Article Abstract

Background: Coronavirus disease 2019 (COVID-19) has evolved into a pandemic. We hypothesized that biochemical indicators of liver function may help determine the prognosis of COVID-19 patients.

Methods: Patient information was collected from the Wuhan-Leishenshan hospital. Logistic and Cox regression analyses, Kaplan-Meier curves, and Curve fitting were used to determine the correlation between elevated levels of aspartate transaminase (AST), alanine transaminase (ALT), and AST/ALT and severity of disease/mortality.

Results: Logistic and Cox regression analyses and Kaplan-Meier survival curves showed that COVID-19 progression correlated with elevated levels of AST and AST/ALT. The odds ratios for elevated levels of AST and AST/ALT in patients were 0.818 (95% confidence interval [CI]: 0.274-2.441, P = 0.035) and 2.055 (95% CI: 1.269-3.327, P = 0.003), respectively; the hazard ratios were 4.195 (95% CI: 1.219-14.422, P = 0.023) and 3.348 (95% CI: 1.57-7.139, P = 0.002), respectively. The Kaplan-Meier survival curves demonstrated that patients with elevated AST and AST/ALT levels had a higher risk of developing severe COVID-19.

Conclusion: Elevated AST and AST/ALT levels correlated with severity of COVID-19 and mortality. Liver function tests may help clinicians in determining the prognosis of patients undergoing treatment for COVID-19.

Currently, deacetylated chitin (chitosan) nanoparticles (CNPs) are successfully utilized in aquaculture practices. This trial demonstrates the efficacy of CNPs in combating diazinon (DZN) toxicity in African catfish, Clarias gariepinus, via monitoring hepato-renal function, serum immune trait, hormonal function, and hepato-renal antioxidant activity. Four groups were allocated as follows: a control group, a CNPs group (0.

Influence of puberty on high intensity exercise induced skeletal muscle damage and inflammatory response in sedentary boys.

Sports and Exercise Physiology Laboratory, Department of Physiology, University of Calcutta, University Colleges of Sciences and Technology, 92 A.P.C. Road, Kolkata, 700009, India.

The present investigation examined the influence of age and pubertal transition on magnitude of muscle damage and inflammatory response following high intensity incremental treadmill running till volitional exhaustion in sixty-four sedentary prepubertal ( ​= ​32) and postpubertal ( ​= ​32) boys who were randomly recruited in the study. Muscle damage and inflammatory markers like creatine kinase (CK), lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotranferase (AST), C-Reactive Protein (CRP) and Interleukin-6 (IL-6) were estimated before and after exercise. Serum CK, LDH, AST, ALT, CRP and IL-6 levels significantly increased after exercise in both the groups in comparison to respective pre-exercise values.

Objective: This study aimed to investigate how dynamic contrast-enhanced CT imaging signs correlate with the differentiation grade and microvascular invasion (MVI) of hepatocellular carcinoma (HCC), and to assess their predictive value for MVI when combined with clinical characteristics.

Methods: We conducted a retrospective analysis of clinical data from 232 patients diagnosed with HCC at our hospital between 2021 and 2022. All patients underwent preoperative enhanced CT scans, laboratory tests, and postoperative pathological examinations.
