Coronavirus disease 2019 (COVID-19): diagnosis and prognosis

Coronavirus disease 2019 (COVID-19) has become a global pandemic with a high rate of transmission. Currently, there is a lack of vaccines and specific drugs for this newly-emerged virus. Timely diagnosis and treatment, as well as isolation of patients and virus carriers, contribute to the effective prevention and control of this epidemic. This review focuses on early stage COVID-19 diagnosis methods and strategies, highlighting the guiding role of laboratory indicators on treatment strategy formulation, and prognosis assessments.     

新型冠状病毒病(COVID-19)研究进展

2019年12月,湖北省武汉市暴发了一种由新型冠状病毒引起的肺炎(COVID-19)随后蔓延到中国所有省区,WHO宣布其为全球关注的突发公共卫生事件。及时了解和表征该病毒对抗击疫情至关重要。通过收集和梳理该疫情暴发之后2个月内全球多领域研究人员关于COVID-19的论文,发现这些研究主要集中在溯源分析、检测手段、病患治疗、临床表现、药物研发、致病机理、传播途径、流行特征等方面。该冠状病毒与蝙蝠冠状病毒以及穿山甲冠状病毒相关,其利用与SARS-CoV相同的人受体ACE2,感染途径证实为呼吸系统和消化系统。该病毒具有人际传播能力,并且出现无症状传播。COVID-19确诊病例多数与武汉有关,大多数为轻症,年老者病死率较高。快速灵敏核酸检测通常作为确诊依据,目前已经筛选出有价值的候选药物如瑞德西韦进行临床试验。中国采取的旅行禁令和隔离等干预措施有效减轻了疫情蔓延。

2019年12月在湖北武汉出现不明原因肺炎,随后在国内和全球引起传播.目前,全球已有200多个国家出现感染病例,WHO将新型冠状病毒(简称为"新冠")引起的疫情暴发定义为全球大流行,严重危害人类的生命健康.我国经过前期的精准施策、科学防治,我国疫情已得到良好控制,取得了阶段性的胜利.在新冠肺炎患者的治疗中,通过对治疗方法的探索和实践,全国90％以上患者达到出院标准,在新冠肺炎的治疗中积累了宝贵的经验.本文就新冠肺炎的治疗作一综述,以期为新冠肺炎救治提供参考.     

Recommendations on how to provide cardiac rehabilitation services during the COVID-19 pandemic

The ongoing coronavirus disease 2019 (COVID-19) crisis is having a large impact on acute and chronic cardiac care. Due to public health measures and t     

Cardiac function in relation to myocardial injury in hospitalised patients with COVID-19

Neuroinflammation and COVID-19

Coronavirus disease 2019 (COVID-19) has caused a historic pandemic of respiratory disease. COVID-19 also causes acute and post-acute neurological symptoms, which range from mild, such as headaches, to severe, including hemorrhages. Current evidence suggests that there is no widespread infection of the central nervous system (CNS) by SARS-CoV-2, thus what is causing COVID-19 neurological disease? Here, we review potential immunological mechanisms driving neurological disease in COVID-19 patients. We begin by discussing the implications of imbalanced peripheral immunity on CNS function. Next, we examine the evidence for dysregulation of the blood-brain barrier during SARS-CoV-2 infection. Last, we discuss the role myeloid cells may play in promoting COVID-19 neurological disease. Combined, we highlight the role of innate immunity in COVID-19 neuroinflammation and suggest areas for future research.     

Epigenetic regulation of autophagy in coronavirus disease 2019 (COVID-19)

The coronavirus disease 2019 (COVID-19) pandemic has become the most serious global public health issue in the past two years, requiring effective therapeutic strategies. This viral infection is a contagious disease caused by new coronaviruses (nCoVs), also called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Autophagy, as a highly conserved catabolic recycling process, plays a significant role in the growth and replication of coronaviruses (CoVs). Therefore, there is great interest in understanding the mechanisms that underlie autophagy modulation. The modulation of autophagy is a very complex and multifactorial process, which includes different epigenetic alterations, such as histone modifications and DNA methylation. These mechanisms are also known to be involved in SARS-CoV-2 replication. Thus, molecular understanding of the epigenetic pathways linked with autophagy and COVID-19, could provide novel therapeutic targets for COVID-19 eradication. In this context, the current review highlights the role of epigenetic regulation of autophagy in controlling COVID-19, focusing on the potential therapeutic implications.

Cardiac complications in a geriatric population hospitalized with COVID-19: The OCTA-COVID cohort

PurposeThe geriatric population is especially vulnerable to coronavirus disease (COVID-19) and its potential complications. We sought to analyze the incidence of cardiological complications in an elderly population hospitalized for COVID-19.MethodsA prospective observational longitudinal that included patients ≥75 years of age with diagnosis of COVID-19 admitted to the Geriatric Department from March to May 2020. Epidemiological, geriatric, clinical and laboratory test variables were collected. Cardiovascular events, including de novo atrial fibrillation (AF), acute coronary syndrome (ACS), congestive heart failure (CHF), pulmonary embolism and in-hospital death, were documented. A follow-up was carried out at 12 months through a telephone interview as well as using electronic medical records, collecting cardiac events and mortality.Results305 patients were included; 190 (62.3%) were female, with median age of 87 years (interquartile range (82–91)). More than half of the patients had a history of cardiac disease, with AF being the most common and affecting 85 (27.9%) patients. During hospitalization, 112 (36.7%) patients died. Eighty-nine (29.2%) patients presented cardiac complications. Acute heart failure was the most prevalent (46; 15.1%), followed by new-onset AF (20; 6.5%), pulmonary embolism (17; 5.6%), and ACS (5; 1.6%). Patients with cardiac complications had a longer hospital stay (p < 0.001). During follow-up, 29 (15.1%) died, and 40 (20.8%) patients had a cardiovascular event being CHF the most prevalent complication (16.7%).ConclusionThe incidence of cardiovascular complications in geriatric patients is high and is associated with a longer hospital stay. CHF was the most frequent event, followed by AF.     

Cardiac rehabilitation and the changing cardiac rehabilitation directions in Hoensbroeck rehabilitation centre

Hoensbroeck Rehabilitation Centre has been providing inpatient and outpatient cardiac rehabilitation services since 1980. In these twenty years the patient population has changed considerably. Rehabilitation is currently focussing on the complex and often old patient. The programme that has been developed during this period consists of standard activities that are mainly group oriented. However, certain activities are provided on an individual basis. Based upon this variety of activities, a tailor-made programme can be composed for every individual patient. If the Hoensbroeck programme is compared with the directions given by the Dutch Society of Cardiology and the Netherlands Heart Foundation, the main difference is the use of an integrated approach instead of separate modules. In our view, this is a must for complex cardiac rehabilitation.     

Of mitochondrion and COVID-19

COVID-19, a pandemic disease caused by a viral infection, is associated with a high mortality rate. Most of the signs and symptoms, e.g. cytokine storm, electrolytes imbalances, thromboembolism, etc., are related to mitochondrial dysfunction. Therefore, targeting mitochondrion will represent a more rational treatment of COVID-19. The current work outlines how COVID-19’s signs and symptoms are related to the mitochondrion. Proper understanding of the underlying causes might enhance the opportunity to treat COVID-19.
