ABSTRACT

Introduction: Over the past decade, through numerous technical advances and clinical studies, cardiovascular computed tomography (CCT) has gained increasing acceptance;recently evidenced by receiving multiple class 1, level A recommendations in the 2021 AHA/ACC Chest Pain Guidelines. We aimed to evaluate recent CCT practice and practitioner trends in the US Medicare population with the motivation of guiding practice, training, and advocacy. Methods: A retrospective cross-sectional analysis of Medicare Part B pay-for-service physician payments was performed between 2013-2020. CCT/FFRCT exams and providers were identified by unique HCPCS codes. Providers, exams, cost, and payment denials were analyzed. Medical specialty, gender, and geo-location of providers were summarized. Results: From 2013 to 2019, the number of providers of CCT exams and the number of exams increased significantly. Providers of CAC scoring increased >210%. Providers of coronary CTA in the hospital setting increased 36% and in independent testing facilities by 9%. CAC scoring exams increased 724% and coronary CTA exams increased 126% (see Figure). In the first year of the COVID-19 pandemic (2020), CAC scoring usage decreased by -9.3% and coronary CTA by -3.3%. Since initial reimbursement in 2018, FFRCT usage has increased by 654% but was applied in only 4% of coronary CTA exams. In 2020, contrary to a moderate CCT exam decline, FFRCT analysis increased by 376% compared to the previous year. Medicare insurance acceptance of cardiac CT became more favorable into 2020 (see Figure). CAC scoring denials decreased from 61.6% to 33.2% and coronary CTA denials decreased slightly from 7.3% to 6.4%. FFRCT denials decreased significantly from 64% to 6%. In 2019, 30.5% of CCT providers were cardiologists with the remainder being predominantly radiologists. On the other hand, 76.2% of FFRCT providers were cardiologists. A slightly lower percentage of FFRCT billing physicians were female compared to CCT billing physicians (14.2% vs 17.9%). CA, NY, MN, TX, and PA had the highest FFRCT utilization. Conclusions: In general, both CAC scoring and coronary CTA utilization have increased, along with a large increase in the utilization of FFRCT over the study time period. This increase in utilization was accompanied by a significant increase in providers and a decrease in reimbursement denials. In the first year of the COVID-19 pandemic, CCT usage was robust and only decreased moderately. [Formula presented]

ABSTRACT

Coronavirus (COVID-19 or SARS-CoV-2) is a novel viral infection that started in December 2019 and has erupted rapidly in more than 150 countries. The rapid spread of COVID-19 has caused a global health emergency and resulted in governments imposing lock-downs to stop its transmission. There is a significant increase in the number of patients infected, resulting in a lack of test resources and kits in most countries. To overcome this panicked state of affairs, researchers are looking forward to some effective solutions to overcome this situa-tion: one of the most common and effective methods is to examine the X-radiation (X-rays) and computed tomography (CT) images for detection of Covid-19. How-ever, this method burdens the radiologist to examine each report. Therefore, to reduce the burden on the radiologist, an effective, robust and reliable detection system has been developed, which may assist the radiologist and medical specia-list in effective detecting of COVID. We proposed a deep learning approach that uses readily available chest radio-graphs (chest X-rays) to diagnose COVID-19 cases. The proposed approach applied transfer learning to the Deep Convolutional Neural Network (DCNN) model, Inception-v4, for the automatic detection of COVID-19 infection from chest X-rays images. The dataset used in this study contains 1504 chest X-ray images, 504 images of COVID-19 infection, and 1000 normal images obtained from publicly available medical repositories. The results showed that the proposed approach detected COVID-19 infection with an overall accuracy of 99.63%. © 2023, Tech Science Press. All rights reserved.

ABSTRACT

COVID-19 has caused a global health crisis that has infected millions of people across the globe. Currently, the fourth wave of COVID-19 is about to be declared as Omicron. The new variant of COVID-19 has caused an unprecedented increase in cases. According to World Health Organization, safety measures must be adopted in public places to prevent the spread of the virus. One effective safety measure is to wear face masks in crowded places. To create a safe environment, government agencies adopt strict rules to ensure adherence to safety measures. However, it is difficult to manually analyze the crowded scenes and identify people violating the safety measures. This paper proposed an automated approach based on a deep learning framework that automatically analyses the complex scenes and identifies people with face masks or without facemasks. The proposed framework consists of two sequential parts. In the first part, we generate scale aware proposal to cover scale variations, and in the second part, the framework classifies each proposal. We evaluate the performance of the proposed framework on a challenging benchmark data set. We demonstrate that the proposed framework achieves high performance and outperforms other reference methods by a considerable margin from experimental results. © 2022, IFIP International Federation for Information Processing.

ABSTRACT

This research aimed to investigate the impact of electronic word-of-mouth (eWOM) in measuring the service quality of the recreational vehicle tourism industry in New Zealand. SERVQUAL model was employed to measure the service quality among RV rental service providers (Maui and Mighty) in New Zealand. Data was collected from the websites of Maui and Mighty which belong to Tourism Holdings Ltd (thl). A quantitative research approach was adopted to analyze the demographic features of the customers. The study analyzed 461 online customer reviews using qualitative method to measure RV tourism service quality in New Zealand. Findings showed that reviews were more about the tangible factors of the services and were most frequently coded and represented 60.4 percent of the total. Nearly 70 percent of reviews were positive about the services of RV tourism industry. This study revealed that eWOM could conclusively indicate the service quality from direct customer feedback. eWOM would benefit customers, business managers, and tourism industry. This study was conducted in February 2020 just before the COVID-19 pandemic so this gave us an opportunity to analyze the customers' reviews during lockdown period. Further research is necessary to ascertain the impact of eWOM on recreational vehicle tourism industry after COVID-19.

ABSTRACT

The study aims to investigate the intrinsic motivation among L2 in their uses of digital learning platforms during the Covid-19 pandemic. In particular, the central questions in the study are to identify the profiles of intrinsic motivation among L2 learners using digital learning platforms, determine gender differences using digital learning platforms, investigate the difference in motivation according to students' performances, and describe the perceived enjoyment of using digital learning platforms. The study that used a questionnaire to collect data among 72 engineering students found positive intrinsic motivation utilizing the medium to learn English. However, there was insufficient evidence to show a difference between gender using the digital learning platforms with intrinsic motivation. There was also insufficient evidence to prove that grades are associated with students' intrinsic motivation when the teacher assigned synchronous or asynchronous classroom tasks. Yet, the present study found that publishing works in Canva and writing posts on LinkedIn were among the students' most preferred digital learning platforms activities. The study is significant to teachers since it assists them in managing classes and discovering the uses of digital learning platforms for a conducive learning atmosphere during the pandemic. It is recommended that teachers need to be creative in using digital learning platforms to promote collaborative learning among learners.

ABSTRACT

Face masks have been shown to slow or stop the spread of airborne COVID-19 droplets and aerosols. There is an apparent lack of research examining the effect of different types of masks used at the same time, and their impact on the spread of viral particles in a spatial sense. We introduce a rapid prototype model to overcome the issues in the available research using the Cell-DEVS formalism. We also build scenarios for the model to examine the effectiveness of all types of masks and respirators recommended by the World Health Organization on the spread of viral particles in an indoor environment. © 2021 IEEE.

ABSTRACT

Objective: The objective of the study was to investigate the knowledge, attitude and practice (KAP) re-garding novel coronavirus disease 2019 (COVID-19) among healthcare workers in Karachi Pakistan. Methods: This was a cross-sectional study conducted at medical unit 3, Jinnah Postgraduate Medical Centre, Karachi by using a self-reported questionnaire-based survey from March 2020 to May 2020. A convenience sampling technique was used to recruit the consenting HCWs of all categories (doctors, nurses, pharmacists and technicians) who were currently providing services at different hospitals of Karachi. The non-consenting and unavailable doctors were excluded from this study. The questionnaire was developed by using the frequently asked questions from the WHO and Centre for Disease Control (CDC). The healthcare workers knowledge, attitude and practices related to COVID-19 were used as outcomes. Healthcare workers were approached by investigators and survey instrument was made accessible through a link on social media (WhatsApp, Facebook, and emails). Binary logistic regression analysis was performed to estimate the odds ratio with 95% confidence interval for KAP of HCWs regarding COVID-19. P-values less than 0.05 were considered statistically significant. Results: A total of 553 subjects completed the study questionnaire. However, data of 547 (98.9%) par-ticipants was selected for inclusion in final analysis after excluding 6 respondents. HCWs gross category and clinical setting were found to be statistically associated with overall KAP (P<0.001 and P=0.048, respectively). Upon logistic regression analysis, KAP scores statistically differed across genders (p coefficient=2.115, SE =0.179 and P<0.001), age groups (p coefficient=2.098, SE =0.138 and P<0.001) and HCWs gross category (p coefficient=2.053, SE=0.135 and P<0.001). The nurses and technicians were found less likely for good KAP with reference to COVID-19 as compared to doctors and pharmacists. These results were found to be statistically significant with P-value less than 0.05;the odds for nurses and technicians were 0.35 and 0.10, respectively. Conclusion: The study demonstrated that HCWs had good knowledge, optimistic attitude and decent practice towards recent COVID-19 pandemic. However, their source of information regarding COVID-19 is not reliable and can adversely influence the KAP.

ABSTRACT

Presently the worldwide lockdown from Covid-19 give a huge effect on different sectors across the board, notably on energy consumption. Lockdowns have fuelled the intensification of low-carbon resources in terms of electricity production, yet a drastic upswing in electricity use in residential districts during the pandemic. By exploring economic renewable energy resources, the world is trying to overcome the crisis and one of them is wind energy, where this sustainable energy system is highly demanded, thus reducing global CO2 emissions. Researchers have carried out several findings on wind energy obtained from wind turbines at various potential locations, but most of it used natural sources as a wind stream. Therefore, a revolutionary concept on extracting clean energy from manufactured wind resources with wind turbine system for power generation is introduced in recent studies. The main goal of this review paper is to emphasize the performances of power generation through Exhaust Air Energy Recovery Wind Turbine. The potentiality of wind extractions is reviewed to achieve the clear overview of this new progressive ideas and the important configurations is accentuated. Most findings indicated that this energy recovery device converts wasted energy to a more profitable form by converting it to electricity, resulting in a rapid return on investment. Moreover, the enclosing the output area of wind turbines for recovering energy enhances overall efficiency. © 2021. All Rights Reserved.

ABSTRACT

Introduction: The threshold for surgery has increased during the COVID-19 pandemic. A widely cited Chinese study (n=34) reported postoperative COVID-19 pneumonia and mortality rates of 100% and 21% respectively [1]. This audit assessed outcomes after abdominal surgery across three hospitals within Mid & South Essex NHS Foundation Trust. Methods: Patients undergoing abdominal surgery at Basildon University Hospital, Mid Essex Hospital and Southend University Hospital between 1st March and 27th April 2020 were included. Obstetric, gynaecological, vascular, inguinal/femoral hernia, and skin operations were excluded. Electronic data collection was supplemented by telephone follow-up. Results: 306 patients were included. The median age was 57 years. 148 (48.4%) were female. 156 (51.0%) and 150 (49.0%) patients underwent elective and emergency surgery respectively. The preoperative and postoperative SARS-CoV-2 rates (based on RT-PCR or imaging) were 0.3% (n=1) and 4.6% (n=14) respectively. 84.6% (n=259) did not have RT-PCR tests. All-cause 30-day mortality was 3.6% (n=11). Amongst patients with SARS-CoV-2, mortality was 50% (7/14), occurring only after emergency surgery. Elective (vs. emergency) surgery was associated with lower postoperative SARS-CoV-2 (0.6% vs. 8.7%;p<0.001) and mortality (0.6% vs. 6.7%;p=0.005). At follow-up, 79.1% (242/306) of patients responded, most (85.1%;206/242) without major clinical issue. Conclusion: Local SARS-CoV-2 and mortality rates are lower than previously reported [1]. Perioperative COVID-19 carries a high mortality risk. We recommend perioperative SARS-CoV-2 testing for all patients and cohorting by infection status.

ABSTRACT

Background: A novel coronavirus Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) discovered in China in December 2019 that has led to an unprecedented global pandemic. It causes coronavirus disease 19 (COVID-19), a respiratory illness with symptoms ranging from mild to severe with possible progression to pneumonia, multiple organ failure and even to death. Objectives: • To investigate the risk factors associated with COVID - 9 infections. • To investigate the occurrence and percentage of olfactory dysfunction in patients with COVID-19 infection. • To investigate the relationship between ABO and Rh blood groups and covid-19 infection. Methods: Blood samples were collected from 400 persons presenting with symptoms suggestive of COVID-19. These persons were admitted to Al Rabee hospital during a period from 1st June to 1st December 2020.ABO and Rh (D) blood groups test and covid-19 test were performed to all patients and control. COVID-19 test was confirmed by VIDAS methods. This study included 200 COVID-19 positive patients and 200 COVID-19 negative persons used as control. Results: Patients age ranged from 1 year to 80 years (mean age 54 years);the highest frequency of COVID-19 occurred in the age group (61-70) years. There were 120 (60%) males and 80 (40%) females with a ratio of 1.5:1. The most diffused risk factors associated with COVID-19 infection were older age, male sex and major comorbidities including (hypertension, cardiovascular disease, diabetes mellitus, chronic respiratory disease, obesity, smoking, chronic kidney disease, cancer, liver disease and malnutrition) 77% of patients reported olfactory dysfunction. The ABO blood group in 200 normal persons showed a distribution of 31%, 16%, 8% and 45% for A, B, AB and O, respectively vs. the ABO blood group in 200 COVID-19 positive patients showed a distribution of 46%, 18%, 9% and 27% for A, B, AB and O, respectively. ABO blood group was found to be significantly associated with COVID-19 status (P=0.001). The proportion of blood group A and O in COVID-19 patients were significantly higher and lower respectively than that in normal people (both P=0.001).No significant association was found between Rhesus negative (Rh-) blood group and occurrence of COVID-19 in present study. Conclusion: Our data found that the risk factors associated with COVID-19 infection were older age, male sex and comorbidities. And the risk of COVID-19 is higher with blood group A persons and lower with blood group O. Rhesus negative (Rh-) blood group associated with lower risk of COVID-19 illness.

ABSTRACT

Objective: To determine the effectiveness of therapeutic plasma exchange (TPE) in management of critically ill Covid-19 patients Materials and Methods: In this study non-randomized controlled trial, a total of 47 patients were included after thorough screening of the admitted patients in Covid ITC CMH, Multan from July-2020 to May-2021.Single administration of TPE was done to determine the results. The parameters assessed in this study included the efficacy of TPE in terms of improvement of critical end points such as Norepinephrine dose to maintain MAP of more than 65mmHg, 6-hour balance of fluid, MAP, CRP (C reactive protein), WBC count (white blood cell), platelets, INR (international normalized ratio), IL-6. Results: The variations before and after TPE in clinical and biochemical parameters shown in table. II. In clinical parameters and in gas exchange parameters no significant difference was found. Inflammatory biomarkers, before and after TPE, the parameters had not significant different, (p>0.005). The differences before and after TPE between acid base balance, cytokines and vasoactive substances were also statistically insignificant, (p>0.005). Conclusion: Even though there is evidence of slight improvement in clinical endpoints of Covid-19 patients with TPE, overall efficacy of TPE is still a question that needs an answer as no significant improvement could be seen in outcome values after TPE.

ABSTRACT

We describe the fourth edition of the CheckThat! Lab, part of the 2021 Conference and Labs of the Evaluation Forum (CLEF). The lab evaluates technology supporting tasks related to factuality, and covers Arabic, Bulgarian, English, Spanish, and Turkish. Task 1 asks to predict which posts in a Twitter stream are worth fact-checking, focusing on COVID-19 and politics (in all five languages). Task 2 asks to determine whether a claim in a tweet can be verified using a set of previously fact-checked claims (in Arabic and English). Task 3 asks to predict the veracity of a news article and its topical domain (in English). The evaluation is based on mean average precision or precision at rank k for the ranking tasks, and macro-F1 for the classification tasks. This was the most popular CLEF-2021 lab in terms of team registrations: 132 teams. Nearly one-third of them participated: 15, 5, and 25 teams submitted official runs for tasks 1, 2, and 3, respectively. © 2021, Springer Nature Switzerland AG.
