Paxlovid administration in elderly patient with COVID-19 caused by Omicron BA.2.0: A case report.

Rationale: Paxlovid has shown the potential decreasing the hospitalization rate of mild or moderate coronavirus disease 2019 (COVID-19) and death in few of clinical trials, and is expected to the most promising medicine targeting Severe Acute Respiratory Syndrome Coronavirus 2 (SRAS-COV-2). However, there are no enough evidences to show it effectiveness for all patients with SARS-COV-2, especially among elderly patients and newest Omicron variant.

Patient Concerns And Diagnosis: A 79 year's old female patient was admitted to hospital because of the moderate COVID-19 caused by the Omicron variant BA2.

Paper Device Combining CRISPR/Cas12a and Reverse-Transcription Loop-Mediated Isothermal Amplification for SARS-CoV-2 Detection in Wastewater.

Wastewater-based surveillance of the COVID-19 pandemic holds great promise; however, a point-of-use detection method for SARS-CoV-2 in wastewater is lacking. Here, a portable paper device based on CRISPR/Cas12a and reverse-transcription loop-mediated isothermal amplification (RT-LAMP) with excellent sensitivity and specificity was developed for SARS-CoV-2 detection in wastewater. Three primer sets of RT-LAMP and guide RNAs (gRNAs) that could lead Cas12a to recognize target genes via base pairing were used to perform the high-fidelity RT-LAMP to detect the N, E, and S genes of SARS-CoV-2.

IgG antibody titers against SARS-CoV-2 nucleocapsid protein correlate with the severity of COVID-19 patients.

Background: The 2019 novel coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 virus (SARS-CoV-2) is a current worldwide threat for which the immunological features after infection need to be investigated. The aim of this study was to establish a highly sensitive and quantitative detection method for SARS-CoV-2 IgG antibody and to compare the antibody reaction difference in patients with different disease severity.

Results: Recombinant SARS-CoV-2 nucleocapsid protein was expressed in Escherichia coli and purified to establish an indirect IgG ELISA detection system.

Epidemiological characteristics and clinical manifestations of pediatric patients with COVID-19 in China: A multicenter retrospective study.

Importance: The Coronavirus disease 2019 (COVID-19) global pandemic poses a considerable challenge for pediatricians.

Objective: This study aimed to identify the epidemiological characteristics and clinical features of pediatric patients with COVID-19 in China.

Methods: This multicenter retrospective study included pediatric patients from 46 hospitals in China, covering 12 provinces and two municipalities.

Critical roles of cytokine storm and secondary bacterial infection in acute kidney injury development in COVID-19: A multi-center retrospective cohort study.

Acute kidney injury (AKI) may develop in patients with coronavirus disease 2019 (COVID-19) and is associated with in-hospital death. We investigated the incidence of AKI in 223 hospitalized COVID-19 patients and analyzed the influence factors of AKI. The incidence of cytokine storm syndrome and its correlation with other clinicopathologic variables were also investigated.

Comparison of Clinical Characteristics Among COVID-19 and Non-COVID-19 Pediatric Pneumonias: A Multicenter Cross-Sectional Study.

Background: The pandemic of Coronavirus Disease 2019 (COVID-19) brings new challenges for pediatricians, especially in the differentiation with non-COVID-19 pneumonia in the peak season of pneumonia. We aimed to compare the clinical characteristics of pediatric patients with COVID-19 and other respiratory pathogens infected pneumonias.

Methods: We conducted a multi-center, cross-sectional study of pediatric inpatients in China.

Angiotensin (1-7) Alleviates Postresuscitation Myocardial Dysfunction by Suppressing Oxidative Stress Through the Phosphoinositide 3-Kinase, Protein Kinase B, and Endothelial Nitric Oxide Synthase Signaling Pathway.

There is increasing evidence that angiotensin (1-7) [Ang (1-7)] is an endogenous biologically active component of the renin-angiotensin system. However, the role of the Ang (1-7)-MasR axis in postresuscitation myocardial dysfunction (PRMD) and its associated mechanism are still unclear. In this study, we investigated the effect of the Ang (1-7)-MasR axis on myocardial injury after cardiac arrest-cardiopulmonary resuscitation-restoration of spontaneous circulation.

An HIV-infected patient with coronavirus disease 2019 has a favourable prognosis: a case report.

The coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread rapidly, which now has turned into a pandemic. The new emerging infectious disease has raised many challenges and uncertainties regarding disease management and prognosis in immunocompromised patient populations. The risk of COVID-19 among people living with human immunodeficiency virus (HIV) has different opinions.

Knockdown of CCNO decreases the tumorigenicity of gastric cancer by inducing apoptosis.

Purpose: Recently, Cyclin O (CCNO) has been reported to be a novel protein of the cyclin family. However, the clinical significance and functional roles of CCNO in human cancer, including gastric cancer (GC), remain largely unexplored. In this study, we investigated the clinical and functional roles of CCNO in GC.

Erythropoietin alleviates post-resuscitation myocardial dysfunction in rats potentially through increasing the expression of angiotensin II receptor type 2 in myocardial tissues.

Activation of renin-angiotensin system (RAS) is one of the pathological mechanisms associated with myocardial ischemia-reperfusion injury following resuscitation. The present study aimed to determine whether erythropoietin (EPO) improves post‑resuscitation myocardial dysfunction and how it affects the renin‑angiotensin system. Sprague‑Dawley rats were randomly divided into sham, vehicle, epinephrine (EP), EPO and EP + EPO groups.

[Protective effect of erythropoietin on brain tissue in rats with cardiopulmonary resuscitation after asphyxia].

Objective: To study the protective effect of erythropoietin (EPO) on brain tissue with cardiac arrest-cardiopulmonary resuscitation (CA-CPR) and its mechanism.

Methods: 120 male Sprague-Dawley (SD) rats were randomly divided into three groups (each n = 40), namely: sham group, routine chest compression group, and conventional chest compression + EPO group (EPO group). The rats in each group were subdivided into CA and 6, 12, 24, 48 hours after restoration of spontaneous circulation (ROSC) five subgroups (each n = 8).

[Comparison of value of GRACE, APACHEII and REMS for early prognosis of death in patients with acute myocardial infarction].

Objective: To evaluate and compare the predictive value of short-term risk of death of global registry of acute coronary events (GRACE) risk scores, acute physiology and chronic health evaluation II (APACHEII) scores and rapid emergency medicine score (REMS) in patients with acute myocardial infarction (AMI).

Methods: A retrospective review of clinical data of 390 patients with AMI admitted from October 2012 to March 2013 in emergency department and cardiology care unit (CCU) in Guizhou People's Hospital were performed. The lowest scores within 24 hours of GRACE risk score, APACHEII risk score, and REMS risk score, respectively, for each patient were recorded.
