RESUMEN
BACKGROUND: The current global pandemic of COVID-19 is considered a public health emergency. The diagnosis of COVID-19 depends on detection of the viral nucleic acid by real time reverse transcription polymerase chain reaction (RT-PCR). However, false-negative RT-PCR tests are reported and could hinder the control of the pandemic. Chest computed tomography could achieve a more reliable diagnosis and represent a complementary diagnostic tool. AIM: To perform a meta-analysis and systematic review to find out the role of chest computed tomography versus RT-PCR for precise diagnosis of COVID-19 infection. METHODS: We searched three electronic databases (PubMed, ScienceDirect, and Scopus) from April 1 to April 20, 2020, to find out articles including the accuracy of chest computed tomography scan versus RT-PCR for diagnosis of SARS-CoV-2 infection. Observational studies, case series, and case reports were included. RESULTS: A total of 238 articles were retrieved from the search strategy. Following screening, 39 articles were chosen for full text assessment and finally 35 articles were included for qualitative and quantitative analysis. Chest computed tomography showed a wide range of sensitivity varied from 12%-100%. CONCLUSION: Chest computed tomography is playing a key role for diagnosis and detection of COVID-19 infection. Computed tomography image findings may precede the initially positive RT-PCR assay.
RESUMEN
Background: In many health systems, primary care is the main source of health care services. Liver cirrhosis is a silent disease that causes no signs or symptoms until decompensation occurs. Therefore, a simple and readily accessible tool for predicting advanced liver fibrosis and cirrhosis is needed to aid general practitioners in primary care settings. Aim: To explore the predictive performance of Albumin Bilirubin (ALBI) score as a non-invasive serum biomarker for advanced liver fibrosis and cirrhosis. Methods: This case-control study was conducted at Zagazig University Hospitals, Egypt, and comprised 400 participants divided into two equal groups. Group (I): 200 chronic HCV patients with advanced liver fibrosis and cirrhosis [F3-F4] and Group (II): 200 healthy controls. ALBI score was calculated for all study participants. Results: The AUROC for the ALBI score was 0.832 (95% CI: 0.787-0.872) (p-value) Conclusion: ALBI score is reliable for predicting advanced liver fibrosis and cirrhosis and could be valuable in primary care
