To evaluate the association between hypovitaminosis D and outcomes of symptom severity, mood disorders, fatigue, and quality of life in fibromyalgia (FM) patients. ⋯ Hypovitaminosis D may be a risk factor for worse symptom severity, anxiety, and depression in FM patients.

The analysis of particular (electroencephalographic) EEG frequency bands has revealed new insights relative to the neural dynamics that, when studying the EEG spectrum as a whole, would have remained hidden. This study is aimed at characterizing spectral resting state EEG patterns for assessing possible differences of episodic and chronic migraine during the interictal period. For that purpose, a novel methodology for analyzing specific frequencies of interest was performed. ⋯ Specific frequency bands were proposed to identify the spectral characteristics of the electrical brain activity in migraine during the interictal stage. Our findings support the importance of discriminating between migraine subgroups to avoid hiding relevant features in migraine.

Persistent vulvovaginal pain affects many women and often has adverse effects on sexual functioning. Psychological inflexibility related to pain is associated with distress and functional disability across different types of chronic pain conditions, but little is known about the role of psychological inflexibility in vulvovaginal pain. The present study examines psychological inflexibility related to pain as a predictor of sexual functioning over time among women with vulvovaginal pain. ⋯ The findings provide preliminary evidence that psychological inflexibility is associated with sexual adjustment over time among women with vulvovaginal pain and point to the relevance of further examinations of the psychological inflexibility model in the context of vulvovaginal pain.

Exercise is recommended to promote and maintain health and as treatment for more than 25 diseases and pain conditions. Exercise-induced hypoalgesia (EIH), a measure of descending pain inhibitory control, has been found to be impaired in some chronic pain conditions, but it is currently unclear if EIH is modifiable. This study investigated whether a long-term exercise intervention could modulate EIH in healthy subjects. ⋯ MT increased EIH, especially in subjects who demonstrated a hyperalgesic response at baseline. Improvement in physical performance capacity was associated with an improvement in EIH, indicating that improvement in physical performance capacity may improve central pain mechanisms.
