Cortisol and polycystic ovarian syndrome - a systematic search and meta-analysis of case-control studies.

Background: Polycystic ovarian syndrome (PCOS) has become an emerging disorder affecting women of reproductive age group. Its intricate presentation of signs and symptoms makes it a disease of interest to research. While there are varied hypotheses related to its cause and pathogenesis, role of stress in this disease is yet to be grounded.

Computerized dynamic pupillometry as a screening tool for evaluation of autonomic activity.

Objectives: Dynamic pupillometry is a simple screening tool for quantifying pupillary light reflex (PLR), to indicate autonomic nervous system (ANS) activity. Heart rate variability (HRV) is the gold standard method for assessing ANS effects on the heart. The present study aimed to compare ANS activity as measured using dynamic pupillometry (DP) with short term HRV in healthy volunteers.
