چکیده

AbstractBackground COVID-19 has been associated with Interstitial Lung Disease features. The immune transcriptomic overlap between Idiopathic Pulmonary Fibrosis (IPF) and not investigated. Methods we analyzed blood transcript levels of 50 genes known to predict IPF mortality in three two cohorts. Scoring Algorithm Molecular Subphenotypes (SAMS) was applied distinguish high versus low-risk profiles all SAMS cutoffs derived from the Discovery cohort were used intensive care unit (ICU) status, need for mechanical ventilation, in-hospital Validation cohort. A Single-cell RNA-sequencing identify cellular sources 50-gene risk profiles. same Findings discriminated severe mild (P = 0·015) predicted ICU admission, (AUC: 0·77, 0·75, 0·74, respectively, P < 0·001) In COVID-19, expressing cells a high-risk profile included monocytes, dendritic cells, neutrophils, while profile-expressing CD4+, CD8+ T lymphocytes, IgG producing plasmablasts, B NK, gamma/delta cells. Same also predictive University Chicago (HR:5·26, 95%CI:1·81–15·27, 0·0013) Imperial College London (HR:4·31, 95%CI:1·81–10·23, 0·0016) Interpretation peripheral outcomes. these gene expression changes suggest common innate adaptive responses both diseases.

Outcomes of Surgical Decompression for Spinal Metastases from Gynecological Cancers: A Retrospective Cohort Study

BACKGROUND & AIM: Gynecological cancer is one of the most common types of cancer worldwide. Nonetheless, spinal metastasis from gynecological cancer is scarcely reported in the literature. In cases of spinal cord compression, the standard treatment is a decompressive surgery followed by radiotherapy treatment for selected patients. This study aimed to report the overall survival and surgical re...

In Vitro Maturation of Oocytes in Women at Risk of Ovarian Hyperstimulation Syndrome-A Prospective Multicenter Cohort Study

Objective In vitro maturation (IVM) is an artificial reproductive technology in which immature oocytes are harvested from the ovaries and subsequently matured in vitro. IVM does not require ovarian hyperstimulation and thus the risk of ovarian hyperstimulation syndrome (OHSS) is avoided. In this multicenter prospective cohort study we assessed the live birth rate per initiated in vitro maturati...

Comparison of Alcohol Withdrawal Outcomes in Patients Treated with Benzodiazepines Alone versus Adjunctive Phenobarbital: a Retrospective Cohort Study

Background: For treatment of severe alcohol withdrawal syndrome, high dose benzodiazepines (BZDs) may cause delirium and over-sedation. Phenobarbital (PBT) is a long-acting barbiturate effective for the treatment of alcohol withdrawal. Given the potential benefits of PBT, we sought to investigate the effectiveness of PBT as adjunctive treatment for alcohol withdrawal. Methods: This was a retros...
