ABSTRACT

In this study, to fundamentally solve the risk of cross-infection in screening centers responding to infectious diseases, a new non-contact screening center was developed that supplemented the problems of existing screening centers. Numerical analysis was performed on the effectiveness of a ventilation system to remove viral aerosols and prevent cross-infection. Moreover, full-scale field measurements and SF6 tracer gas simulating viral aerosol was used under the same conditions as it was for the numerical analysis, comparison, and verification when CFD simulations were performed. Currently, COVID-19 screening centers operating in Korea can be divided into five types;the risk of cross-infection is very high due to its structure where the movement of medical staff and suspected patients cannot be separated. As a result of the CFD simulation on the ventilation system of a non-contact screening center, among the 3,000 particles generated from a patient, not a single particle was transmitted from the specimen collection booth to the adjacent examination room. More than 99% of the particles were removed by the ventilation system after 559 seconds. As a result of the in-situ measurement, the concentration of SF6 gas generated in the specimen collection booth was effectively reduced by the ventilation system. Additionally, the SF6 gas was not detected in the examination room due to the maintenance of an appropriate differential pressure. © 2022, Architectural Institute of Korea. All rights reserved.

ABSTRACT

Objective. To describe the sociodemographic characteristics, comorbidity, and baseline functional status of patients aged 65 or older who came to hospital emergency departments (EDs) during the first wave of the COVID-19 pandemic, and to compare them with the findings for an earlier period to analyze factors of the index episode that were related to mortality. Methods. We studied data from the EDEN-COVID cohort (Emergency Department and Elder Needs During COVID-19) of patients aged 65 years or older treated in 40 Spanish EDs on 7 consecutive days. Nine sociodemographic variables, 18 comorbidities, and 7 function variables were registered and compared with the findings for the EDEN cohort of patients included with the same criteria and treated a year earlier in the same EDs . In-hospital mortality was calculated in the 2 cohorts and a multivariable logistic regression model was used to explore associated factors. Results. The EDEN-COVID cohort included 6806 patients with a median age of 78 years;49% were women. The pandemic cohort had a higher proportion of men, patients covered by the national health care system, patients brought from residential facilities, and patients who arrived in an ambulance equipped for advanced life support. Pandemic-cohort patients more often had diabetes mellitus, chronic kidney disease, and dementia;they less often had connective tissue and thromboembolic diseases. The Barthel and Charlson indices were worse in this period, and cognitive decline was more common. Fewer patients had a history of depression or falls. Eight hundred ninety these patients (13.1%) died, 122 of them in the ED (1.8%);these percentages were lower in the earlier EDEN cohort, at 3.1% and 0.5%, respectively. Independent sociodemographic factors associated with higher mortality were transport by ambulance, older age, male sex, and living in a residential facility. Mortalityassociated comorbidities were neoplasms, chronic kidney disease, and heart failure. The only function variable associated with mortality was the inability to walk independently. A history of falls in the past 6 months was a protective factor. Conclusions. The sociodemographic characteristics, comorbidity, and functional status of patients aged 65 years or older who were treated in hospital EDs during the pandemic differed in many ways from those usually seen in this older-age population. Mortality was higher than in the prepandemic period. Certain sociodemographic, comorbidity, and function variables were associated with in-hospital mortality. Copyright © 2022, Saned.

ABSTRACT

Hyperoxaluria can be primary due to defective glyoxylate metabolism leading to hepatic oxalate overproduction or secondary due to increased intestinal oxalate absorption. Oxalate nephropathy is the deposition of calcium oxalate crystals leading to tubular injury, interstitial fibrosis, and AKI or CKD. This describes three cases of renal oxalosis. First is a 60 year old male with stroke, hypertension, diabetes who presented with AKI of 4.5 mg/dL from 1.6 that rose to 11 mg/dL. Serologies for glomerulonephritis and paraproteinemia were negative. Biopsy showed tubular oxalate crystal deposition with tubular injury and interstitial nephritis. His renal failure required dialysis. Second is a 58 year old female with gastric bypass surgery who presented for edema and AKI from 1.3 to 3.6 mg/dL. Serologies were also negative. Biopsy showed interstitial nephritis with tubular calcium oxalate deposition. She was started on prednisone 60 mg. Creatinine stabilized to 2.2 mg/dL, not requiring dialysis. Third is a 82 year old male with obesity and sarcoma of the scalp treated with pembrolizumab who presented with dyspnea, edema and an AKI from 1 to 8.6 mg/dL. Urine sediment was bland with negative serologies. Differential included AIN due to pembrolizumab. Patient was started on high dose prednisone and biopsy showed interstitial nephritis and calcium oxalate crystal deposition. Patient endorsed taking frequent vitamin C as prophylaxis for Covid. Creatinine stabilized to 2.9 mg/dL not on dialysis. Classic etiologies of hyperoxaluria include dietary oxalate from ascorbic acid and fat malabsorption from gastric bypass surgery. Treatment includes increased fluid intake, oral calcium supplements and low oxalate diet. Oxalate nephropathy remains an under recognized cause of kidney failure, as such, early biopsy and intervention are necessary. (Figure Presented)

ABSTRACT

STATEMENT OF PROBLEM/QUESTION: Can establishing a return-bymail fecal immunochemical test (FIT) program increase the colorectal cancer screening rate in a safety net primary care clinic? DESCRIPTION OF PROGRAM/INTERVENTION: Colorectal cancer (CRC) screening rates are typically lower in safety net health systems. This trend has been exacerbated by the COVID-19 pandemic, which has limited access to colonoscopy for screening. There is evidence that FITs are costeffective and mailed FIT programs can increase screening rates for vulnerable patients. We implemented a return-by-mail FIT program in the adult primary care clinic of New York City Health + Hospitals/Bellevue, a public safety net hospital. We evaluated adults aged 50-75 who were not up to date with CRC screening. All patients due for CRC screening were only offered FIT as a screening modality. We implemented a partial mailed FIT program, in which FIT tests picked up in clinic could be returned by mail directly to the lab. Prior to our intervention, patients were required to return FITs to the clinic in person. MEASURES OF SUCCESS: We evaluated FIT completion rates within our clinic 30 days before and after the introduction of return-by-mail FIT kits in July 2021. We also evaluated our clinic's pre- and post-intervention performance relative to other clinics within the New York City Health + Hospitals system using claims data. Additionally, we randomly surveyed patients who received a FIT and did not complete it in the period prior to our intervention to assess reasons for incompletion. FINDINGS TO DATE: A total of 5,153 and 5,180 patients aged 50-75 were seen in clinic 30 days before and 30 days after the implementation of a mailed FIT program. 571 patients were provided a return-in-person FIT kit 30 days prior to our intervention. Of these patients, 289 (50.6%) completed a FIT. By contrast, 781 patients were provided a return- by-mail FIT kit 30 days following our intervention. Of these patients, 464 (59.4%) completed a FIT (p < 0.01). Additionally, the proportion of patients who completed annual CRC screening prior to our intervention was lower in our clinic (48.2%) compared to the average across the New York City public hospital system (51.4%) according to managed care Medicaid claims data (MetroPlus, June 2021). Four months following our intervention, our clinic's year-to-date CRC screening rate exceeded the average system-wide rate (59.3% vs. 57.6%, November 2021). We also called 45 patients who were provided a FIT test prior to our intervention and did not complete it. 12 patients were reached, and 2 of these patients cited difficulty dropping off the test as the primary barrier to FIT completion (16.7%). KEY LESSONS FOR DISSEMINATION: By implementing a return-bymail FIT program, we were able to increase our clinic's CRC screening rate by 8.8%. Our data are similar to previous programs implementing mailed FIT programs in safety net patient populations. Future aims are to implement a mail-to-patient FIT program in addition to our initial return-by-mail program.

ABSTRACT

Since the COVID 19 pandemic creates enormous casualties in the world, it rapidly changes the working environment. It significantly increased the virtual meeting among the team members at work. These require many pieces of equipment. Among the components, a webcam is becoming the most important piece of equipment in virtual meetings. Since the webcam becomes the important factor in the meeting, the attacks on the webcam are enormously increased. In many cases, when a group of hackers attacks a webcam, it creates critical privacy breaches. Therefore, to prevent these types of critical breaches, this paper closely conducts the Threat Modeling analysis based on DFD and STRIDE techniques on FireStormcx's webcam. Additionally, these types of Threat Modeling analysis result to create a recommended threat remediation plan.

ABSTRACT

The importance of disaster management and response is emerging as various disasters such as COVID-19, torrential rains, and fires occur one after another. In addition, in order to respond efficiently throughout disaster response activities, it is necessary to quickly collect disaster site information and quickly check the site situation through photo and video information so that rapid disaster response can be achieved. In this study, essential information required for decision-making was derived by analyzing the essential activities of each disaster response stage, analyzing the crisis management standard manual and related laws for each disaster type, and daily comprehensive report. In addition, a list of information necessary to grasp the situation of the disaster site and grasp the status of real-time damage was derived to establish guidelines for collecting volatile disaster site information, and disaster situation information can be efficiently displayed through a spatial information-based display system. By presenting essential disaster management information to be collected first, the person in charge of collecting information can efficiently collect information, and the situation room in charge of disaster response decision-making is expected to enable more efficient disaster situation management by receiving only the necessary information. © 2022 Korean Society of Surveying.

ABSTRACT

Background Colorectal cancer (CRC) screening rates are typically lower in public safety-net hospital systems, and optimal screening modalities have yet to be determined in this population. There is evidence that fecal immunochemical test (FIT) is a cost-effective approach in this setting, especially as the COVID-19 pandemic decreased the accessibility of colonoscopy. Mailed FIT outreach programs have been shown to markedly increased CRC screening for vulnerable patients. However, there is limited evidence regarding individual facets of these programs, such as returning FIT by mail. In the process of establishing a complete mailed FIT program during the pandemic, we evaluate the effect of allowing patients to mail back a completed FIT they received in person. Methods Patients at a safety-net hospital in New York City aged 50-75 who were not up to date with CRC screening were evaluated. We included patients 30 days before and after the implementation of mail-able FIT kits in July 2021. All patients due for CRC screening were only offered FIT as a screening modality, and prior to the intervention were required to visit the clinic to both obtain and return the FIT. We implemented a partial mailed FIT program, in which FITs picked up in clinic can be mailed directly to the lab after completion. We also randomly surveyed patients who received a FIT and did not complete it in the period prior to our intervention to assess reasons for incompletion. Results A total of 5,153 and 5,180 patients aged 50-75 were seen in clinic 30 days prior and 30 days after the implementation of the mail-able FIT kit respectively. A total of 571 patients were provided a FIT kit that required a return trip to the clinic for completion. Of these patients, 289 (50.6%) completed a FIT. In comparison, there were a total of 781 patients who were provided a FIT kit allowed to be mailed back for completion. Of these patients, 464 (59.4%) completed a FIT (p < 0.01). A total of 45 patients with an incomplete FIT prior to the intervention were called, and 12 patients were reached. Of these patients, 10 endorsed forgetting about the test, and 2 endorsed difficulty scheduling time to drop off the test. Conclusion Organized mailed FIT outreach was previously shown to improve CRC screening in a safety-net setting. We have further shown that implementing a program with FIT kits that can be mailed back significantly improves screening. While our mail-able kits would improve screening in patients with difficulty returning to clinic, many in our population would potentially benefit from reminders to complete. Future work could assess long-term completion rates of our program, and compare it with a full mailed FIT outreach program to quantify the potential increased benefit of also mailing kits to patients.

ABSTRACT

This paper proposes virtual reality content for non-face-to-face job education and job experience With the development of digital devices and communication technology, online communities are emerging, and people's lifestyles are also changing. Recently, due to COVID-19, telecommuting and online classes through video conferencing programs have been conducted, and they have also begun to be used for interviews. However, job training and hands-on activities other than classes after employment were mainly conducted offline, and virtual reality content was devised for non-face-to-face job education and job experience First, it was developed for the purpose of job experience, and content was produced under the theme of horticulture artists who are not well recognized as jobs but perform familiar tasks. It was configured similarly to the natural environment with the aim of rapid adaptation of users. In addition, heart rate data through heart rate sensors were used to induce intensive participation in the content of users and to elicit emotional stability.

ABSTRACT

This paper discusses the system for visual assistance assistant non-face-to-face activity assistance services to help blind and blind people with visual information during their daily lives. We would like to provide a limited number of helpers to help more people through non-face-to-face services. In addition, we would like to minimize the mutual anxiety between the blind and the helper in offline face-to-face activities due to pandemics such as COVID-19. The proposed system uses raspberry pie-based optician aids and WebRTC streaming technology to help visually impaired people check videos taken through aids in real time through streaming and translate videos. In addition, by allowing voice calls to be made so that visually impaired people can communicate well in situations where they ask for help, the visually impaired can only receive help at the moment they need it in real time. This is expected to contribute to the efficient use of time and manpower to assist more visually impaired people. As a follow-up study, we would like to study how the function of spectacle-type aids can be added to assist blind people in doing more activities independently.

ABSTRACT

Due to climate change coupled with the increase of zoonotic diseases, infectious diseases are more likely to occur and spread in the future;therefore, new alternatives and methods related to treatment environments should be considered. Under the global landscape of the prolonged COVID-19 pandemic, the number of patients who need to be cared for through negative isolation rooms is increasing. Consequently, it is essential to secure temporary medical facilities that can remain operational during a pandemic. These facilities must be safe and secured so that public confidence is increased, and treatment expedited. This study proposes a reference model and HVAC design criteria for mobile negative pressure isolation room modular systems to minimize cross-infection inside the health care space and ensure the safety of health care workers (HCWs) as well as securing rapid medical service supplies. The mobile negative pressure isolation room module basically reflects the one-way airflow direction from clean zone to dirty zone, and appropriate differential pressure control that separates the air environment between the HCW’s and the patient. If properly installed, the location of the exhaust air vents need to be directly above the patient’s bed, specifically on the wall near the head of the bed. The installation of the headboard on the patient’s bed as an exhaust air ventilation location was considered for infection prevention and control when performing aerosol-generating procedures (AGPs). © 2022 Architectural Institute of Korea.

ABSTRACT

Face recognition now requires a large number of labelled masked face images in the era of this unprecedented COVID-19 pandemic. Unfortunately, the rapid spread of the virus has left us little time to prepare for such dataset in the wild. To circumvent this issue, we present a 3D model-based approach called WearMask3D for augmenting face images of various poses to the masked face counterparts. Our method proceeds by first fitting a 3D morphable model on the input image, second overlaying the mask surface onto the face model and warping the respective mask texture, and last projecting the 3D mask back to 2D. The mask texture is adapted based on the brightness and resolution of the input image. By working in 3D, our method can produce more natural masked faces of diverse poses from a single mask texture. To compare precisely between different augmentation approaches, we have constructed a dataset comprising masked and unmasked faces with labels called MFW-mini. Experimental results demonstrate WearMask3D1produces more realistic masked faces, and utilizing these images for training leads to state-of-the-art recognition accuracy for masked faces. © 2021 IEEE
