BACKGROUND: Historically, chest radiographs (CXR) have been used to quickly diagnose pneumothorax (PTX) and hemothorax in trauma patients. Over the last 2 decades, chest ultrasound (CUS) as part of Extended Focused Assessment with Sonography in Trauma (eFAST) has also become accepted as a modality for the early diagnosis of PTX in trauma patients. METHODS: We queried our institution's trauma databases for all trauma team activations from 2021 for patients with eFAST results...

BACKGROUND: POCUS has become an integral part of the practice of emergency medicine. POCUS is a highly focused, limited, goal-directed exam with the expressed purpose of answering selected questions used at the bedside for critically ill patients who are not stable. We aimed to assess POCUS utilization and barriers by senior-year emergency medicine and critical care residents at two tertiary academic and referral hospitals in Addis Ababa, Ethiopia. Methodology . A cross-sectional study was conducted from June 1 to August 30, 2022 in St Paul's Hospital Millennium Medical College and Tikur Anbessa Specialized Hospital using an electronic survey of senior-year (second and third years) emergency medicine and critical care residents...

Water Sensitive Urban Design (WSUD) has attracted growing attention as a sustainable approach for mitigating pluvial flooding (also known as flash flooding), which is expected to increase in frequency and intensity under the impacts of climate change and urbanisation. However, spatial planning of WSUD is not an easy task, not only due to the complex urban environment, but also the fact that not all locations in the catchment are equally effective for flood mitigation. In this study, we developed a new WSUD spatial prioritisation framework that applies global sensitivity analysis (GSA) to identify priority subcatchments where WSUD implementation will be most effective for flood mitigation...

INTRODUCTION: There are currently no reports on whether telementoring for extended focused assessment with sonography for trauma (eFAST) improves critical care transport providers' performance in prehospital settings. Our objective was to determine the impact of teleguidance on eFAST performance and quantify workload experience. METHODS: Eight trauma injury modules were selected on simulated patients. Critical care transport (CCT) providers were tasked to complete one independent and one emergency physician-telementored eFAST...

Blunt trauma patients are often evaluated with extended focused assessment with sonography for trauma (eFAST). eFAST is a noninvasive, rapid, ultrasound-guided assessment for hemoperitoneum, pericardial effusion, and hemopneumothorax. Specificity and sensitivity are as high as 95% and 74%, respectively. Research suggests obesity confers increased morbidity and mortality and is an independent risk factor for trauma death. A previous study demonstrated that a BMI change from 36 to 40 changed the odds ratio for inaccurate eFAST from 1...

BACKGROUND: Trauma is the leading cause of death in India resulting in a significant public health burden. Indian Society of Critical Care Medicine (ISCCM) has established a trauma network committee to understand current practices and identify the gaps and challenges in trauma management in Indian settings. MATERIAL AND METHODS: An online survey-based, cross-sectional, descriptive study was conducted with high-priority research questions based on hospital profile, resource availability, and trauma management protocols...

STUDY OBJECTIVE: Developed to decrease unnecessary thoracic computed tomography use in adult blunt trauma patients, the National Emergency X-Radiography Utilization Study (NEXUS) Chest clinical decision instrument does not include the extended Focused Assessment with Sonography in Trauma (eFAST). We assessed whether eFAST improves the NEXUS Chest clinical decision instrument's diagnostic performance and may replace the chest radiograph (CXR) as a predictor variable. METHODS: We performed a secondary analysis of prospective data from 8 Level I trauma centers from 2011-2014...

INTRODUCTION: Point-of care-ultrasound (POCUS) has become ubiquitous in emergency medicine practice for the management of emergent pathophysiology. There is growing interest in its potential as a diagnostic tool in the prehospital setting. Few studies have examined the feasibility or efficacy of curricula targeted at teaching POCUS to prehospital personnel. Our objective in this study was to investigate a curriculum for the extended focused assessment with sonography in trauma (eFAST) exam in helicopter emergency medical services (HEMS) crews...

OBJECTIVE: Prehospital medicine has struggled to manage critical patients without the resources available to hospital-based teams. Point-of-care ultrasound could bridge this resource gap by providing critical insight into the pathology of trauma patients. This study aimed to determine if early positive extended focused assessment with sonography in trauma (eFAST) identification would lead to improved patient outcomes. METHODS: This is a prospective observational trial that took place from February 1, 2019, to August 13, 2021...

African swine fever (ASF) is an acute, hemorrhagic and severe infectious disease caused by the African swine fever virus (ASFV), and leads to a serious threat to the pig industry in China. Yet the impact of the virus in the environment and contaminated swill on the ASFV transmission is unclear in China. Then we build the ASFV transmission model with the virus in the environment and swill. We compute the basic reproduction number, and prove that the disease-free equilibrium is globally asymptotically stable when $ R_0 < 1 $ and the unique endemic equilibrium is globally asymptotically stable when $ R_0 > 1 $...

BACKGROUND AND OBJECTIVE: Providing trauma services demands high personnel resources and structural costs. The goal of this study was to show if the assignment of trauma patients to a defined A or B resuscitation room treatment as a modified management concept is safe and feasible. MATERIAL AND METHODS: Between May 2020 and January 2021, all resuscitation room trauma patients were included in this single center prospective observational study. All patients admitted to the resuscitation room underwent a classification according to the German S3 guidelines grade of recommendation GoR A and GoR B in polytrauma and the status of the ABCDE sequence to an A and B resuscitation room...

OBJECTIVE: This study attempts to replicate data from a similar study performed 5 years ago by comparing point-of-care (POCUS) extended focused abdominal sonography in trauma (eFAST) examinations performed by an air medical flight crew with those performed by a trauma team at a level 1 trauma center. METHODS: This prospective observational study evaluated 174 trauma patients over a 12-month period in southeastern Virginia and northeastern North Carolina. RESULTS: For 101 trauma patients who had a POCUS evaluation completed by the flight crews, a positive predictive value of 100% was obtained with a negative predictive value of 96...

A 22-year-old male presented following a precordial stab. He was haemodynamically and metabolically normal. Initial investigations did not reveal pericardial fluid or haemothorax. At diagnostic laparoscopy, we encountered haemoperitoneum and a diaphragmatic injury through which the heart was visible. After pericardial washout, laparoscopic repair was effected. This case highlights a potential problem with extended focused assessment with sonography in trauma (eFAST) in that it will only be positive if there is an accumulation of pericardial fluid...

INTRODUCTION: Chest trauma is one of the most important and commonest injuries that require timely diagnosis, accounting for 25-50% of trauma related deaths globally. Although CT scan is the gold standard for detection of haemothorax, it is only useful in stable patients, and remains unavailable in most hospitals in low income countries. Where available, it is very expensive. Sonography has been reported to have high accuracy and sensitivity in trauma diagnosis but is rarely used in trauma patients in low income settings in part due to lack of the sonography machines and lack of expertise among trauma care providers...

Accurate monitoring of forest carbon flux and its long-term response to meteorological factors is important. To accomplish this task, the model parameters need to be optimized with respect to in situ observations. In the present study, the extended Fourier amplitude sensitivity test (eFAST) method was used to optimize the sensitive ecophysiological parameters of the Biome BioGeochemical Cycles model. The model simulation was integrated from 2010 to 2020. The results showed that using the eFAST method quantitatively improved the model output...

BACKGROUND: Extended focused assessment with sonography for trauma (eFAST) is now an essential part of the primary survey of an emergency patient. The discrepancy between an increasing number of medical students and growing clinical commitments of lecturers is a major challenge in student teaching that needs to be resolved. The practice of using peers in the clinical education of medical students is a well-established tradition and commonly practiced but lacks definition in its implementation...

COVID-19 pandemic remains serious around the world and causes huge deaths and economic losses. To investigate the effect of vaccination and isolation delays on the transmission of COVID-19, we propose a mathematical model of COVID-19 transmission with vaccination and isolation delays. The basic reproduction number is computed, and the global dynamics of the model are proved.

Geological disposal of radioactive waste has been recognized as the 'reference solution' to ensure the safety required for the present and future society and environment. To study the possible exposure pathways from groundwater to humans, radioactive transport modelling is used. One of the ecosystems that may play a significant role when assessing the dose conversion factor (i.e. the dose resulting from a nominal release of 1 Bq/year of each radionuclide) for humans is forest. In this paper we have developed a model of a lake-farm system with a forest component...

The acceleration of urbanization and climate change has increasingly impacted the health level of urban dual water cycles. In order to accurately evaluate the health status of urban water cycles, the evaluation system covers four standard layers of water ecology, water abundance, water quality and water use, including 19 basic indicators such as water storage change and annual average precipitation. Three-scale AHP and EFAST algorithms are adopted to set the criterion and index layer weights. Water-cycle health assessment models are based on the improved TOPSIS model...
