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...

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...

Two Serodiagnostic Tests Compared for Loiasis in Non-Endemic Area

Loiasis, the disease caused by the infection with the filarial nematode Loa loa, is transmitted through the bite of tabanid flies of the genus Chrysops. It is endemic in Central and West Africa where, according to the most recent estimates, about 10 million people are infected. More...

Increasingly Efficient Serological Tests Developed with Electrochemiluminescence

Diagnostic markers, or biomarkers, are biomolecules (e.g., enzymes, proteins, peptides, and hormones) that can be measured accurately and reproducibly and can precisely predict relevant clinical outcomes or diseases in various populations. More...

Tumor Mutation and Immune Microenvironment Revealed in Colorectal Cancer

Most colorectal cancers are due to old age and lifestyle factors, with only a small number of cases due to underlying genetic disorders. Other risk factors include diet, obesity, smoking, and lack of physical activity. Dietary factors that increase the risk include red meat, processed meat, and alcohol. More...

Serological Exposure Markers Developed for Vivax Malaria

Plasmodium vivax is the most widespread malaria parasite worldwide, with up to two billion people at risk of infection. As well as causing illness and death in its 'active' stage of infection, the parasite can hide as hypnozoites, a dormant stage, in the liver, and is a significant cause of 'relapsing' malaria. 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...
