Exhaled Nitric Oxide and Eosinophil Count Diagnose Eosinophilic Asthma

Eosinophilic asthma is now recognized as an important subphenotype of asthma based on the pattern of inflammatory cellular infiltrate in the airway. Eosinophilic asthma can be associated with increased asthma severity, atopy, late-onset disease, and steroid refractoriness. More...

Leptomeningeal Disease Diagnosed Using CSF Cell-Free DNA

Leptomeningeal disease (LMD) is a devastating complication of solid and liquid systemic and central nervous system malignant neoplasms. LMD, in which cancer metastasizes to the cerebrospinal fluid, occurs in 4% to 15% of cancer patients and is associated with poor survival, with untreated patients dying within four to six weeks.

Biomarker p-120 Catenin Distinguishes Conventional Urothelial Carcinoma from Variants

Plasmacytoid urothelial carcinoma (PC-UC) is an infrequent and clinically aggressive variant of urothelial carcinoma (UC). Initially, PC-UC was identified based on morphology as a potential mimicker of malignant plasma cell and lymphoid neoplasms and is characterized by loss of E-cadherin (E-Cad)–mediated intercellular adhesion.

Novel Blood-Based Test Bolsters MRI-Based Prostate Cancer Screening

Prostate cancer does not usually cause any symptoms until the cancer has grown large enough to put pressure on the tube that carries urine from the bladder out of the penis (urethra). Symptoms of prostate cancer can include: needing to urinate more frequently, often during the night needing to rush to the toilet. More...

Key Factors Signal Infection Risk in Alcoholic Hepatitis

Alcohol-associated hepatitis (AAH) is a severe form of liver injury with mortality as high as 30%-40% at 90 days. As a result of altered immune function in AAH, bacterial infections are common and are associated with poor outcomes. More...

Genomes of Advanced Neuroendocrine Neoplasms Unveil Subtypes

Metastatic and locally-advanced neuroendocrine neoplasms (aNEN) form clinically and genetically heterogeneous malignancies, characterized by distinct prognoses based upon primary tumor localization, functionality, grade, proliferation index and diverse outcomes to treatment. More...

Multitarget Fecal Immunochemical Test Validated for Colorectal Cancer

Colorectal cancer (CRC) starts in the colon or the rectum. These cancers can also be called colon cancer or rectal cancer, depending on where they start. Colon cancer and rectal cancer are often grouped together because they have many features in common. More...
