ABSTRACT

Introduction: Venous thrombo-embolism (VTE) disease in critically ill COVID-19 patients is a remarkable issue, especially its relationship with bleeding events and mortality. The objective of this study was to describe the outcomes of critically ill patients with COVID-19 hospitalised in the intensive care unit (ICU) in relationship with VTE during their stay. The secondary objective was to describe prognostic factors in relation with these outcomes. Methods: This was a prospective cohort study of critically ill COVID-19 patients in two Spanish university hospitals that underwent, at the beginning of the study, venous ultrasound of both lower limbs in April 2020. When there was clinical suspicion of new VTE during the 30 day follow up, additional ultrasound or thoracic computed tomography were performed. Global VTE frequency, major bleeding events, and survival were collected, and their predictors were studied. Results: In total, 230 patients were included. Mean age was 60.1 ± 9.9 years and 77% of them were men. After 30 days of follow up, there were 95 VTE events in 86 patients (37.4%). Of these, 60 patients (69.8%) presented with deep vein thrombosis (DVT), 17 patients with pulmonary embolism (PE;19.8%), and nine patients with DVT and PE (10.5%). VTE was related to a longer hospital stay: 50.3 days in VTE patients and 47.2 days in non-VTE patients (p =.014). D-dimer at admission was significantly related to VTE development (p =.007). Major bleeding complications were found in 13 patients (5.7%). None of the demographic variables, treatments, or classic risk factors were related to a higher risk of major bleeding. During the 30 day follow up, 42 patients (18.3%) died. Variables related to mortality were older age (67.4 vs. 58.4 years;p <.001), lower weight (77.9 vs. 87.5 kg;p <.001), lower body mass index (28.2 vs. 30,8 kg/m2;p =.006), hypertension (43.1% vs. 69% of patients;p =.002), lymphocyte count at admission < 0.45 ×109/L (p =.003) and D-dimer at admission > 1 500 ng/mL (p =.014). Patients with VTE at any moment during the follow up tended to die more frequently (50%) than non-VTE patients (34.6%), but this difference was not statistically significant (p =.062). Independent predictors of mortality in the regression model were older age (> 66 years), D-dimer at admission (> 1 500 ng/mL), and low lymphocyte count (< 0.45 ×109/L) with an area under the receiver operating curve of 0.81 (95% confidence interval 0.73 – 0.89). Patients presenting these three conditions presented a mortality of a 100% in the predictive model. Conclusion: VTE frequency in ICU COVID-19 patients is high and the risk of major bleeding is low. Comorbidities and laboratory parameters of admission in these patients can be a useful tool to predict mortality.

ABSTRACT

STATEMENT OF PROBLEM/QUESTION: Social risk factors (SRF), such as food insecurity, represent adverse social circumstances associated with poor health outcomes. The COVID-19 pandemic impacted impoverished communities by exacerbating existing SRF. Students and faculty at Boston University Medical Center (BUMC), an academic safety net hospital, and Boston University School of Social Work (BUSSW) partnered to develop an outreach call center (CC) to explore SRF of patients with COVID-19 and connect them with available social need resources. In this , the development and operations of the CC and descriptive data on the volume and type of outreach efforts will be presented. DESCRIPTION OF PROGRAM/INTERVENTION: Call Center (CC) Operation: An ambulatory RN performed SRF screening in patients diagnosed with COVID-19 and sent referrals to the CC. Then, students called patients and screened for SRF using the THRIVE screening tool, and used the THRIVE Directory, an online repository of resources, to provide information about organizations to support their social needs. Two weeks later, students called the patients to assess whether they received help and provided additional support as needed. MEASURES OF SUCCESS: Volume of outreach calls and type of outreach efforts were evaluated. Number of patients reached through the CC were tracked using Epic reports. Types of referrals were tracked using automated reports from the THRIVE Directory database. Finally, students completed surveys to reflect on their experiences and to evaluate the impact on skills to address social needs. FINDINGS TO DATE: Between 10/2020 and 03/2021, the CC served 312 patients and 478 referrals were made, with a mean of 1.53 referrals per patient. Patients were most often referred to the City of Boston Food Delivery (148 referrals). Patients were most often referred to Government programs (188), followed by BMC programs (133) and Local Non-Profits (70). The most common primary support area was Food. Preliminary results from students' surveys showed a positive impact in their skills to collaboratively address social needs. KEY LESSONS FOR DISSEMINATION: It was feasible to develop and implement an interdisciplinary social needs outreach workforce to support patients with COVID-19. Food was the most important driver of social need among BUMC patients. Our partnership with the City of Boston was key to effective assistance with food delivery, showing the importance of collaborative partnerships when developing outreach efforts to support patients with social needs. Finally, interdisciplinary outreach opportunities like the CC can be used to teach health professional students about the different scopes of practice and how to effectively collaborate with other disciplines when addressing patient health related social needs.

ABSTRACT

Affective computing is an emerging research area focused on the development of devices and systems that have the ability to recognize, interpret, process and simulate human emotions in order to improve a user's experience when interacting with a software system. One of the possible fields of application of the techniques provided by affective computing is in the design and generation of multimedia content in the context of formal and non-formal education, which can generate greater interest in students through the transmission of different emotions throughout this content. Based on the above, in this article, an analysis of emotions is carried out on a set of content provided by the Ministry of Health of Colombia as a measure for the prevention and mitigation of contagion by COVID-19. For the development of the study, a tool has been built in the Java language, which allows the segmentation of the audio fragments of the multimedia content, as well as the extraction of the acoustic parameters of arousal and valence, and the application of clustering models on the set of properties extracted from the segments.

ABSTRACT

Background: The COVID-19 pandemic introduced unprecedented disruptions to healthcare delivery, particularly for ambulatory services such as gastrointestinal endoscopy. At the peak of the pandemic in our region between December 2020 to February 2021, ambulatory endoscopy services were suspended at the Los Angeles County + University of Southern California Medical Center (LAC+USC). While endoscopy services resumed in March 2021, the operational challenges introduced by COVID-19 led to a mounting backlog of patients awaiting endoscopic procedures reaching 1,035 by June 2021. As part of our solution to this crisis, we used the principles of operations management to perform a process flow analysis to identify inefficiencies and develop targeted interventions to enhance the operational performance of our endoscopy unit. Methods: A time-motion analysis of patient flow through the LAC+USC Endoscopy Unit was used to construct a comprehensive time-tracked flow sheet to track individual patients as they moved through the unit from check-in to discharge on random dates over a 6-week period (Figure 1). Simultaneously, a qualitative stakeholder survey on perceived operational inefficiencies was distributed to all faculty, staff, and fellows in the endoscopy unit. At the end of 6 weeks, collected data were compared to both published benchmarks and stakeholder survey responses, and inefficiencies identified for intervention. Results: Data were collected for 214 procedures (179 moderate sedation, 35 monitored anesthesia care) in the endoscopy unit. When compared to established benchmarks, we found operational delays in 1) check-in to procedure start time, 2) room turnover time, and 3) first-case on-time start percentage (Table 1). Results from the stakeholder survey aligned with these data. Targeted interventions (Table 1) developed by a multi-disciplinary group of faculty, nursing staff, and trainees from both Gastroenterology and Anesthesiology departments were then implemented, including 1) preparation of the first patient of the day in the procedure room, 2) pre-operative clinic visits for all patients designated to require anesthesia during endoscopy, 3) implementation of a brief-operative note and 4) a time study to encourage first-case on-time start. In combination with maneuvers to streamline the pre-procedure process, this resulted in a reduction of the backlog to 430 by November 2021. Conclusion: Granular analysis of data tracking process flow times through the LAC+USC Endoscopy Unit aligned with stakeholder perceptions regarding operational inefficiencies. The combination of objective and subjective data allowed us to rapidly implement targeted interventions to increase the throughput of the endoscopy unit and address the backlog of endoscopy procedures caused by the COVID-19 pandemic.

ABSTRACT

The pandemic brought businesses to a standstill, and the luxury sector was no exception. In order to survive, business activities are digitalizing fast, but the question is whether this direction is suitable for luxury – an industry that needs to preserve exclusiveness as well as direct human contact. This study proposes the application of the “online customer engagement cycle” model to luxury businesses, to bring about the most effective way to strengthen and manage customer activities when digitizing, thereby supporting luxury brands to stand firm and set a foundation for post-pandemic success. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Patient care in emergency rooms can utilize urgency labeling to facilitate resource allocation. With COVID-19 care, one of the most important indicators of care urgency is the severity of respiratory illness. We present an early analysis of 5,584 patient records, of whom 5,371 (96.2%) have returned a positive COVID-19 test, to understand how well we can predict the severity of a respiratory illness given other features describing a patient using Deep Learning methods. The goal of our work is to illustrate the connection of our COVID-19 patient dataset with Deep Learning techniques, setting the stage for future work. The features in our dataset include when COVID-19 symptoms began, age, height, weight, demographics, and pre-existing conditions, to give a quick preview. We report train-test performance of a Deep Multi-Layer Perceptron (MLP) to predict the severity of respiratory analysis on a one-hot encoded scale of 5 labels. This 5-level scale is a truncation of our available labels, which we plan to extend and include in future work. We utilize a high-level of Dropout in order to avoid overfitting with our Deep Learning model. Further, we particularly study the impact of class imbalance on this dataset (Johnson and Khoshgoftaar 2019). We find that Random Oversampling (ROS) is an effective solution for decreasing minority class false negatives, as well as increasing overall accuracy. Readers will understand the performance of Deep Learning, with Dropout and ROS, to predict the severity of a COVID-19 pa-tient’s respiratory illness in which patients are described with Tabular Electronic Health Records (EHR). © 2022 by the authors.

ABSTRACT

On March 14, 2020, a state of alarm was decreed in Spain, including restrictive mobility and economic activity measures. These restrictions caused changes in life habits, entertainment, and media consumption. The constant need for information promoted television as a trusted channel to bring current affairs closer to citizens. The interruption of programming with news flashes marked the program schedule and triggered TV consumption, especially during strict lockdown. There was a drop in television advertising investment of -18.4 % compared to 2019 and -50 % in April and May. Two reasons can explain the increase in TV consumption: the need for information on the epidemiological context and the increased time that citizens spent in their residence due to mobility restrictions. The first point can be contrasted with the significant increase in the audience of newscasts and the second with the correlation between citizens’ consumption and mobility. This analysis makes it possible to predict TV consumption based on mobility and design better media planning strategies tailored to the possible scenarios caused by COVID-19. © 2022 Universidad de La Sabana.

ABSTRACT

OBJECTIVE: The nursing homes represented high-risk settings for SARS-CoV-2 infection, both for residents and for the employees. The COVID-19 impact on long-term care facilities (LTCFs) is evaluated, measured through the employees sick leave (SL). The pandemic evolution in the general population aged between 16 and 65 years was analyzed together with the sick leave to assess the latter as a complementary indicator of the SARS-CoV-2 surveillance. METHODS: A descriptive study of all sick leave processes due to COVID-19 recorded between February 15th 2020 and May 1st 2021 in nursing homes was carried out. The close contact sick leave/infection sick leave ratios, the 100,000 affiliated/occupied sick leave rates were computed and compared with the COVID-19 cases cumulative incidence notified to the National Network of epidemiological Surveillance (RENAVE). RESULTS: 261.892 SL processes were recorded. The close contact sick leave/infection sick leave median ratio in nursing homes was 1.8 (Interquartile range, ICR: 1.1-3.3), with values lower than 1 at certain periods. The infection sick leaves were higher in number and ratio and prior to the cases recorded in RENAVE. The sick leave ratio ranged between 81.679/100.000 occupied in nursing homes with medical care and 4.895/100.000 in other residential facilities. CONCLUSIONS: The results confirmed the dramatic impact of COVID-19 in nursing homes and the inequalities characterizing this impact. They also confirmed the potential use of sick leave as an alternative source for epidemiological and public health surveillance, especially now, when the transition of the COVID-19 surveillance to a system not including universal individual surveillance is being discussed.

ABSTRACT

Universities must develop disciplinary skills during the COVID-19 era due to virtual classes, even in laboratory practices. In this experiment, disciplinary skills during COVID-19 era are developed through Project-Based Learning (PjBL), which is a classroom approach to give students knowledge and skills, through projects focused on real world challenges and problems. The purpose of this study was to design PjBL using Internet of Things (IoT) to have quantitative evaluation, learning experience perception, course contents assimilation, perception of improvement in soft skills and critical thinking. The project consisted in the measurement and analysis of vehicle variables for an engine embedded in IoT with idle speed conditions. The vehicle variables to be measured and analyzed are: carbon oxide and dioxide gas emissions, gas emission temperature, engine bay temperature and humidity, engine RPM, oil temperature, engine inertial forces, engine block temperature, and accelerator pedal position. The results prove that PjBLs with IoT in a hybrid context improve the students' learning experiences in a similar way to the face-to-face context. The score grade before and during COVID-19 exhibited 1.59% of increment;the learning experience perception showed that the students preferred the hybrid (42.86%) model (remote and real) in similar percentage in comparison with the face-to-face (53.06%), the virtual model (remote) was not fully accepted (4.08%). The 81.6% of the students preferred to implement projects based on IoT for future courses or prototypes. © 2021 ACM.

ABSTRACT

BACKGROUND AND OBJECTIVES: Since the COVID-19 pandemic confinement was established in Spain on March 9, 2020, the number of visits to the pediatric Emergency Department (ED) has decreased dramatically, probably due to the fear of parents becoming infected in the hospital environment. The aim of this work was to analyze the medium-term consequences during the first 9 months after the onset of the COVID-19 pandemic in children with acute appendicitis (AA). MATERIAL AND METHODS: A retrospective study was performed on children operated on for AA in our institution between 2017 and 2020, who were distributed in two groups according to the date of surgery: COVID-19 group (after March 9, 2020) and control group (before March 9, 2020). Demographic variables, associated symptoms, time from symptoms onset, hospital stay, rate of complicated AA and postoperative complications were analyzed. RESULTS: A total of 1274 patients were included (288 COVID group; 986 control group), without demographic differences. Time from symptom onset was significantly longer in COVID-19 group (34.5 vs. 24.2h; p=0.021), although no differences in associated symptoms were observed between both groups. COVID-19 group presented a higher rate of complicated AA (20.1% vs. 14%; OR: 1.55; CI 95% [1.10-2.18]; p=0.008), a longer hospital stay (3.5 vs. 2.8 days; p=0.042) as well as a higher rate of postoperative complications (21.5% vs. 15.7%; OR: 1.47; CI 95% [(1.06-2.04)]; p=0.008). CONCLUSION: In our experience there was a negative medium-term effects of the COVID-19 pandemic on children with acute appendicitis: delayed ED visits, increased rate of complicated AA, increased hospital stay and increased postoperative complications.

ABSTRACT

OBJECTIVE: To establish whether there is clinical improvement with the administration of chloroquine as outpatient treatment in patients suspected of COVID-19 assessed by the reduction of clinical manifestations associated with viral infection. MATERIALS AND METHODS: An experimental study was made in patients suspected of COVID-19 who were attended in the respiratory emergency service of the Hospital Juárez de México from June 1st to July 30th, 2020, who received outpatient treatment with chloroquine. The patients were followed up by telephone to find out their health condition. RESULTS: Fifty patients were included, of which 36 were female. The mean age was 41.1 year;the most frequent symptoms were fever, cough and odynophagia;the most persistent symptom was cough (31 out of 50). Also, 24 patients were positive for SARS-CoV-2 and completed their treatment with chloroquine, with persistent descricough;diarrhea, dysgeusia, and symptoms such as nausea, hypogeusia and headache were documented. No patient required a second evaluation in the emergency room or hospital admissions. CONCLUSIONS: Clinical evidence suggests that chloroquine may be useful in reducing the symptoms associated with SARS-CoV-2 if it is administered in the first five days of the onset of the disease;controlled studies are required to confirm this possibility.

ABSTRACT

The new current pandemic situation has meant that some previously unknown concepts have become part of our everyday language, as is the case with health areas. These are the demarcations for the distribution of health services, and their boundaries depend on broad criteria such as demographic, geographic, labor, epidemiological, road provisioning, or health facilities within them. But, from a planning perspective, what could be the minimum unit of confinement? What would be their characteristics and minimum services? What would be the appropriate criteria to define these units? The very experience lived during this pandemic, makes us reflect and put on the table the debate on the policies and action plans determined by the different governments from the perspective of the praxis of urbanism. From this experience, this study aims to reflect, from the perspective of urban planning, on the potential criteria best suited to the definition of minimum units of social confinement that can be included in the processes of urban planning and management. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
