Is exercise duration more important than intensity in endometriosis?
Hartmann et al.
The finding, in our words
In women with endometriosis, longer individual exercise sessions were associated with lower levels of salivary c-reactive protein and estradiol, as well as reduced pain and fat mass. The results demonstrate the utility of timed, at-home saliva self-collection for assessing systemic biomarkers in reproductive health research.

This study used home self-collected saliva samples to successfully monitor cytokines and cortisol in mothers and infants, finding that a community singing intervention significantly reduced salivary interleukin-6 levels in mothers with postnatal depression.

In a study of 46 perinatal nicotine users, dried blood spots and saliva were used weekly to measure reproductive hormones, finding that lower postpartum estradiol and greater peripartum declines in oxytocin were associated with increased nicotine craving and use. This demonstrates the feasibility of decentralised microsampling and remote surveys for longitudinal hormone tracking in vulnerable populations.

Cortisol dynamic range measured from participant-led saliva collection was feasible and associated with higher perceived stress and anxiety in African American women, suggesting saliva self-collection can serve as a decentralised biomarker of chronic stress.

In 60 healthy young adults who self-collected saliva, habitual coffee consumption at low, moderate or high intake did not significantly alter morning or evening levels of salivary cortisol or alpha amylase under non-stressful conditions. This suggests that for decentralised diagnostics, coffee drinking is unlikely to confound salivary hormone results, supporting the validity of self-collection for cortisol and stress biomarker monitoring.

In sixteen workers observed during the COVID-19 pandemic, those working from home had higher waking and lower nocturnal melatonin, and higher oxytocin, than office-based colleagues, while cortisol and s-IgA rhythms were unchanged. The study shows that self-collected saliva samples can detect how remote work alters stress-related biomarkers, supporting decentralised occupational-health monitoring.
