Serum Biomarkers

Polyendocrine Metabolic Ovarian Syndrome (PMOS) is a common endocrine and metabolic disorder associated with insulin resistance, hyperandrogenism, and an increased risk of long-term metabolic complications. Fetuin-A and resistin are adipokines implicated in insulin resistance and chronic inflammation and may serve as potential biomarkers for metabolic dysfunction in women with PMOS. This prospective observational case-control study aims to compare serum and salivary Fetuin-A and resistin levels between women with PMOS and healthy controls. The study will evaluate the correlation between serum and salivary biomarker concentrations and investigate their associations with insulin resistance, lipid profile, and hormonal parameters. The findings may help determine whether salivary measurements can serve as reliable non-invasive biomarkers for the diagnosis and metabolic assessment of PMOS.

This is a pilot clinical study designed to evaluate the effects of a dietary supplement on selected blood-based nutritional biomarkers in healthy children aged 4 to 15 years. Approximately 24 children will be screened and enrolled to account for potential dropouts, with a target of 20 participants completing the study. Eligible participants will attend a screening and baseline visit, followed by daily intake of the study supplement for 4 weeks. After the supplementation period, participants will return to the clinic for an end-of-study visit. Blood samples will be collected at baseline and after 4 weeks to measure nutritional biomarkers, including vitamin D, vitamin B12, folate, omega-3 fatty acids, and standard blood count parameters. Additional assessments include height, weight, body mass index (BMI), and a socioeconomic questionnaire. Throughout the study, participants or their caregivers will record daily supplement intake, any medications taken, and any adverse events in a study diary. The results of this pilot study will provide preliminary data on the effects of the dietary supplement on serum biomarkers in children.
