Methods of determining infection type are disclosed. In one embodiment, the method comprises measuring the amount of TRAIL and/or IP10 no more than two days from symptom onset.

The current disclosure provides use of high dose nicotinamide adenine dinucleotide (NAD) precursor regimens for reduction of inflammation in human patients with preexisting inflammation. The NAD precursor can be nicotinamide riboside (NR) and the high dose regimen can include at least 1000 or 2000 mg/day for at least 9 days.

The invention provides methods of identifying schizophrenia patients at risk for relapse. The invention also provides methods of early detection of schizophrenic relapse. The disclosed methods use monitoring of a subset of symptoms and/or one or more biomarkers. The symptom severity can be assessed using the Positive and Negative Syndrome Scale (PANSS) parameters. The methods of the invention can be used to provide early intervention to decrease or prevent relapse in schizophrenia patients.

Disclosed herein are methods for treating subjects having rheumatoid arthritis (RA) with a human anti-interleukin 6 (IL-6) antibody, or antigen-binding portion thereof.

The present invention relates to the quantification of various biomarkers, including MMP9 (Inflammatory marker), LOX (Lysyl oxidase), IL6 (Interleukin-6), TNFα (tumor necrosis factor alpha), VEGF (Vascular Endothelial Growth Factor) ICAM-1 (Intercellular Adhesion Molecule-1) in aqueous humor, vitreous humor, tear and serum of patients with ocular diseases. The invention further describes the role of biomarkers in the pathogenesis, progression of ocular diseases. Hence, the level of biomarkers serves as a diagnostic and/or prognostic marker in ocular diseases. The invention further relates to the use of multiple biomarkers that can be simultaneously used for testing various corneal and retinal diseases.

Provided is a nanosensor having a high dynamic range and sensitivity for detecting the presence, and/or quantifying the amount, of an analyte in a sample of interest. Also provided is a cartridge incorporating the nanosensor, and a method and system for detecting the presence, and/or quantifying the amount, of the analyte in the sample of interest.

The present disclosure relates to exosomal complement mediators, cytokines, and mitochondrial electron transport biomarkers and diagnostic and prognostic methods for depression, psychosis and schizophrenia. The disclosure also provides compositions for detecting exosomal complement mediators, cytokines, and mitochondrial electron transport biomarkers in biological samples as well as compositions and methods useful for treating depression, psychosis and schizophrenia.

The invention provides methods of identifying schizophrenia patients at risk for relapse. The invention also provides methods of early detection of schizophrenic relapse. The disclosed methods use monitoring of a subset of symptoms and/or one or more biomarkers. The symptom severity can be assessed using the Positive and Negative Syndrome Scale (PANSS) parameters. The methods of the invention can be used to provide early intervention to decrease or prevent relapse in schizophrenia patients.

Provided herein are methods for reducing risk of severe symptoms and outcomes associated with Coronavirus Disease 2019 (COVID-19) and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection by measuring levels of interleukin 6 (IL-6), IL-8, IL-22, and serum ferritin in a subject. Also provided are methods for treating a subject exposed to or at elevated risk of expose to SARS-CoV-2 based on levels of IL-6, IL-8, IL-22, and ferritin in the serum of the subject.

The disclosure provides, inter alia, methods of detecting IL-6 signaling activity in T cells in breast cancer patients, such as breast cancer patients in remission.
