Article Abstract
Duck enteritis virus (DEV), goose parvovirus (GPV), and muscovy duck parvovirus (MDPV) all have similar symptoms after infection, such as severe diarrhea, which seriously affects the healthy development of the waterfowl industry. Hence, it is important to devise a rapid and precise assay for the detection of these three viruses. In this study, a TaqMan probe-based multi-quantitative polymerase chain reaction (qPCR) assay was developed and optimized. Three specific primers and probes were designed according to the conserved regions of UL6 of DEV, REP of GPV, and VP1 of MDPV, respectively. DEV demonstrated a detection limit of 11.6 copies, GPV detected a limit of 95 copies, and MDPV showcased a detection limit of 14.8 copies. The correlation coefficient is greater than 0.99, and the amplification efficiency is 89% to 93%. These results indicate that the multiplex qPCR assay has high sensitivity, specificity, and stability. Of the 215 clinical samples used in this study, 33 tested DEV positive, 25 tested GPV positive, and 24 tested MDPV positive. Overall, the assay established in the current study presents a rapid, efficient, specific, and sensitive tool for of detecting DEV, GPV, and MDPV.

Severe pneumonia, as a critical and prevalent condition of the respiratory system, poses a significant threat to patient survival and health outcomes. This article focuses on the similarities and differences between community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP)/ventilator-associated pneumonia (VAP). There is significant divergence in the predominant pathogens between severe community-acquired pneumonia (SCAP) and HAP/VAP.

Background: The expression and clinical correlation of BRAFV600E mutation and programmed cell death-1 ligand 1 (PD-L1) in children with Langerhans cell histiocytosis (LCH) have been reported, but the conclusions of previous studies are inconsistent. In addition, it has been reported that elevated cathepsin S (CTSS) expression is associated with various cancers. However, there is currently no research on the correlation between CTSS and LCH.

A considerable number of individuals are diagnosed with idiopathic trigeminal neuralgia. In order to achieve a more complete understanding of the pathophysiology, it is essential to adopt a range of novel approaches and utilize new animal models. This study investigated changes in the messenger RNA (mRNA) expression of ion-channels in a newly developed animal model of trigeminal neuropathic pain induced by cervical spinal dorsal horn compression.

Background: Obesity was a risk factor for severe COVID-19 in children during early outbreaks of ancestral SARS-CoV-2 and the Delta variant. However, the relationship between obesity and COVID-19 severity during the Omicron wave remains unclear.
Methods: This multicenter, observational study included polymerase chain r eaction-confirmed SARS-CoV-2-infected children and adolescents from Australia, Brazil, Italy, Portugal, Switzerland, Thailand, the United Kingdom and the United States hospitalized between January 1, 2020, and March 31, 2022.
