Use of Prophylactic or Therapeutic Anticoagulation in Critically Ill Patients With Pre-existing Atrial Fibrillation.

The optimal anticoagulation regimen for atrial fibrillation (AF) in critically ill patients is challenging as these patients may be at an increased risk for bleeding and clotting despite an absence or presence of anticoagulation. The purpose of this study was to compare bleeding and thrombotic rates in critically-ill adults with pre-existing AF receiving therapeutic anticoagulation versus chemical or mechanical venous thromboembolism prophylaxis. A retrospective, observational study was conducted.

The Differentiation between Progressive Disease and Treatment-Induced Effects with Perfusion-Weighted Arterial Spin-Labeling in High-Grade Gliomas.

Background And Purpose: Treatment-induced effects are difficult to differentiate from progressive disease in radiologically progressing diffuse gliomas after treatment. This retrospective, single-center cohort study investigated the diagnostic value of arterial spin-labeling perfusion in differentiating progressive disease from treatment-induced effects in irradiated patients with a high-grade glioma.

Materials And Methods: Adults with a high-grade glioma diagnosed between January 1, 2012, and December 31, 2018, with a new or increasing contrast-enhancing lesion after radiotherapy with or without chemotherapy and arterial spin-labeling were consecutively included.

Quantification of Hydrogen Isotopes Utilizing Raman Spectroscopy Paired with Chemometric Analysis for Application across Multiple Systems.

Online and real-time analysis of a chemical process is a major analytical challenge that can drastically change the way the chemical industry or chemical research operates. With analyses, a new and powerful understanding of chemistry can be gained; however, building robust tools for long-term monitoring faces many challenges, including compensating for instrument drift, instrument replacement, and sensor or probe replacement. Accounting for these changes by recollecting calibration data and rebuilding quantification models can be costly and time-consuming.

Clinical significance of the anti-Nucleolar Organizer Region 90 antibodies (NOR90) in systemic sclerosis: Analysis of the European Scleroderma Trials and Research (EUSTAR) cohort and a systematic literature review.

Background: The anti-Nucleolar Organizer Region 90 antibodies (NOR90) are rare antinuclear antibodies (ANA) reported in systemic sclerosis (SSc). Especially due to low prevalence, the clinical relevance of NOR90 in SSc remains uncertain.

Objectives: To analyze the clinical associations of NOR90 in patients with SSc in a multicentric cohort.

Efficacy of methylprednisolone in very early systemic sclerosis: results of the "Hit hard and early'' randomized controlled trial.

Objective: We hypothesized that glucocorticoids would induce remission in very early Systemic Sclerosis patients by inhibition of inflammation driving the disease. We examined the efficacy and safety of methylprednisolone in very early Systemic Sclerosis.

Methods: In this trial adults with puffy fingers for less than three years, specific auto-antibodies and meeting the Very Early Diagnosis of Systemic Sclerosis criteria were randomly assigned (2:1) to methylprednisolone 1000 mg intravenously or placebo for 3 consecutive days 3 times with monthly intervals.
