ABSTRACT

BACKGROUND: Particularly at the beginning, the COVID-19 (coronavirus disease 2019) pandemic caused a reduction in the number of interventions in interventional radiology. At the same time, interventional training became more challenging. Infectious patients and disease transmission within interventional radiology departments continue to pose significant challenges. OBJECTIVES: This article describes the status and recommendations for interventional radiological procedures in COVID-19 patients. MATERIALS AND METHODS: Guidelines and recommendations from international and national societies as well as original works and reviews were evaluated. RESULTS: Interventional radiological care of COVID-19 patients with complicated courses of infection has become established during the course of the pandemic. To protect patients and staff, interventions in COVID-19 patients should be prioritized, performed in separate procedure rooms if possible, and patients should be tested before interventions. Logistics, staff planning, and hygiene measures should be continuously optimized. CONCLUSIONS: Structured workflows within interventional radiology in dealing with COVID-19 patients appear necessary to minimize infection risks and to guarantee the staff's work capability and health. In order to develop concepts for the handling of COVID-19 patients and to be prepared for potential upcoming waves of infections, recommendations of the Robert Koch Institute (RKI) and (inter-)national professional societies are helpful.

ABSTRACT

Background: Severe Acute respiratory Syndrome Coronavirus 2 (SARS-Cov-2/COVID 19) infection was firstly described in Wuhan, China during December 2019. Covid 19 patient can present with numerous clinical presentations ranging from Asymptomatic to critical clinical courses. HRCT thorax findings proved to be crucial in assessing the clinical course of patients requiring treatment. Materials And Methods: It was a cross sectional study done in Dr D Y Patil Medical College. Patients >12 years of age who were RT PCR Positive for COVID 19 and met the inclusion criteria were selected for the study. After which they were categorized in to mild moderate category according to guidelines. HRCT was done for all patients and CT severity score was also assessed Results: We evaluated a sample population of 100 patients. The most predominant symptoms in the moderate category were shortness of breath. The most common radiological abnormality noted was Ground glass opacity (50%) with 43patients in mild and 7 patients in moderate category. Lung involvement in mild stage was only 20 to 40% when compared to that of moderate category where the lung involvement was 50 to 60% and this showed statistical significance Conclusion(s): CT scoring could help to identify patient's risk and predict outcome of patient with COVID 19 Pneumonia. The extent of lung involvement is highly correlated with parameters of disease such as clinical staging. Finally, our study strongly supports the use of chest CT in patient with the covid 19 pneumonia, which could be used as a tool for rapid and effective method to evaluate the lung involvement. It can also help in taking clinical decision. Copyright © 2023 Ubiquity Press. All rights reserved.

ABSTRACT

Common cold and influenza are often complicated by pneumococcal pneumonia, but the complication whereas pneumococcal pneumonia complicating COVID-19 is not common. Both influenza and COVID-19 are respiratory viral infections, and their pathogenesis depends on the host immune response. Therefore, clinically, accurate pathogen diagnosis in the early stage of the clinical course for the purpose of formulating an appropriate treatment plan may contribute to improvement of the patient prognosis. Clinical characteristics of COVID-19 in clinical manifestations, epidemiological history, laboratory findings and radiological findings, some of which were different and some of which were similar from influenza or any other common cold. We would like to emphasize the importance of researching the mechanism of pneumonia induced from common cold, influenza, COVID-19 and any other respiratory viral infection.

ABSTRACT

The world is restoring life balance after the global Covid-19 pandemic. This situation, giving birth to new problems, arose as an outcome of pre-and post pandemic scenarios. Healthcare system was under tremendous burden during this pandemic. Government bodies, scientists, drug discovery and drug registration were working in cooperation to fight the situation and to save lives. Out of all such activities, one healthcare domain is a key player, and that is the radiological department of hospitals. As discovery made those Covid-19 effects on lungs, the pressure on CT scan activities rose. To generate a CT scan quickly and to diagnose lung condition is the need of hour. Furthermore, that became a challenge for early detection of lung conditions. Hence, this paper presents the proposed research to develop iterative techniques using deep learning computation. Paper presents the proposed lung image acquisition and augmentation algorithm developed using a convolution neural network named "AquiCNN". This proposed algorithm will be useful for quick and enhanced lung CT image analysis. Copyright © 2022 Wolters Kluwer Medknow Publications. All rights reserved.

ABSTRACT

PURPOSE The COVID-19 pandemic forced healthcare officials to implement new policies, such as the use of virtual consultations over office-based medical appointments, to reduce the transmission of the virus. The purpose of this study is to quantitatively compare patients' experiences with virtual outpatient telemedicine encounters at a single academic institution in Interventional Radiology (IR) and in-person visits during the course of the COVID-19 pandemic. METHODS The TeleENT Satisfaction Questionnaire and the Medical Communication Competence Scale (MCCS) were used to survey patients' satisfaction with both in-person and virtual office visits. RESULTS Ninety respondents (38 in-person, 52 virtual) acknowledged numerous benefits of virtual visits versus in-person office visits including reductions in time, cost, and potential viral transmission risk during the COVID-19 pandemic. No statistically significant difference was noted, based on a Likert scale from 1 to 7, between in-person and virtual visits (all p > 0.05) for scheduling related factors. No statistically significant difference was noted in any of the MCCS subscales between the two cohorts in regards to medical information communication (all p > 0.05). A majority of patients with virtual encounters (82.7%) stated that it was easy to obtain an electronic device for use during the telemedicine visit, and 73.1% of patients felt that setting up the telemedicine encounter was easy. CONCLUSION This study demonstrates that telemedicine is an acceptable alternative to in-office appointments and could increase access to IR care outside of the traditional physician-patient interaction. With telemedicine visits, patients can communicate their concerns and obtain information from the doctor with noninferior communication compared to in-person visits.

ABSTRACT

The spread of severe acute respiratory syndrome coronavirus 2 worldwide has created a major threat to human life and safety. Antiviral drugs and antibiotics have poor therapeutic effects, and there is no specific treatment for this virus. Chest computed tomography (CT) plays an important role in the diagnosis and management of coronavirus disease 2019 (COVID-19). We report a patient who was critically ill with COVID-19 and recovered after receiving transfusions of convalescent plasma. To evaluate the efficacy of convalescent plasma in the treatment of COVID-19, we compared chest CT findings, clinical manifestations, and laboratory findings before and after treatment with convalescent plasma. After the transfusion of convalescent plasma, clinical manifestations and indicators of inflammation improved, accompanied by an increase in the partial pressure of oxygen and oxygen saturation. Chest CT showed some resolution of the lung lesions, and multiple viral nucleic acid tests were negative. Therefore, the patient's condition was improved after the transfusion of convalescent plasma, suggesting that it may be an effective treatment for patients who are critically ill with COVID-19.

ABSTRACT

OBJECTIVE: Research has shown that older people and smokers have a higher death probability from coronavirus disease 2019 (COVID-19). Thus, we investigated the effect of COVID-19 on death probability for individuals aged 65–70 years and smokers in India. MATERIALS AND METHODS: We did so using a differential learning (feed-backward) model. In the present study, we examined World Health Organization (WHO) declared COVID-19 data of India. We divided the patients into two groups accordingly: the population aged 65–70 years and female or male smokers. RESULTS: We observed that in the early stages of infection (up to 5 days), there was higher death probability in the older population;among smokers, it occurred in the middle period after infection (5–8 days). We estimated that the death probability among smokers was 1.905 times that of the older population. CONCLUSION: As Government of India, taking various initiatives to curb the spread of COVID-19, but these are not enough, so we suggest measures that should help to reduce COVID-19 infection in India.

ABSTRACT

Background: Radiology education in Turkey is mainly taught during clinical years of medical school and often lacks main principles. Exposure to the fundamentals of radiology at an early stage of medical education may drastically help students generate a better understanding of radiology and expand their interest in the specialty. With the Principles of Radiology Course that we provided, pre- and post-session tests, and assessment survey at the end of the course, we aimed to evaluate the effectiveness of such an online course among Turkish medical students. Methods: A total of nine online sessions on imaging modalities principles was developed by radiology professors. Each session was given through Zoom by radiologists from different U.S.-institutions to Turkish medical students from state (n = 33) and private (n = 8) universities. Pretests and post-tests were given to participants via Qualtrics before and after each session, respectively. Paired two-sample t-tests were conducted to detect the variance and p=-.05 was used as the significance level. An evaluation survey was distributed at the end of the course to collect their feedback through SurveyMonkey. Results: A total of 1,438 predominantly Turkish (99.32%) medical students engaged with this course. An average of 506 students completed both pre-test and post-test. There was a statistically significant (p < .001) increase in the scores in post-test (mean[range]:7.58[5.21-8.53]) relative to pre-test (mean[range]:5.10[3.52-8.53]). Four hundred and thirty-nine participants (F/M:63.33%/35.54%) completed the end-of-course survey. A total of 71% and 69.70% of the participants strongly agreed that the course would be useful in their clinical practice and had increased their understanding of radiology. They also reported that their level of confidence in the subjects had increased 68% and reached a weighted average of 3.09/4. The survey revealed that 396 (90.21%) of the participants strongly or somewhat agree that introductory principles and concepts should be presented in earlier years of medical education. Compared to in-person education, 358 (81.55%) found the course extremely or very convenient. Conclusion: Online lecture series consisting of the principles of the radiological imaging modalities can be offered to Turkish medical students to enhance their grasp of the various imaging modalities and their correct clinical application.

ABSTRACT

Arterio-ureteral fistulas (AUF) are extremely rare and are not commonly suspected in the setting of patients with post-renal allograft transplantation. The diagnosis, while uncommon, can be potentially lethal which is only exacerbated by the clinical conundrum associated with their under-recognition and various treatment algorithms. This case identifies a unique patient with a history of 2 failed renal transplants who presents with new onset intermittent hematuria after contracting coronavirus disease 2019 (COVID-19). Despite the patient having his second renal transplant graft embolized, the patient continued to present with refractory hematuria, leading to the realization and identification of an AUF to his right renal graft. This sequence of events brings forth a case of unique significance, underscoring the potential ramifications that COVID-19 poses to the renal transplant population.

ABSTRACT

Purpose: Recently, the SARS-CoV-2 Omicron variant was identified as responsible for a novel wave of COVID-19 worldwide. We perform a retrospective study to identify potential risk factors contributing to radiological progression in the COVID-19 patients due to the Omicron variant infection. These findings would provide guiding information for making clinical decisions that could improve the Omicron infection prognosis and reduce disease-related death. Methods: This is a retrospective cohort study from a single center in China. According to the radiological change within admissive one week, enrolled cases were divided into two groups: the progressive (1w-PD) and the stable or improved disease (1w-non-PD). Separate analyses were performed on patients stratified into subgroups using the Mann-Whitney U-test, the Fisher exact test, or the Chi-squared test and a multivariable logistic regression analysis. Results: Both the 1w-non-PD and 1w-PD cohorts displayed comparable asymptomatic infection, have similar underlying disease, impairment in respiratory function, coagulation dysfunction, tissue injury, SARS-CoV-2 viral load, and disease severity. However, the 1w-PD cohort was more inclined to cluster in populations presented with age between 41 and 65, higher CURB-65 scores, undetectable SARS-CoV-2 IgG, and lung affection. Based on the multiple logistic regression analysis, complicated bilateral and ground-glass opacities (GGOs) like pneumonia at admission were independent risk factors to radiological progression within admissive one week. Conclusion: This study provided preliminary data regarding disease progression in Omicron-infected patients that indicated the development of pneumonia in the context of Omicron infection was worthy of potential risk factors.

ABSTRACT

BACKGROUND AND AIM: We aimed to examine the demographic, clinical, and imaging characteristics of patients with COVID???19 pneumonia and also to identify the factors affecting mortality. MATERIALS AND METHODS: This study was designed as a retrospective single???center observational study. A total of 126patients with COVID???19 pneumonia who were polymerase chain reaction confirmed and underwent thorax computer tomography(CT) were analyzed. The patients' demographic and clinical data were obtained from the electronic medical record. Thorax CT findings were re???evaluated retrospectively by thoracic radiologists according to the severe acute respiratory syndrome coronavirus 2 pneumonia guidelines of the Radiological Society of North America. The extent of lesions was evaluated by CT lobe score, which was the sum of individual lobe scores(0-5 point) of the lungs. RESULTS: The mean age of the patients was 60.4 +/- 18.6years and 54%(n=68) were male. The most common symptoms included cough, fever, and shortness of breath. The average time interval between the onset of symptoms and thorax CT acquisition was 6.6 +/- 8.3days. The most common radiological findings included ground???glass opacity(98.4%), consolidation(72.2%), and vascular enlargement(69.8%), respectively. The deceased patients had more common consolidation, vascular enlargement, and high lobe scores in thorax CT as compared to survivors. According to logistic regression analysis age(P=0.003), lobe score(P=0.001), numbers of comorbidities(P=0.017), symptoms duration(P=0.034), and vascular enlargement(P=0.045) were independent risk factors on 30???day mortality. CONCLUSION: This study indicated that age, symptoms duration, the number of comorbidities, lobe score, and vascular enlargement in thorax CT are associated with the prognosis of COVID???19 pneumonia

ABSTRACT

Purpose There is a scarcity of literature examining changes in radiologist research productivity during the COVID-19 pandemic. The current study aimed to investigate changes in academic productivity as measured by publication volume prior to and during the COVID-19 pandemic. Methods This single-center retrospective cohort study, included the publication data of 216 researchers consisting of associate professors, assistant professors, and professors of radiology. Wilcoxin sign rank test was used to identify changes in publication volume between the a 1-year long defined pre-pandemic period (publications between May 1, 2019 to April 30, 2020) and COVID-19 pandemic period (May 1, 2020 to April 30, 2021). Results There was a significantly increased mean annual volume of publications in the pandemic period (5.98, SD = 7.28) compared to the pre-pandemic period (4.98, SD = 5.53) Z = -2.819, p = 0.005. Subset analysis demonstrated a similar (17.4%) increase in publication volume for male researchers when comparing the mean annual pre-pandemic publications (5.10, SD = 5.79) compared to the pandemic period. (5.99, SD = 7.60) Z = -2.369, p = .018. No statistically significant changes were found in similar analyses with the female subset. Discussion Significant increases in radiologist publication volume were found during the COVID-19 pandemic compared to the year prior. Changes may reflect an overall increase in academic productivity in response to clinical and imaging volume ramp down.

ABSTRACT

COVID-19 disease caused by the SARS-CoV-2 virus has created social and economic disruption across the world. The ability of the COVID-19 virus to quickly mutate and transfer has created serious concerns across the world. It is essential to detect COVID-19 infection caused by different variants to take preventive measures accordingly. The existing method of detection of infections caused by COVID-19 and its variants is costly and time-consuming. The impacts of the COVID-19 pandemic in developing countries are very drastic due to the unavailability of medical facilities and infrastructure to handle the pandemic. Pneumonia is the major symptom of COVID-19 infection. The radiology of the lungs in varies in the case of bacterial pneumonia as compared to COVID-19-caused pneumonia. The pattern of pneumonia in lungs in radiology images can also be used to identify the cause associated with pneumonia. In this paper, we propose the methodology of identifying the cause (either due to COVID-19 or other types of infections) of pneumonia from radiology images. Furthermore, because different variants of COVID-19 lead to different patterns of pneumonia, the proposed methodology identifies pneumonia, the COVID-19 caused pneumonia, and Omicron caused pneumonia from the radiology images. To fulfill the above-mentioned tasks, we have used three Convolution Neural Networks (CNNs) at each stage of the proposed methodology. The results unveil that the proposed step-by-step solution enhances the accuracy of pneumonia detection along with finding its cause, despite having a limited dataset. © 2023 Tech Science Press.

ABSTRACT

Introduction: Recognition of death risk factors is urgently needed, not only to identify the defining clinical and epidemiological characteristics with greater precision but also to facilitate the appropriate supportive care and prompt access to the intensive care unit (ICU) if necessary. This study aimed to investigate the influencing demographic characteristics, comorbidities disease, and radiologic finding on COVID-19 death. Method: Descriptive cross-sectional study included adult patients with COVID-19 from Imam Hossein. Demographic characteristics, comorbidities disease, chest CT scan findings, and outcome (death/survive) data were extracted from information health system (HIS), by using a data collection check list. To explore the influencing factors on mortality, logistic regression method was used. Result: Result demonstrated that most patients who died because of Covid-19 were men (63.4%), more than 60 years (86.4%), married (95.8%), and self-employed (37.1%) with a mean age of 72.1 +or- 15.46 years ranging from 22 to 93 years. Having comorbidities disease such as cancer, cardiac disease, diabetes, age, and pathologic chest CT findings was associated with death. In contrast, gender, marital, job, cerebral vascular disease, and HTN were not correlated.

ABSTRACT

Introduction:This study aims to look at the trends in our head and neck cancer patient population over the past 5 years with an emphasis on the past 2 years to evaluate how the coronavirus disease 2019 (COVID-19) pandemic has impacted our disparities and availability of care for patients, especially those living in rural areas. An additional aim is to identify existing disparities at our institution in the treatment of head and neck patients and determine solutions to improve patient care.Materials and Methods:A retrospective chart review was performed to identify patients who were consulted and subsequently treated with at least one fraction of radiation therapy at our institution with palliative or curative intent. Patient demographic information was collected including hometown, distance from the cancer centre based on zip-codes and insurance information and type of appointment (in-person or telehealth). Rural–urban continuum codes were used to determine rurality.Results:A total of 490 head and neck cancer patients (n = 490) were treated from 2017 to 2021. When broken down by year, there were no significant trends in patient population regarding travel distance or rurality. Roughly 20–30% of our patients live in rural areas and about 30% have a commute > 50 miles for radiation treatment. A majority of our patients rely on public insurance (68%) with a small percentage of those uninsured (4%). Telehealth visits were rare prior to 2019 and rose to 5 and 2 visits in 2020 and 2021, respectively.Conclusions:Head and neck cancer patients, despite rurality or distance from a cancer centre, may present with alarmingly enough symptoms despite limitations and difficulties with seeking medical attention even during the COVID-19 pandemic in 2020. However, providers must be aware of these potential disparities that exist in the rural population and seek to address these.
