Clinical importance of laboratory biomarkers in liver fibrosis

Hepatic cirrhosis is a major health problem across the world, causing high morbidity and mortality. This disease has many etiologies, yet the result of chronic hepatic injury is hepatic fibrosis causing cirrhosis and hepatocellular carcinoma, as the liver’s architecture is progressively destroyed. While liver biopsy is currently the gold standard for fibrosis staging, it has significant disadvan...

Diagnostic role of urine human epididymis protein 4 in ovarian cancer

Urine human epididymis protein 4 (HE4) is a promising, non-invasive tumor marker for ovarian cancer (OC), offering advantages in early detection and monitoring. Studies show urine HE4 concentrations are higher than serum levels, with comparable sensitivity and specificity for detecting OC. It can aid in the differential diagnosis, monitor chemotherapy response, and track disease recurrence. Howeve...

Affordable Biologics for All

To paraphrase something that Mark Twain is alleged to have said, “Everybody talks about drug prices, but nobody does anything about them.” The last part of the paraphrase is not quite accurate, but to date, none of the major federal proposals to lower drug prices have been enacted, and state legislation, such as the California Preserving Access to Affordable Drugs Act, is under legal challenge...

Is the Environment Associated With Preterm Birth?

The study by Zhang et al. explores the link between preconception exposure to phthalates and an increased risk of preterm birth. Phthalates, commonly found in food and consumer products, are endocrine disruptors. The research found that higher concentrations of specific phthalate metabolites in maternal urine were associated with a 50% increased risk of preterm birth. The findings suggest that int...

Single Hormone Receptor–Positive Breast Cancer—Signal or Noise?

Canonical predictors for the prognosis of breast cancer include estrogen receptor (ER), progesterone receptor (PR), and ERBB2 (formerly HER2) receptor. In most cases, positive ER status is auspicious, but there are exceptions (young women, black women, and BRCA2 mutation carriers). The simplest designation, hormone receptor–positive cancers, includes tumors that express ER and/or PR (hormone rec...
