The examination and assessment of injured and ill patients leads to the establishment of a diagnosis. However, the tests and procedures used in health care, including procedures performed by certified athletic trainers, are individually and collectively imperfect in confirming or ruling out a condition of concern. Thus, research into the utility of diagnostic tests is needed to identify the procedures that are most helpful and to indicate the confidence one should place in the results of the test. The purpose of this report is to provide an overview of selected statistical procedures and the interpretation of data appropriate for assessing the utility of diagnostic tests with dichotomous (positive or negative) outcomes, with particular attention to the interpretation of sensitivity and specificity estimates and the reporting of confidence intervals around likelihood ratio estimates.

Quantification of Citrullinated Histone H3 as a Marker for Neutrophil Extracellular Traps Correlated to Clinical Characteristics of Patients with Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease whose pathogenesis is not fully understood to date. One of the suggested mechanisms for its development is NETosis, which involves the release of a specific network consisting of chromatin, proteins, and enzymes from neutrophils, stimulating the immune system. One of its markers is citrullinated histone H3 (H3Cit).

Objectives: To characterize the serum cytokine profile in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) at onset and during follow-up and assess their utility for predicting relapses and disability.
Methods: This retrospective multicentric cohort study included patients aged 16 years and older meeting MOGAD 2023 criteria, with serum samples collected at baseline (≤3 months from disease onset) and follow-up (≥6 months from the baseline), and age-matched and time to sampling-matched patients with multiple sclerosis (MS). Eleven cytokines were assessed using the ELLA system.
Explainable Machine Learning to Predict Treatment Response in Advanced Non-Small Cell Lung Cancer.

Emory University School of Medicine, Atlanta, GA.
Purpose: Immune checkpoint inhibitors (ICIs) have demonstrated promise in the treatment of various cancers. Single-drug ICI therapy (immuno-oncology [IO] monotherapy) that targets PD-L1 is the standard of care in patients with advanced non-small cell lung cancer (NSCLC) with PD-L1 expression ≥50%. We sought to find out if a machine learning (ML) algorithm can perform better as a predictive biomarker than PD-L1 alone.

Purpose: Continuous EEG (cEEG) monitoring is increasingly used in the management of neonates with seizures. There remains debate on what clinically relevant information can be gained from cEEG in neonates with suspected seizures, at high risk for seizures, or with definite seizures, as well as the use of cEEG for prognosis in a variety of conditions. In this guideline, we address these questions using American Clinical Neurophysiology Society structured methodology for clinical guideline development.

Purpose: Phenylephrine testing prior to Müller muscle conjunctival resection has traditionally been used to predict postoperative outcomes. The purpose of this study is to determine if preoperative phenylephrine testing impacts postoperative changes in eyelid position.
Methods: In this multicenter cross-sectional cohort study, 270 eyelids of participants with involutional ptosis and levator function >12 mm who underwent Müller muscle conjunctival resection were divided into 2 comparison groups.
