Biomarkers Evaluated for Lung Disease Severity in Cystic Fibrosis

Cystic fibrosis (CF) is one of the most common life-shortening monogenic disorders amongst European-derived populations currently affecting more than 85,000 patients worldwide. The diagnosis of CF is based on consensus clinical and laboratory criteria. More...

Metabolite Profiling Reveals Predictive Biomarkers for Amyotrophic Lateral Sclerosis

Amyotrophic Lateral Sclerosis (ALS) is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. It may begin with weakness in the arms or legs, or with difficulty speaking or swallowing. More...

Serum Free Thiols Predict Cardiovascular Events

Cardiovascular disease (CVD) is among the leading causes of morbidity and mortality globally, and during the past decade, the number of CVD-associated deaths has increased by 12.5%. Free thiols associate with favorable disease outcomes in many patient cohorts, and the current hypothesis is that oxidative stress might also play an important role in cardiovascular disease. More...

Urine Testing Method Developed for Ureterolithiasis

Ureterolithiasis (nephrolithiasis or kidney stones) is a disease affecting the urinary tract. Kidney stones occur due to buildup of certain salts and minerals that form crystals, which in turn stick together and enlarge to form a hard mass in the kidneys. The stones move into the urinary tract and can cause blood in the urine, considerable pain and blockages in the urinary system. More...

Glucose Levels Linked to Maternal Mortality Even in Non-Diabetic Women

The prevalence of diabetes mellitus (DM) and obesity have rapidly increased worldwide. Serum glycated hemoglobin A1c (HbA1c), expressed as an absolute percent (e.g., 5.5%), offers a convenient and representative measure of average blood glucose control among individuals with DM. More...

Endogenous Testosterone Levels Associated with Risk of Diabetes

High plasma levels of endogenous total and circulating free testosterone are associated with a two- to sevenfold increased risk for developing type 2 diabetes among young, healthy women without comorbidities. More...

Biomarkers Evaluated in Children with Community-Acquired Pneumonia

Community acquired pneumonia (CAP) is one of the most common conditions treated by pediatricians, yet predicting disease severity and prognosis is often difficult at the initial presentation. More...
