Changes in migraine characteristics over 30 days of Ramadan fasting: A prospective study.

OBJECTIVE: To study Ramadan's effect on migraine from the start to the end of the month and the tolerability of patients with migraine to fasting. BACKGROUND: Fasting is a well-known trigger for migraine. Whether this effect on migraine is the same throughout the whole month, or whether it varies from the first to the last days of the month, has not been studied yet. METHODS: A prospective cohort observational study was carried out on persons with migraine who fasted from 24 April to 23 May during Ramadan 2020. Each patient was asked to fill out their headache diary starting from Shaaban (the month before Ramadan) to the end of Ramadan. The Ramadan diary was divided by 10 days each, by which the patient was asked to accurately describe their migraine attacks in terms of frequency, duration, and intensity by using the Visual Analog Scale. Migraine attacks during the first day of fasting were assessed separately. RESULTS: A total of 292 known persons with migraine from Egypt completed the study. Their median age was 33 years; 72/292 (24.7%) were male, and 220/292 (75.3%) were female. About 126/236 (53.4%) of the patients had migraine attacks on Ramadan's first day, most of them during fasting. The frequency of migraine attacks was significantly increased in Ramadan (median 4, interquartile range [IQR] 2-7) compared with Shaaban (median 3, IQR 1-6), p = 0.009. The number of attacks was significantly reduced in both the second (median 1, IQR 0-2.25) and the third 10 days of Ramadan (median 1, IQR 1-3) compared with the first 10 days (median 3, IQR 1-5) (p < 0.001 for each). CONCLUSION: Ramadan's potential exacerbating effect on the frequency of migraine attacks should be discussed with patients with migraine. This effect appears to be limited to the first 10 days of Ramadan and then subsides with successive days of fasting.

Matrix Metalloproteinase-9 and Recovery of Acute Ischemic Stroke.

BACKGROUND: Stroke outcome can be predicted by clinical features, biochemical parameters, and some risk factors. Matrix metalloproteinase-9 (MMP-9) is involved in various stages of stroke pathology. MMP-9 inhibitors are potential stroke therapeutic agents. Little is known about the relation between MMP-9-after the acute stage-and clinical recovery. OBJECTIVE: The study aimed to investigate the serum level of MMP-9 at stroke onset as predictor of stroke outcome and the relation between the level of MMP-9 after 30 days and stroke recovery. METHODS: The National Institutes of Health Stroke Scale, modified Rankin Scale, and serum level of MMP-9 were assessed in 30 patients with acute ischemic stroke during the first 24 hours of onset and then a month later. None of the patients received thrombolytic therapy. Thirty normal volunteers of matched age and sex were included in the control group. RESULTS: The serum level of MMP-9 at stroke onset was independently positively correlated with stroke outcome. The serum level of MMP-9 30 days after stroke onset was positively correlated with initial stroke severity and outcome, as well as with clinical recovery. CONCLUSION: Higher serum level of MMP-9 at stroke onset can be a predictor of poor stroke outcome. However, beyond the acute stage, MMP-9 may play beneficial role in stroke recovery.
