Background: The association between migraine and suicide ideation has been identified. However, the predictive factors of suicidal ideation are still controversial and whether migraine with aura can serve as an independent associated factor is uncertain. This manuscript studied the association between migraine with aura and suicidal ideation and explored the predictive factors for suicidal ideation.Methods: We surveyed 9,057 medical students and included 579 medical students with migraine into our study population. All students completed the General Situation Questionnaire, the Verified Headache Questionnaire, Hamilton Anxiety Scale (24 items), Hamilton Depression Scale (24 items), 36-item Health Survey Brief (SF-36), Headache Impact Text-6 (HIT-6), Test Anxiety Scale (TAS), and Pittsburgh Sleep Quality Index (PSQI). Suicidal ideation was measured by the Self-rating Idea of Suicide Scale (SIOSS).Results: Out of the 579 migraine medical college students, 562 (age 19.6 ± 1.6; 448 women and 114 men) were included in the final study. The positive rate of suicidal ideation was 13.7%. Compared with students suffering from migraine without aura, those having migraine with aura had higher suicidal ideation (p < 0.015). After adjusting for demographic factors and headache characteristics, migraine with aura was found to be independently associated with suicidal ideation. Other independent associated factors include anxiety, depression, test anxiety, sleep, headache, and quality of life. Among these various factors, high quality of life was found to play a protective role against suicidal ideation.Conclusions: Migraine with aura is independently associated with suicidal ideation. Furthermore, anxiety, depression, text anxiety, poor sleep quality, and headache frequency are associated with suicidal ideation among medical college students with migraine.
Objective As one of the most common primary headaches in clinical practice, migraine affects the learning ability and life quality of college students worldwide, posing a heavy burden on individuals and society. This study aims to investigate the incidence of migraine among Chinese medical college students and to explore its characteristics and typical triggers. Method From July 2019 to July 2020, North Sichuan Medical College in Sichuan province, China preliminarily screened migraine cases using ID-Migraine through cluster sampling. College students with positive ID-Migraine results would be included in this study if they were further diagnosed with migraine by neurologists based on ICHD-3. After the ethical review, patients’ personal and headache information would be collected, and the frequency, severity, onset time, and related triggers of migraine would be measured. Results The preliminary screening covered 8783 college students. The overall prevalence rate of migraine is 6.57%, 5.90% in men and 6.77% in women. The prevalence rate of migraine is higher for students in the first and second grades (8.01%, 8.05%), and students with a family history of migraine are more likely to suffer from migraine (OR = 1.509, 95% CI 1.060–2.148, P = 0.022 < 0.005). Staying up late (n = 329, 57.01%), stress (n = 319, 55.29%), catch a cold (n = 313, 54.25%) and sleep disorders (n = 302, 52.34%) are the common triggers. Conclusion Migraine is common among college students in North Sichuan Medical College. The incidence is higher among lower grade students, female students, and students with a family history of migraine. Improving sleep quality and reducing stress may be effective in relieving migraines.
The aim of this study was to research the mechanism of proprotein convertase subtilisin-like kexin type 9 (PCSK9) inhibitor in neural protective effect on rat cerebral ischemic reperfusion injury (I/RI). The transient middle cerebral artery occlusion (tMCAO) model of rats was prepared by the suture method, and PCSK9 inhibitor was injected intraperitoneally immediately after I/R. The rats were scored for neurological deficits and the cerebral infarction volume was measured. The brain tissues were collected and western blot (WB) was used to detect the expression of PCSK9. The rat cortical neural stem cells were treated with oxygen glucose deprivation (OGD) to establish a cell model of ischemia/reperfusion. WB was used to detect the expression of PCSK9 and the apoptosis-related pathway proteins. After interfering with the expression of PCSK9 siRNA, the cell viability (cell counting kit-8 assay) and apoptosis (TUNEL staining, Annexin V/PI method) were detected, and the cell proliferation was detected by EdU staining and flow cytometry. The expression of PCSK9 in the brain tissue of the MCAO group was dramatically increased. PCSK9 inhibitor can improve neurobehavioral scores and reduce apoptosis and infarct volume. An OGD model of neural stem cells in vitro was constructed. Inhibiting PCSK9 with si-PCSK9 can increase cell viability, promote cell proliferation, and also reduce cell apoptosis. Inhibition of PCSK9 can decrease the cerebral infarct volume in rats with cerebral I/RI and improve the neural function. Mechanically, inhibition of PCSK9 can lead to the decrease of nerve cell apoptosis and promotion of cell proliferation.
