The post-traumatic stress disorder impact of the COVID-19 pandemic

On March 11, the World Health Organization (WHO) announced that the novel coronavirus disease 2019 (COVID-19) outbreak had become a global pandemic. The symptoms of COVID-19 are well known, and a range of treatments have been used to save lives. However, those who have recovered from COVID-19 may be struggling to mentally cope with what they have experienced physically. They may even develop signs and symptoms of an acute stress response, or post-traumatic stress disorder (PTSD). A question we face in the coming months is how to help survivors of severe COVID-19 recover. Although patients with confirmed or suspected cases of COVID-19, health care workers, and other people are showing signs of psychological problems related to the disease, survivors of previous diseases, health care workers, and front-line employees face a higher risk of infection and are more likely to be depressed, anxious, or even diagnosed with PTSD. Exposure, fear, isolation, loss of income, reduced autonomy, and the inability of health care professionals to cure coronavirus infections contribute to this increased stress. As everyone is vulnerable to COVID-19, providing mental health support will help people maintain their mental health and return to a heathy life more quickly. The objective of this paper is to explore the research progress of post-traumatic stress disorder (PTSD) related to COVID-19. (PsycInfo Database Record (c) 2021 APA, all rights reserved)

Coronavirus Disease 2019 (COVID-19) Mechanical Ventilation Research Theme Analysis: Co-word Cluster Analysis.

The objective of this analysis was to explore the research hotspot of coronavirus disease 2019 (COVID-19) mechanical ventilation. The literature related to COVID-19 mechanical ventilation on PubMed and CNKI database of core journals was retrieved with the keyword of COVID-19 mechanical ventilation. The visualisation software of VOS (visualisation of similarities) viewer performed by the authors and high-frequency keywords. A total of 524 English language articles from PubMed and 81 Chinese literature from China National Knowledge Infrastructure (CNKI) of core journals are included in this paper. The two databases produced six research fields, among which much attention was paid to the prevention of nosocomial infection and antiviral agents in the treatment of mechanical ventilation. The literature yeilded by PubMed paid attention to the factors affecting the poor prognosis of mechanically ventilated patients, the management and research and development of medical data during COVID-19's pandemic, the mechanical ventilation treatment of COVID-19 pregnant women, the mechanical ventilation treatment and nursing in the field of CNKI literature research, and the nutritional treatment of severe pneumonia patients with mechanical ventilation. The current COVID-19 researches, focused on the prevention of nosocomial infection and antiviral drugs in the process of mechanical ventilation, are a new hotspot in the world. Key Words: Coronavirus disease 2019 (COVID-19), Mechanical ventilation, Research hotspot, VOSviewer, Visual analysis.

[Analysis of research hotspot and frontier of severe coronavirus disease 2019: visual analysis based on CiteSpace].

OBJECTIVE: To analyze the research hotspot and frontier of severe coronavirus disease 2019 (COVID-19) in China and abroad. METHODS: The CiteSpace software was used to visually analyze the relevant research of severe COVID-19 published by CNKI and Web of Science databases from January 30th to April 20th in 2020. The analysis content included the author of the literature, the publishing institutions, and high-frequency keywords. RESULTS: There were 389 Chinese literatures and 59 English literatures included. Analysis using CiteSpace software showed that there were four large teams in China currently concerning about the research on severe COVID-19. The co-authoring of each team was relatively close, but the teams were lack of cooperation. The main issuing institutions were affiliated hospitals of colleges and universities, but colleges and enterprises had less participation. The authors of English-language publications mainly had five research teams, some of whom had co-authored relationships. The country with the most enormous volume of English-language publications was China, followed by the United States and Canada. The Chinese keyword co-occurrence, clustering and highlighted words analysis showed that the main research areas of severe COVID-19 included clinical features, traditional Chinese medicine treatment, medical imaging, integrated traditional Chinese and Western medicine treatment and so on; nucleic acid detection, clinical features and diagnosis, plague theory and etiology mechanism, traditional Chinese medicine and integrated Chinese and Western medicine treatment, severe COVID-19 combined with diabetes and prognosis research will become future research trends; keyword cluster analysis showed that severe COVID-19, combined chronic underlying diseases, CT imaging characteristics will also become new trends in the field of research. Co-occurrence analysis of keywords in English literatures showed that the main research areas of severe COVID-19 included the names of novel coronavirus, pandemic diseases, infectious diseases, medical supplies distribution, and indicators related to myocardial damage. CONCLUSIONS: Researchers in China and abroad have different concerns about severe COVID-19. Domestic research focuses on the diagnosis and treatment of severe cases, while foreign countries attach importance to epidemic response and prevention.

Epidemiology and Clinical Characteristics of COVID-19.

Since December 2019, there has been an outbreak of a novel coronavirus (COVID-19) infection in Wuhan, China. Meanwhile, the outbreak also drew attention and concern from the World Health Organization (WHO). COVID-19 is another human infectious disease caused by coronavirus. The transmission of COVID-19 is potent and the infection rate is fast. Since there is no specific drug for COVID-19, the treatment is mainly symptomatic supportive therapy. In addition, it should be pointed out that patients with severe illness need more aggressive treatment and meticulous care. Recently, accurate RNA detection has been decisive for the diagnosis of COVID-19. The development of highly sensitive RT-PCR has facilitated epidemiological studies that provide insight into the prevalence, seasonality, clinical manifestations and course of COVID-19 infection. In this review, we summarize the epidemiology and characteristics of COVID-19.
