Project description:Consensus guidelines to protect airway managers during COVID-19 were developed to encourage safe, accurate and swift performance in intubation and extubation, but reintubation was not considered. With the massive surge of patients requiring mechanical ventilation in this COVID-19 pandemic, great incidence of difficult airways may necessitate reintubation. Equipments could be used now in extubation and reintubation are either too expensive and time-consuming in decontamination, or have not gained wide acceptance. Here, we adapted an extubation device from an intubating stylet, which is provided as accessory of endotracheal tube. Such stylet could provide safe access for expediting reintubation both during and after the COVID-19 pandemic, which is inexpensive, single-use, readily available, straightforward to handle, and well-tolerated, thereby benefiting both the patients and healthcare providers.

Project description:OBJECTIVES:There are no societal ultrasound guidelines detailing appropriate patient selection for deep vein thrombosis (DVT) imaging in COVID-19 patients nor are there protocol recommendations aimed at decreasing exposure time for ultrasound technologists. We aimed to provide COVID-19 specific protocol optimization recommendations limiting ultrasound technologist exposure while optimizing patient selection. METHODS:A novel two-pronged algorithm was implemented to limit the DVT ultrasound studies on COVID-19 patients prospectively which included direct physician communication with the care team and a COVID-19 specific imaging protocol was instated to reduce ultrasound technologist exposure. In order to assess pretest risk of DVT, sensitivity and specificity of serum D-Dimer in 500-unit increments from 500 to 8000 ng/mL and a receiver operating characteristic curve (ROC) to assess performance of serum D-Dimer in predicting DVT was generated. Rates of DVT, pulmonary embolism (PE) and scan times were compared using t-test and Fisher's exact test (before and after implementation of the protocol). RESULTS:Direct physician communication resulted in cancellation or deferral of 72% of requested exams in COVID-19 positive patients. A serum D-Dimer > 4000ng/mL yielded a sensitivity of 80% and a specificity of 70% (CI: 0.54-0.86) for venous thromboembolism. Using the COVID-19 specific protocol, there was a significant (50%) reduction in scan time (p<0.0001) in comparison with conventional protocol. CONCLUSION:A direct physician communication policy between imaging physician and referring physician resulted in deferral or cancellation of a majority of requested DVT ultrasound exams. An abbreviated COVID-19 specific imaging protocol significantly decreased exposure time to the ultrasound technologist.

Project description:Background: During gestation, stressors to the fetus, including viral exposure or maternal psychological distress, can fundamentally alter the neonatal epigenome, and may be associated with long-term impaired developmental outcomes. The impact of in utero exposure to the COVID-19 pandemic on the newborn epigenome has yet to be described. Methods: This study aimed to determine whether there are unique epigenetic signatures in newborns who experienced otherwise healthy pregnancies that occurred during the COVID-19 pandemic (Project RESCUE). The pre-pandemic control and pandemic cohorts (Project RESCUE) included in this study are part of a prospective observational and longitudinal cohort study that evaluates the impact of elevated prenatal maternal stress during the COVID-19 pandemic on early childhood neurodevelopment. Using buccal swabs collected at birth, differential DNA methylation analysis was performed using the Infinium MethylationEPIC arrays and linear regression analysis. Pathway analysis and gene ontology enrichment were performed on resultant gene lists. Results: Widespread differential methylation was found between neonates exposed in utero to the pandemic and pre-pandemic neonates. In contrast, there were no apparent epigenetic differences associated with maternal COVID-19 infection during pregnancy. Differential methylation was observed among genomic sites that underpin important neurological pathways that have been previously reported in the literature to be differentially methylated because of prenatal stress, such as NR3C1. Conclusions: The present study reveals that the onset and continuation of the COVID-19 pandemic has fundamentally altered the epigenomes of newborns born during this time, even in otherwise healthy pregnancies, which should be considered in current and future epigenetic studies and may act as a critical biomarker of stress.

Project description:BACKGROUND AND AIM:Minimizing endoscopist exposure to bodily fluids is important for reducing the risk of infection transmission. This study investigated the patient-endoscopist vertical distance necessary to minimize an endoscopist's facial exposure to a patient's visible droplets during upper gastrointestinal endoscopy and the ability of a new device to prevent droplets from reaching the endoscopist's face. METHODS:A model was developed to simulate a patient experiencing a forceful cough during an upper gastrointestinal endoscopy with a model endoscopist. Fluorescent dye was expelled from the model patient's mouth towards the model endoscopist during simulated coughs; dye adhesion to the model endoscopist's face was evaluated using ultraviolet light. The simulation was repeated with the model patient positioned 70-100 cm above the floor, with and without a barrier to shield the patient's face. The accuracy of the cough simulation model and the relationship between patient-endoscopist vertical distance and endoscopist's facial exposure were evaluated. RESULTS:The flow dynamics of the cough simulation model were similar to that of an actual human cough. There was a significant inverse correlation between the patient-endoscopist vertical distance and the model endoscopist's facial exposure, with positive exposures decreasing from 87% at 70 cm to 0% at 100 cm (P < 0.001). The barrier device prevented facial exposure to droplets at all distances. CONCLUSIONS:We found that positioning the patient at least 100 cm below the top of the endoscopist's head or using a barrier device minimized the endoscopist's facial exposure to visible droplets during upper gastrointestinal endoscopy.

Project description:ImportanceThe COVID-19 pandemic is changing how health care providers practice. As some telemedicine and telecommunication support tools have been incorporated into the otolaryngology practice in response to safety and access demands, it is essential to review how these tools and services can help facilitate facial trauma evaluation during a time when clinical resources are limited.ObjectiveTo review applications of telemedicine for the evaluation of facial trauma to better direct utilization of these methods and technologies during times of limited access to clinical resources such as the COVID-19 pandemic.MethodsA systematic review was conducted using PubMed, Embase, and Web of Science.ResultsAfter screening 158 titles and abstracts, we identified 16 eligible studies involving facial trauma evaluation using telemedicine. Telemedicine opportunities for facial trauma evaluation have the potential to be developed in the areas of multidisciplinary remote consultations, facial trauma triage, patient engagement, and postoperative follow-up.ConclusionThe COVID-19 pandemic is posing obstacles for both providers and patients in the delivery of health care at a time of limited clinical resources. Telemedicine may provide a potential useful tool in the evaluation and triage of facial injuries and patient engagement.

Project description:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the current pandemic of coronavirus disease 2019 (COVID-19). This pandemic is characterized by a high variability in death rate (defined as the ratio between the number of deaths and the total number of infected people) across world countries. Several possible explanations have been proposed, but it is not clear whether this variability is due to a single predominant factor or instead to multiple causes. Here we addressed this issue using multivariable regression analysis to test the impact of the following factors: the hospital stress (defined as the ratio between the number of infected cases and the total number of hospital beds), the population median age, and the quality of the National Health System (NHS). For this analysis, we chose countries of the world with over 3000 infected cases as of April 1, 2020. Hospital stress was found to be the crucial factor in explaining the variability of death rate, while the others had negligible relevance. Different procedures for quantifying cases of infection and death for COVID-19 could affect the variability in death rate across countries. We therefore applied the same statistical approach to Italy, which is divided into 20 Regions that share the same protocol for counting the outcomes of this pandemic. Correlation between hospital stress and death rate was even stronger than that observed for countries of the world. Based on our findings and the historical trend for the availability of hospital beds, we propose guidelines for policy-makers to properly manage future pandemics.

Project description:We report data from an online experiment which allows us to study how generosity changed over a 6-day period during the initial explosive growth of the COVID-19 pandemic in Andalusia, Spain, while the country was under a strict lockdown. Participants (n = 969) could donate a fraction of a €100 prize to an unknown charity. Our data are particularly rich in the age distribution and we complement them with daily public information about COVID-19-related deaths, infections and hospital admissions. We find correlational evidence that donations decreased in the period under study, particularly among older individuals. Our analysis of the mechanisms behind the detected decrease in generosity suggests that expectations about others' behaviour, perceived mortality risk and (alarming) information play a key-but independent-role for behavioural adaptation. These results indicate that social behaviour is quickly adjusted in response to the pandemic environment, possibly reflecting some form of selective prosociality.
