Pediatric CKD Progression Linked to Low Serum Bicarbonate

Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance. Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. More...

Presepsin Values Evaluated as Sepsis Severity Markers

Sepsis is a life-threatening condition, with poor and highly variable clinical manifestations, difficult to identify and diagnose. Sepsis has remained a real diagnostic challenge to clinicians, causing millions of death worldwide each year. Early recognition of sepsis is crucial for better disease outcome. More...

Pregnancy TSH Variations Prompt Erroneous Thyroid Disease Diagnosis

Thyroid-stimulating hormone is a pituitary hormone that stimulates the thyroid gland to produce thyroxine, and then triiodothyronine which stimulates the metabolism of almost every tissue in the body. More...

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...
