Abstract

Emergency trauma radiology, although a relatively new subspecialty of radiology, plays a critical role in both the diagnosis/triage of acutely ill patients, but even more important in providing leadership and taking the lead in the preparedness of imaging departments in dealing with novel highly infectious communicable diseases and mass casualties. This has become even more apparent in dealing with COVID-19, the disease caused by the novel coronavirus SARS-CoV-2, first emerged in late 2019. We review the symptoms, epidemiology, and testing for this disease. We discuss characteristic imaging findings of COVID-19 in relation to other modern coronavirus diseases including SARS and MERS. We discuss roles that community radiology clinics, outpatient radiology departments, and emergency radiology departments can play in the diagnosis of this disease. We review practical methods to reduce spread of infections within radiology departments.

Biological Treatment During COVID-19 Outbreak

Journal of Dermatological Treatment

Sriwijitalai, Won; Wiwanitkit, Viroj

Dear Editor,

We read the publication on ‘Should patients stop their biologic treatment during the COVID-19 pandemic’ and found that it is very interesting. Bashyam and Feldman raised an interesting issue for discussion regarding using biological treatment during COVID-19 outbreak. In fact, although there are infected patients worldwide, there has never any reports on biological treatment associated COVID-19. Whether, there is any problem relating to corticosteroid and TNF-α inhibitors in coronavirus infection is an interesting question. In a previous animal model study on coronavirus infection, TNF-α inhibitors did not deteriorate the disease course. Atanasova et al. found that blocking of TNF-α alone was not sufficient to ameliorate the disease. The immunopathology of the new disease is still largely unknown. It might be too early to conclude whether biological treatment should be ceased during COVID-19 outbreak.

COVID-19 Is A Disease Of Older People

The Journals of Gerontology: Series A

Le Couteur, David G.; Anderson, Rozalyn M.; Newman, Anne B.

Introduction

The case-fatality rate for COVID-19 increases dramatically with age from 3% to 5% between 65 and 74 years, 4% to 11% between 75 and 84 years, and 10% to 27% above 85 years and people aged 65 years and older account for 45% of hospitalizations, 53% of intensive care unit (ICU) admissions, and 80% of deaths (1). The first infections with the coronavirus, SARS-CoV-2, were recognized in December 2019 in Wuhan, China and since then, over 80,000 people in China contracted COVID-19, with more than 3,000 deaths (2). The United States has seen an exponential increase in the number of cases with the vast majority of deaths also occurring in people aged 65 years or older. Older people in residential aged care facilities and nursing homes have even greater risk of death given their age and comorbidities, confounded by the lack of capacity for social distancing from staff and other residents.

COVID-19 Outbreak And Inflammatory Bowel Disease Management: A Questionnaire Survey From Realistic Practice

Journal of Crohn's & Colitis

Bai, Xiaoyin; Yang, Hong; Qian, Jiaming

Introduction

Coronavirus disease 2019 [COVID-19] has swept Wuhan and other cities in China since January 2020.1 Despite the preliminary victory of containing the infection following 2 months of effort in China, the pandemic has posed a challenge regarding the routine clinical attention to patients with chronic disease. Inflammatory bowel disease [IBD] is a chronic disease which requires elaborate management. Due to the relative low incidence and prevalence of IBD,2 the limited number of specialists, and the individualised therapeutic approaches in our country, treatment recommendations still depend on the collaborative effort of experts in the high-volume hospitals. Nevertheless, given the severity of COVID-19, patients are adviseded to follow local primary physicians, which may result in unmet medical needs. In addition, most patients with IBD require glucocorticoids, immunomodulators, or biologic agents for a long time, which increases the likelihood of experiencing side effects and compromises the treatment outcome..

Abstract

Background

The novel coronavirus SARS-CoV-2 is a newly emerging virus. The antibody response in infected patient remains largely unknown, and the clinical values of antibody testing have not been fully demonstrated.

Methods

A total of 173 patients with SARS-CoV-2 infection were enrolled. Their serial plasma samples (n=535) collected during the hospitalization were tested for total antibodies (Ab), IgM and IgG against SARS-CoV-2. The dynamics of antibodies with the disease progress was analyzed.

Results

Among 173 patients, the seroconversion rate for Ab, IgM and IgG was 93.1%, 82.7% and 64.7%, respectively. The reason for the negative antibody findings in 12 patients might due to the lack of blood samples at the later stage of illness. The median seroconversion time for Ab, IgM and then IgG were day-11, day-12 and day-14, separately. The presence of antibodies was <40% among patients within 1-week since onset, and rapidly increased to 100.0% (Ab), 94.3% (IgM) and 79.8% (IgG) since day-15 after onset. In contrast, RNA detectability decreased from 66.7% (58/87) in samples collected before day-7 to 45.5% (25/55) during day 15-39. Combining RNA and antibody detections significantly improved the sensitivity of pathogenic diagnosis for COVID-19 (p<0.001), even in early phase of 1-week since onset (p=0.007). Moreover, a higher titer of Ab was independently associated with a worse clinical classification (p=0.006).

Conclusions

The antibody detection offers vital clinical information during the course of SARS-CoV-2 infection. The findings provide strong empirical support for the routine application of serological testing in the diagnosis and management of COVID-19 patients.

Foddai, Alessandro; Lubroth, Juan; Ellis-Iversen, Johanne

Abstract

The pandemic of new coronavirus disease COVID-19 is threatening our health, economy and life style. Collaborations across countries and sectors as a One Health World could be a milestone.

We propose a general protocol, for setting timely active random surveillance of COVID-19, at the human community level, with systematic repeated detection efforts. Strengths and limitations are discussed.

If considered applicable by public health, the protocol could evaluate the status of COVID-19 epidemics consistently and objectively.

Dear Editor,

On 30 January 2020, the World Health Organization (WHO) declared Coronavirus (CoV) disease 2019 (COVID-19) epidemic as a public health emergency. All age groups are susceptible to COVID-19. Pregnant women are at high risk of acquiring the infection possibly due to the immunologic changes of gestation. However, there is no evidence so far for severe outcomes for mothers. Premature delivery was reported in pregnant patients with COVID1-9 but it was unclear whether it was related to the infection.

Introduction

Since December 2019, the first case of a novel coronavirus (COVID-19) infection pneumonia was detected in Wuhan, and the outbreak has been spreading rapidly in the world. As of February 18, 2020, a total of 73,332 cases of confirmed COVID-19 infection have been detected in the world as reported by the WHO [1, 2]. Given that the asymptomatic persons are potential sources of COVID-19 infection [3], we report a familial cluster case of five patients infected with COVID-19 from an asymptomatic confirmed case in Beijing. We obtained the data of patients, which included demographic, epidemiological, and clinical features; chest radiography; laboratory test; and outcomes. Laboratory confirmation of COVID-19 was detected in the first hospital admission and verified by the Beijing Center for Disease Control and Prevention (CDC).

Abstract

The COVID-19 outbreak in China appears to reach the late stage since late March 2020, and a stepwise restoration of economic operations is implemented. Risk assessment for such economic restoration is of significance. Here, we estimated the probability of COVID-19 resurgence caused by work resuming in typical provinces/cities and found that such probability is very limited (&amp;lt;5% for all the regions except Beijing). Our work may inform provincial governments to make risk level-based, differentiated control measures.

COVID-19 Global Pandemic: Options for Management of Gynecologic Cancers

International journal of gynecological cancer: official journal of the International Gynecological Cancer Society

Ramirez, Pedro T.; Chiva, Luis; Eriksson, Ane Gerda Z.; Frumovitz, Michael; Fagotti, Anna; Gonzalez Martin, Antonio; Jhingran, Anuja; Pareja, Rene

Abstract

Our world is facing a devastating crisis in the growing pandemic associated with the coronavirus (COVID-19) disease. As many nations take steps to implement strategies to contain the spread of this disease, we continue to see the tremendous impact this is having on the numerous healthcare workers who unite to overcome this tragic infection. We also recognize the concerns by both physicians and patients as it pertains to the management of patients diagnosed with cancer. We recognize that in this special situation we must continue to provide our gynecologic oncology patients with the highest quality of medical services and at the same time assure that we maximize the safety not only of our patients and their families but also of the medical staff and all associated teams that care for patients both in the inpatient and outpatient settings. To that end, the Editorial Team of the International Journal of Gynecological Cancer have compiled evidence-based data using established guidelines to propose strategies to optimize care of our patients while at the same time offering potential options to alleviate the burden to the healthcare system when resources may need to be diverted to the direct care of patients affected by the coronavirus (COVID-19) disease. Our proposal is intended as a tool for consideration and certainly not as a strategy for permanent change in patterns of practice. The goal is to share options, as gathered collectively by our team, in both the management and surveillance of patients diagnosed with gynecologic cancers during this time of global crisis.

Weakened Defences

New Scientist
Volume 245, Issue 3275, 28 March 2020, Pages 20-21

Whyte, Chelsea

Introduction

The way society functions in the US has made it more vulnerable to pandemics. Could things be different, asks Chelsea Whyte.

The coronavirus outbreak is a once-in-a-century event – and it seems the US has spent the past 100 years unwittingly weakening its defences.

In fact, the US is probably the developed economy with the worst type of healthcare system to tackle COVID-19. Many economic and healthcare policies it has enacted don't prioritise public health, and it is finding out first-hand how dangerous that can be.

The impact of this has been seen in the past month or so in the lack of testing – as of 23 March, the US has done 238,632 tests compared with 338,036 in South Korea, a far smaller country.

To the Editor:

Recently, Repici et al1 proposed a model for prevention of COVID-19 infection spread in endoscopic units. The topic is of utmost importance because of the potential for fecal–oral transmission of the SARS-CoV-2,2 its prolonged persistence on different surfaces,3 and the fact that, from now on, an increasing number of procedures in patients known to be COVID-19 positive will be performed.

Quarantine Vehicle Scheduling for Transferring High-Risk Individuals in Epidemic Areas

International Journal of Environmental Research and Public Health 2020
Volume 17, Issue 7, March 2020, Page 2275

Zhang, Min-Xia; Yan, Hong-Fan; Wu, Jia-Yu; Zheng, Yu-Jun

Abstract

In a large-scale epidemic outbreak, there can be many high-risk individuals to be transferred for medical isolation in epidemic areas. Typically, the individuals are scattered across different locations, and available quarantine vehicles are limited. Therefore, it is challenging to efficiently schedule the vehicles to transfer the individuals to isolated regions to control the spread of the epidemic. In this paper, we formulate such a quarantine vehicle scheduling problem for high-risk individual transfer, which is more difficult than most well-known vehicle routing problems. To efficiently solve this problem, we propose a hybrid algorithm based on the water wave optimization (WWO) metaheuristic and neighborhood search. The metaheuristic uses a small population to rapidly explore the solution space, and the neighborhood search uses a gradual strategy to improve the solution accuracy. Computational results demonstrate that the proposed algorithm significantly outperforms several existing algorithms and obtains high-quality solutions on real-world problem instances for high-risk individual transfer in Hangzhou, China, during the peak period of the novel coronavirus pneumonia (COVID-19).

This year, the Chinese New Year celebration coincided with the emergence of a SARS-CoV-2 outbreak in the country. The infection soon spread around the world, so that on March 11, 2020, the World Health Organization declared the outbreak a pandemic. In response, many mainstream journals soon began publishing important and relevant articles so that within a short period, numerous articles were available to the very busy health care workers fighting the disease in the front line of the battle. The virus was completely unknown. Most of health professionals were too busy to review the increasing number of published articles, some of which consisted of science intertwined with superstitions…

Introduction

The absence of COVID-19 testing for NHS staff is causing huge workforce shortages by forcing doctors to self-isolate even if they do not have the virus, the head of the BMA has warned.

The government’s advice is for people with COVID-19 symptoms to stay at home for seven days, but for all other household members who remain well to isolate for 14 days. The BMA council chairman, Chaand Nagpaul, said that the lack of testing for staff was “counter-intuitive” as it was likely to be forcing more staff than necessary to stay away from hospitals and GP surgeries because they do not know if they are infected.
