Review Meta Analysis
Epidemiological linkage between migraine and diabetes mellitus: a systematic review and meta-analysis.
This study aimed to elucidate the nature and extent of the associations between diabetes mellitus (DM) and migraine through a systematic review and meta-analysis. ⋯ DM, particularly type 1 diabetes, is negatively associated with migraine occurrence, whereas migraine, especially MO, is positively associated with DM occurrence. However, most of the results remained at a low or very low level of evidence, indicating the need for further research.

Review Meta Analysis
Resting-state electroencephalography and magnetoencephalography in migraine-a systematic review and meta-analysis.
Magnetoencephalography/electroencephalography (M/EEG) can provide insights into migraine pathophysiology and help develop clinically valuable biomarkers. To integrate and summarize the existing evidence on changes in brain function in migraine, we performed a systematic review and meta-analysis (PROSPERO CRD42021272622) of resting-state M/EEG findings in migraine. We included 27 studies after searching MEDLINE, Web of Science Core Collection, and EMBASE. ⋯ Moreover, some evidence for higher delta and beta power in the premonitory compared to the interictal phase was found. Strongest risk of bias of included studies arose from a lack of controlling for comorbidities and non-automatized or non-blinded M/EEG assessments. These findings can guide future M/EEG studies on migraine pathophysiology and brain-based biomarkers, which should consider comorbidities and aim for standardized, collaborative approaches.

About a quarter of migraine cases among women have menstrual migraine (MM), which is usually more severe, longer lasting, and less responsive to treatment than typical migraine. Randomized controlled trials (RCTs) have evaluated the efficacy of several medication in the acute and preventive treatment of MM; this meta-analysis compared the effectiveness of these treatments. ⋯ Sumatriptan and lasmiditan are effective first-line treatments for acute MM. For prevention, frovatriptan may be the more effective of triptans. Compared with triptans, CGRP monoclonal antibodies, here including erenumab and galcanezumab, are more effective in reducing headache days, and therefore, in preventing MM.
