Abstract

Thanks to the Grid, users have access to computing resources distributed all over the world. The Grid hides the complexity and the differences of its heterogeneous components. In such a distributed system, it is clearly very important that errors are detected as soon as possible, and that the procedure to solve them is well established. We focused on two of its main elements: the workload and the data management systems. We developed an application to investigate the efficiency of the different centres. Furthermore, our system can be used to categorize the most common error messages, and control their time evolution.

Abstract

SUMMARYAn inappropriate cross-connection between sewage- and drinking-water pipelines contaminated tap water in a Finnish town, resulting in an extensive waterborne gastroenteritis outbreak in this developed country. According to a database and a line-list, altogether 1222 subjects sought medical care as a result of this exposure. Seven pathogens were found in patient samples of those who sought treatment. To establish the true disease burden from this exposure, we undertook a population-based questionnaire investigation with a control population, infrequently used to study waterborne outbreaks. The study covered three areas, contaminated and uncontaminated parts of the town and a control town. An estimated 8453 residents fell ill during the outbreak, the excess number of illnesses being 6501. Attack rates were 53% [95% confidence interval (CI) 49·5–56·4] in the contaminated area, 15·6% (95% CI 13·1–18·5) in the uncontaminated area and 6·5% (95% CI 4·8–8·8) in the control population. Using a control population allowed us to differentiate baseline morbidity from the observed morbidity caused by the water contamination, thus enabling a more accurate estimate of the disease burden of this outbreak.

Abstract

In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC)[1] experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG[2]/EGEE[3], OSG[4], NDGF[5]) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications.

Abstract

The ARDA project aims to provide end-to-end systems for physics analysis for the LHC experiments. In collaboration with the experiments, prototype systems are being developed that are based on the experimental software and on the middleware under development within the EGEE project â" gLite. The strategy of the ATLAS experiment is to develop high level services that supports physics analysis and simplifies grid usage for the physicist. A first implementation of such a service, DIAL, has already been developed and interfaces to conventional batch systems such as LSF or Condor. In this report first experiences using ATLAS software with the gLite prototype are described. The integration of ATLAS software components with the prototype is discussed. Some aspects of job execution, data management, metadata and Software installation are considered. A first implementation of a DIAL service based on the middleware prototype is demonstrated.

Abstract

Objectives: To assess the occurrence, clinical picture, and triggering infections of reactive arthritis (ReA) associated with a large waterborne gastroenteritis outbreak. Methods: After an extensive sewage contamination of the water supply system, an estimated 8453 of the 30 016 inhabitants of the town of Nokia fell ill. General practitioners and occupational physicians were advised to refer any patients with suspicion of new ReA to rheumatological examination including faecal culture, human leucocyte antigen (HLA)-B27 and antibody tests for Campylobacter, Salmonella, and Yersinia. Results: Forty-five patients (33 females, 12 males) aged 16–77 years (median 53) were referred. ReA was diagnosed in 21, postinfectious arthralgia in 13, and other musculoskeletal conditions in 11 patients. HLA-B27 was positive in five out of 44 patients (11%). Of the 21 patients with ReA, possible triggering infections were observed in seven (33%), Campylobacter in four, Yersinia in three, and Salmonella in one, who also had Campylobacter infection. ReA was mild in all but one patient who presented with persistent Salmonella enterica serotype enteritidis infection. Conclusions: Taking into account the large population contaminated with potentially arthritogenic agents, the occurrence of ReA was rare and mild in character. [ABSTRACT FROM AUTHOR]

Abstract

Study Objective: Emergency practitioners use ultrasound-guided nerve blocks to alleviate pain. This study represents the largest registry of single-injection ultrasound-guided nerve blocks performed in an emergency department (ED) to date. We wished to assess the safety and pain score reductions associated with ED-performed ultrasound-guided nerve blocks. The main outcomes of interest were ultrasound-guided nerve block complication rates and change in patient-reported pain (0 to 10 on the VAS) pre and post ultrasound-guided nerve blocks. Other variables of interest were ultrasound-guided nerve block types and indications during the study period., Methods: This is a retrospective analysis of 420 emergency practitioner-performed ultrasound-guided nerve blocks through chart review over 1 year in the Highland ED. Four emergency physician abstractors reviewed all templated ultrasound-guided nerve block notes and nursing records over the study period. Inter-rater reliability was assessed using 10 randomly selected charts with 100% agreement for 70 key variables (Kappa=1, P<.001)., Results: Seventy-five unique emergency practitioners performed 420 ultrasound-guided nerve blocks. Ultrasound-guided nerve blocks were most often performed by emergency residents (61.9%), advanced practice practitioners (21.2%), ultrasound fellowship-trained faculty (8.3%), interns (3.6%), nonultrasound fellowship-trained faculty (3.3%), and not recorded (1.7%). One complication occurred during the study (arterial puncture recognized through syringe aspiration without further sequelae). Among the 261 ultrasound-guided nerve blocks with preblock and postblock pain scores, there was an improvement in postblock pain scores. The mean pain scores decreased from 7.4 to 2.8 after an ultrasound-guided nerve block (difference 4.6, 95% confidence interval 3.9 to 5.2)., Conclusions: This 1-year retrospective study supports that emergency practitioner-performed ultrasound-guided nerve blocks have a low complication rate and are associated with reduced pain., (Copyright © 2023 American College of Emergency Physicians.

Abstract

Objectives: Little is known about the recent status of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the U.S. emergency department (ED). This study aimed to describe the disease burden (visit and hospitalization rate) of AECOPD in the ED and to investigate factors associated with the disease burden of AECOPD., Methods: Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS), 2010-2018. Adult ED visits (aged 40 years or above) with AECOPD were identified using International Classification of Diseases codes. Analysis used descriptive statistics and multivariable logistic regression accounting for NHAMCS's complex survey design., Results: There were 1,366 adult AECOPD ED visits in the unweighted sample. Over the 9-year study period, there were an estimated 7,508,000 ED visits for AECOPD, and the proportion of AECOPD visits in the entire ED population remained stable at approximately 14 per 1,000 visits. The mean age of these AECOPD visits was 66 years, and 42% were men. Medicare or Medicaid insurance, presentation in non-summer seasons, the Midwest and South regions (vs. Northeast), and arrival by ambulance were independently associated with a higher visit rate of AECOPD, whereas non-Hispanic black or Hispanic race/ethnicity (vs. non-Hispanic white) was associated with a lower visit rate of AECOPD. The proportion of AECOPD visits that were hospitalized decreased from 51% to 2010 to 31% in 2018 (p = 0.002). Arrival by ambulance was independently associated with a higher hospitalization rate, whereas the South and West regions (vs. Northeast) were independently associated with a lower hospitalization rate. The use of antibiotics appeared to be stable over time, but the use of systemic corticosteroids appeared to increase with near statistical significance (p = 0.07)., Conclusions: The number of ED visits for AECOPD remained high; however, hospitalizations for AECOPD appeared to decrease over time. Some patients were disproportionately affected by AECOPD, and certain patient and ED factors were associated with hospitalizations. The reasons for decreased ED admissions for AECOPD deserve further investigation., (© 2023. The Author(s).)

Abstract

Little is known about pulmonary embolism (PE) in the United States emergency department (ED). This study aimed to describe the disease burden (visit rate and hospitalization) of PE in the ED and to investigate factors associated with its burden. Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2018. Adult ED visits with PE were identified using the International Classification of Diseases codes. Analyses used descriptive statistics and multivariable logistic regression accounting for the NHAMCS's complex survey design. Over the 9-year study period, there were an estimated 1,500,000 ED visits for PE, and the proportion of PE visits in the entire ED population increased from 0.1% in 2010-2012 to 0.2% in 2017-2018 (P for trend = 0.002). The mean age was 57 years, and 40% were men. Older age, obesity, history of cancer, and history of venous thromboembolism were independently associated with a higher proportion of PE, whereas the Midwest region was associated with a lower proportion of PE. The utilization of chest computed tomography (CT) scan appeared stable, which was performed in approximately 43% of the visits. About 66% of PE visits were hospitalized, and the trend remained stable. Male sex, arrival during the morning shift, and higher triage levels were independently associated with a higher hospitalization rate, whereas the fall and winter months were independently associated with a lower hospitalization rate. Approximately 8.8% of PE patients were discharged with direct-acting oral anticoagulants. The ED visits for PE continued to increase despite the stable trend in CT use, suggesting a combination of prevalent and incident PE cases in the ED. Hospitalization for PE remains common practice. Some patients are disproportionately affected by PE, and certain patient and hospital factors are associated with hospitalization decisions., (© 2023. The Author(s).)

Abstract

Introduction: Although factors related to a return visit to the emergency department (ED) have been reported, only a few studies have examined "high-risk" ED revisits with serious adverse outcomes. In this study we aimed to describe the incidence and trend of high-risk ED revisits in United States EDs and to investigate factors associated with these revisits., Methods: We obtained data from the National Hospital Ambulatory Medical Care Survey (NHAMCS), 2010-2018. Adult ED revisits within 72 hours of a previous discharge were identified using a mark on the patient record form. We defined high-risk revisits as revisits with serious adverse outcomes, including intensive care unit admissions, emergency surgery, cardiac catheterization, or cardiopulmonary resuscitation (CPR) during the return visit. We performed analyses using descriptive statistics and multivariable logistic regression, accounting for NHAMCS's complex survey design., Results: Over the nine-year study period, there were an estimated 37,700,000 revisits, and the proportion of revisits in the entire ED population decreased slightly from 5.1% in 2010 to 4.5% in 2018 (P for trend = 0.02). By contrast, there were an estimated 827,000 high-risk ED revisits, and the proportion of high-risk revisits in the entire ED population remained stable at approximately 0.1%. The mean age of these high-risk revisit patients was 57 years, and 43% were men. Approximately 6% of the patients were intubated, and 13% received CPR. Most of them were hospitalized, and 2% died in the ED. Multivariable analysis showed that older age (65+ years), Hispanic ethnicity, daytime visits, and arrival by ambulance during the revisit were independent predictors of high-risk revisits., Conclusion: High-risk revisits accounted for a relatively small fraction (0.1%) of ED visits. Over the period of the NHAMCS survey between 2010-2018, this fraction remained stable. We identified factors during the return visit that could be used to label high-risk revisits for timely intervention.

Abstract

Bedside ultrasound has been shown to change and direct patient management in the emergent setting. Demand, use, and diagnostic potential of point-of-care ultrasound (POCUS) has continually increased throughout the years. The ongoing COVID-19 pandemic and physical distancing have necessitated further POCUS innovation. With the advent of affordable portable ultrasound devices, teleultrasound teaching has become a more viable method of POCUS education, especially in resource-limited settings. Here, we provide a scoping review of the current state of teleultrasound, specifically its use for educational purposes., (© 2021 American Institute of Ultrasound in Medicine.)

Abstract

Background: Schizophrenia is a serious mental illness requiring self-management skills and information about the illness, its treatment, and where to get help with daily routines. Despite the systematic development of computer-based approaches in mental health, less systematic development of such methods can be found for patients with schizophrenia or psychosis., Objective: The aim is to describe the design and development process of patient-centered computer-based support system (Mieli.Net portal) for patients with schizophrenia spectrum psychoses., Methods: The process with a mixed methods approach includes four phases: analysis of users' needs, development of key patient information areas, development of a software prototype and to pilot the portal, and user evaluation by health care staff., Results: The computer-based patient support system is a promising health-promoting service to schizophrenic patients. It is important, that users of technology are involved in the development process, which will ensure that sites are user-friendly, information can be personalized, and mental patients' voices are heard in the development of patient education., Conclusions: The effectiveness needs to be evaluated carefully in future clinical trials. This will offer valuable information for policymakers, organizations and health care practitioners about the usability of web-based patient education in the area of mental health care.
