Article Abstract
Background: The aim of this study was to investigate the relationship between Age, immunoglobin G (IgG), immunoglobin M (IgM), procalcitonin (PCT), and interleukin-6 (IL6), and the time to clear viral nucleic acids in asymptomatic and mild coronavirus disease 2019 (COVID-19) patients, as well as evaluated the predictive value of these biochemical indicators.
Methods: We performed a retrospective analysis on 1,570 individuals who were admitted to Tianjin First Central Hospital and diagnosed with asymptomatic or mild cases. Laboratory data were collected, including age, gender, levels of IgG, IgM, PCT and IL6, as well as results of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) nucleic acid test. These data were statistically analyzed using SPSS software, version 24.0.
Results: The results indicated that among mild patients, Age, IgG, and the time to clear viral nucleic acids were higher than asymptomatic patients ( < 0.05). And the time to clear viral nucleic acids was significantly correlated with Age, IgG, IgM, PCT, and IL6 ( < 0.05), IgG ( = -0.445, < 0.001) showed moderate correlations. Using logistic regression analysis, we identified older age, high IL6 levels, and low IgG levels were risk factors for nucleic acid clearance exceeding 14 days ( < 0.05). When combining these three indicators to predict the probability of nucleic acid clearance exceeding 14 days in the 1,570 patients, the AUROC was found to be 0.727.
Conclusion: Age, IgG, and IL6 could potentially serve as useful predictors for nucleic acid clearance exceeding 14 days in asymptomatic and mild COVID-19 patients.

Background: Mixed-phenotype acute leukemia (MPAL) is a rare acute leukemia for which data are currently not available to guide therapy. It has a poor outcome, particularly in elderly patients.
Case Presentation: We report the successful use of venetoclax/azacitidine as treatment for a treatment-naive elderly patient with early T-cell precursor (ETP)/myeloid MPAL.

This report presents the case of a 36-year-old man complaining of chronic low back pain and numbness along the posterolateral surface of the right leg. Magnetic resonance imaging (MRI) revealed a disc degeneration and protrusion at the L-S level and an extensive fluid-equivalent formation with a craniocaudal dimension of 8 cm at the S-S level. Initially, due to the minimal clinical complaints, the cyst was considered asymptomatic.

Background The prognostic value of baseline visual emphysema scoring at low-dose CT (LDCT) in lung cancer screening cohorts is unknown. Purpose To determine whether a single visual emphysema score at LDCT is predictive of 25-year mortality from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease (CVD). Materials and Methods In this prospective cohort study, asymptomatic adults aged 40-85 years with a history of smoking underwent baseline LDCT screening for lung cancer between June 2000 and December 2008.

Since its discovery, the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), has become the epicenter of public health concern. This was mainly attributed to the complexity of COVID-19 that resulted in variable disease progression with some developing asymptomatic infections, some suffering mild to moderate infections that resolved without the need for hospitalizations, and a few infected persons developing severe infections that required intensive care unit (ICU) admission and mechanical ventilation. The COVID-19 pandemic spread globally, affecting billions of people and killing millions.

Background: Paragangliomas (PGLs) are rare neuroendocrine tumors originating from the extra-adrenal autonomic paraganglia with a strong genetic background. pathogenic variants are associated with the highest rate of malignancy in PGLs. Most head and neck paragangliomas (HNPGs) are asymptomatic and benign, and multiple metastases are rare.
