older patients (age ≥60 years) were identified and stratified into three age subgroups: 60-74 (early elderly), 75-89 (late elderly), and ≥90 years (longevous elderly).
