ABSTRACT

In this study, we aimed to explore whether Lymphocyte-C-reactive protein ratio (LCR) can differentiate disease severity of Coronavirus disease 2019 (COVID-19) patients and its value as an assistant screening tool for admission to the hospital and the intensive care unit (ICU). A total of 184 adult COVID-19 patients from the COVID-19 Treatment Center in Heilongjiang Province at the First Affiliated Hospital of Harbin Medical University between January 2020 and March 2021 were included in this study. Patients were divided into asymptomatic infection group, mild group, moderate group, severe group, and critical group according to the Diagnosis and Treatment of New Coronavirus Pneumonia (9th edition). Demographic and clinical data including gender, age, comorbidities, severity of COVID-19, white blood cell count (WBC), neutrophil proportion (NEUT%), lymphocyte count (LYMPH), lymphocyte percentage (LYM%), red blood cell distribution width (RDW), platelet (PLT), C-reaction protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum creatinine (SCr), albumin (ALB), total bilirubin (TB), direct bilirubin (DBIL), indirect bilirubin (IBIL), and D-Dimer were obtained and collated from medical records at admission, from which sequential organ failure assessment (SOFA) score and LCR were calculated, and all above indicators were compared among groups. Multiple clinical parameters, including LYMPH, CRP and LCR, showed significant differences among groups. The related factors to classify COVID-19 patients into moderate, severe and critical groups included age, number of comorbidities, WBC, LCR, and AST. Among these factors, number of comorbidities showed the greatest effect, and only WBC and LCR were protective factors. The area under the receiver operating characteristic (ROC) curve of LCR to classify COVID-19 patients into moderate, severe and critical groups was 0.176. The cut-off value of LCR, and the sensitivity and specificity of ROC curve were 1780.7050, 84.6% and 66.2%, respectively. The related factors to classify COVID-19 patients into severe and critical groups included number of comorbidities, PLT, LCR, and SOFA score. Among these factors, SOFA score showed the greatest effect, and LCR was the only protective factor. The area under ROC curve of LCR to classify COVID-19 patients into severe and critical groups was 0.106. The cut-off value of LCR and the sensitivity and specificity of ROC curve were 571.2200, 81.3% and 90.0%, respectively. In summary, LCR can differentiate disease severity of COVID-19 patients and serve as a simple and objective assistant screening tool for hospital and ICU admission.

ABSTRACT

BACKGROUND: As a highly contagious disease, coronavirus disease 2019 (COVID-19) is wreaking havoc around the world due to continuous spread among close contacts mainly via droplets, aerosols, contaminated hands or surfaces. Therefore, centralized isolation of close contacts and suspected patients is an important measure to prevent the transmission of COVID-19. At present, the quarantine duration in most countries is 14 d due to the fact that the incubation period of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is usually identified as 1-14 d with median estimate of 4-7.5 d. Since COVID-19 patients in the incubation period are also contagious, cases with an incubation period of more than 14 d need to be evaluated. CASE SUMMARY: A 70-year-old male patient was admitted to the Department of Respiratory Medicine of The First Affiliated Hospital of Harbin Medical University on April 5 due to a cough with sputum and shortness of breath. On April 10, the patient was transferred to the Fever Clinic for further treatment due to close contact to one confirmed COVID-19 patient in the same room. During the period from April 10 to May 6, nucleic acid and antibodies to SARS-CoV-2 were tested 7 and 4 times, respectively, all of which were negative. On May 7, the patient developed fever with a maximum temperature of 39℃, and his respiratory difficulties had deteriorated. The results of nucleic acid and antibody detection of SARS-CoV-2 were positive. On May 8, the nucleic acid and antibody detection of SARS-CoV-2 by Heilongjiang Provincial Center for Disease Control were also positive, and the patient was diagnosed with COVID-19 and reported to the Chinese Center for Disease Control and Prevention. CONCLUSION: This case highlights the importance of the SARS-CoV-2 incubation period. Further epidemiological investigations and clinical observations are urgently needed to identify the optimal incubation period of SARS-CoV-2 and formulate rational and evidence-based quarantine policies for COVID-19 accordingly.

ABSTRACT

The coronavirus disease 2019 (COVID-19) epidemic is a major public health emergency characterized by fast spread, a wide range of infections, and enormous control difficulty. Since the end of December 2019, Wuhan has become the first core infection area of China's COVID-19 outbreak. Since March 2020, the domestic worst-hit areas have moved to the Heilongjiang Province due to the increased number of imported COVID-19 cases. Herein, we reported the major COVID-19 outbreak, which caused a rebound of the epidemic in Harbin, China. After the rebound, different levels of causes for the recurrence of COVID-19, including city-level, hospital-level, and medical staff-level cause, were investigated. Meanwhile, corresponding countermeasures to prevent the recurrence of the epidemic were also carried out on the city level, hospital level, and medical staff level, which eventually showed the effect of infection control function in a pandemic. In this study, we described the complete transmission chain, analyzed the causes of the outbreak, and proposed corresponding countermeasures from our practical clinical experience, which can be used as a valuable reference for COVID-19 control.

ABSTRACT

The large global outbreak of coronavirus disease 2019 (COVID-19) has seriously endangered the health care system in China and globally. The sudden surge of patients with severe acute respiratory syndrome coronavirus 2 infection has revealed the shortage of critical care medicine resources and intensivists. Currently, the management of non-critically ill patients with COVID-19 is performed mostly by non-intensive care unit (ICU) physicians, who lack the required professional knowledge, training, and practice in critical care medicine, especially in terms of continuous monitoring of the respiratory function, intervention, and feedback on treatment effects. This clinical problem needs an urgent solution. Therefore, here, we propose a series of clinical strategies for non-ICU physicians aimed at the standardization of the management of non-critically ill patients with COVID-19 from the perspective of critical care medicine. Isolation management is performed to facilitate the implementation of hierarchical monitoring and intervention to ensure the reasonable distribution of scarce critical care medical resources and intensivists, highlight the key patients, timely detection of disease progression, and early and appropriate intervention and organ function support, and thus improve the prognosis. Different management objectives are also set based on the high-risk factors and the severity of patients with COVID-19. The approaches suggested herein will facilitate the timely detection of disease progression, and thus ensure the provision of early and appropriate intervention and organ function support, which will eventually improve the prognosis.

ABSTRACT

The shortage of personal protective equipment and lack of proper nursing training have been endangering health care workers dealing with coronavirus disease 2019 (COVID-19). In our treatment center, the implementation of a holistic care model of time-sharing management for severe and critical COVID-19 patients has further aggravated the shortage of intensive care unit (ICU) professional nurses. Therefore, we developed a short-term specialized and targeted nursing training program to help ICU nurses to cope with stress and become more efficient, thus reducing the number of nurses required in the ICU. In order to avoid possible human-to-human spread, small teaching classes and remote training were applied. The procedural training mode included four steps: preparation, plan, implementation, and evaluation. An evaluation was conducted throughout the process of nursing training. In this study, we documented and shared experiences in transitioning from traditional face-to-face programs to remote combined with proceduralization nursing training mode from our daily work experiences during the COVID-19 pandemic, which has shown to be helpful for nurses working in the ICU.

ABSTRACT

To investigate the right heart function in coronavirus disease 2019 (COVID-19) patients with acute respiratory distress syndrome (ARDS), a retrospective analysis of 49 COVID-19 patients with ARDS was performed. Patients were divided into severe group and critically-severe group according to the severity of illness. Age-matched healthy volunteers were recruited as a control group. The cardiac cavity diameters, tricuspid annular plane systolic excursion (TAPSE), tricuspid valve regurgitation pressure gradient biggest (TRPG), pulmonary arterial systolic pressure (PASP), maximum inferior vena cava diameter (IVCmax) and minimum diameter (IVCmin), and inferior vena cava collapse index (ICV-CI) were measured using echocardiography. We found that the TAPSE was significantly decreased in pneumonia patients compared to healthy subjects (P < 0.0001), and it was significantly lower in critically-severe patients (P = 0.0068). The TAPSE was less than 17 mm in three (8.6%) severe and five (35.7%) critically-severe patients. In addition, the TAPSE was significantly decreased in severe ARDS patients than in mild ARDS patients. The IVCmax and IVCmin were significantly increased in critically-severe patients compared to healthy subjects and severe patients (P < 0.01), whereas the ICV-CI was significantly decreased (P < 0.05). COVID-19 patients had significantly larger right atrium and ventricle than healthy controls (P < 0.01). The left ventricular ejection fraction (LVEF) in critically-severe patients was significantly lower than that in severe patients and healthy controls (P < 0.05). Right ventricular function was impaired in critically-severe COVID-19 patients. The assessment and protection of the right heart function in COVID-19 patients should be strengthened.

ABSTRACT

The rapid global outbreak of coronavirus disease 2019 (COVID-19) and the surge of infected patients have led to the verge of exhaustion of critical care medicine resources worldwide, especially with regard to critical care staff. A holistic care model on time-sharing management for severe and critical COVID-19 patients is proposed, which includes formulation of individualized care objectives and plans, identification of care tasks in each shift and making detailed checklist, and management of quality of care. This study was conducted in the COVID-19 treatment center of Harbin, Heilongjiang Province. The data collected from the treatment center were recorded and analyzed. From the results we can deduce that it is especially suitable for non-intensive care unit (non-ICU) nurses to adapt care management mode of ICU as soon as possible and ensure the quality and efficiency of care during the epidemic. The holistic care model on time-sharing management for severe and critical cases with COVID-19 proposed based on our daily work experiences can assist in improving the quality and efficiency of care, thus reducing the mortality rate of patients in ICU.

ABSTRACT

Coronavirus disease (COVID-19) was first diagnosed in Wuhan in December 2019. The World Health Organization defined the subsequent outbreak of COVID-19 worldwide as a public health emergency of international concern. Epidemiological data indicate that at least 20% of COVID-19 patients have severe disease. In addition to impairment of the respiratory system, acute kidney injury (AKI) is a major complication. Immune damage mediated by cytokine storms and concomitant AKI is a key factor for poor prognosis. Based on previous experience of blood purification for patients with severe acute respiratory syndrome and Middle East respiratory syndrome combined with clinical front-line practice, we developed a blood purification protocol for patients with severe COVID-19. This protocol is divided into four major steps. The first step is to assess whether patients with severe COVID-19 require blood purification. The second step is to prescribe a blood purification treatment for patients with COVID-19. The third step is to monitor and adjust parameters of blood purification. The fourth step is to evaluate the timing of discontinuation of blood purification. It is expected that blood purification will play a key role in effectively reducing the mortality of patients with severe COVID-19 through the standardized implementation of the present protocol.
