Background: Migraine is a disabling neurological disorder whose diagnosis is based on clinical criteria. A shortcoming of these criteria is that they do not fully capture the underlying neurobiological factors and sex-specific complications in migraine such as cardio- and cerebrovascular disease. Biomarker research can help to improve disease characterization and identify pathophysiological mechanism underlying these comorbidities. Objective: In this narrative review we searched for sex-specific metabolomics research to identify markers that may explain the migraine-cardiovascular disease (CVD) relationship. Discussion: Large-scale plasma metabolome analyses revealed alterations in migraine. Sex-specific findings showed a less CVD-protective HDL metabolism as well as the ApoA1 lipoprotein, especially for women with migraine. To explore other possible pathophysiological pathways, we expanded our review to include inflammatory markers, endothelial and vascular markers and sex hormones. Biological sex differences may affect the pathophysiology of migraine and its complications. Conclusions: There is no general large dyslipidemia profile in migraine patients, in line with findings that the increased risk of CVD in migraine patients seems not to be due to (large artery) atherosclerosis. Sex-specific associations are indicative towards a less CVD-protective lipoprotein profile in women with migraine. Future studies into the pathophysiology of CVD and migraine need to take sex specific factors into account. By establishing the overlapping pathophysiological mechanism of migraine and CVD, and unraveling the associated effects these diseases exert on each other, better preventative measures can be identified. Key points : • There is no general large dyslipidemia profile in migraine patients, in line with findings that the increased risk of CVD in migraine patients seems not to be due to (large artery) atherosclerosis. • Sex-specific associations are indicative towards a less CVD-protective lipoprotein profile in women with migraine. • Future studies into the pathophysiology of CVD and migraine need to take sex specific factors into account.

Objective:To investigate: (1) the course of coronary heart disease risk factors (lipid profiles and body mass index (BMI)) in the first five years after discharge from inpatient spinal cord injury (SCI) rehabilitation and (2) the association between lifestyle (physical activity, self-care related to fitness, smoking, alcohol, body mass and low-fat diet) and coronary heart disease risk factors during that period.Design:Prospective cohort study.Participants/methods:Individuals with SCI (N=130). Total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG) and BMI were determined at discharge from inpatient rehabilitation and 1 and 5 years after discharge. Using multilevel regression models, the effects of lifestyle (drinking alcohol, smoking, active lifestyle and self-care) on the lipid profiles and BMI were determined.Results:After correction for lesion and personal characteristics, no changes in lipid profiles in the five years after discharge were seen, whereas the BMI increased significantly with 1.8 kg m−2. A high percentage was at risk of cardiovascular disease due to high BMI (63-75%) or HDL (66-95%). The individuals who indicated to maintain their fitness level as good as possible and the individuals with a low BMI showed better lipid profiles. Individuals with a more active lifestyle showed higher HDL levels. Individuals who avoid smoking showed a 1.5 kg m−2 higher BMI.Conclusion:Lipid profiles seem to stabilize in the years after discharge from inpatient SCI rehabilitation, whereas the BMI increased. Lifestyle factors associated with a favorable lipid profile and BMI could be identified. [ABSTRACT FROM AUTHOR]

Study design:A prospective cohort study.Objectives:To study the longitudinal relationship between objectively measured everyday physical activity level, and physical fitness and lipid profile in persons with a recent spinal cord injury (SCI).Setting:A rehabilitation centre in the Netherlands and the participant's home environment.Methods:Data of 30 persons with a recent SCI were collected at the start of active rehabilitation, 3 months later, at discharge from inpatient rehabilitation, and 1 year after discharge. Physical activity level (duration of dynamic activities as % of 24 h) was measured with an accelerometry-based activity monitor. Regarding physical fitness, peak oxygen uptake (VO2peak) and peak power output (POpeak) were determined with a maximal wheelchair exercise test, and upper extremity muscle strength was measured with a handheld dynamometer. Fasting blood samples were taken to determine the lipid profile.Results:An increase in physical activity level was significantly related to an increase in VO2peak and POpeak, and an increase in physical activity level favourably affected the lipid profile. A nonsignificant relation was found with muscle strength.Conclusion:Everyday physical activity seems to have an important role in the fitness and health of persons with a recent SCI. An increase in physical activity level was associated with an increase in physical fitness and with a lower risk of cardiovascular disease. [ABSTRACT FROM AUTHOR]

Study design:A multicenter prospective cohort study.Objective:To determine the longitudinal relationship between physical capacity and lipid profile in persons with spinal cord injury (SCI) during and 1 year after rehabilitation.Setting:Eight Dutch rehabilitation centers with a specialized SCI unit.Methods:A total of 206 subjects with SCI (78 with tetraplegia) participated. The longitudinal relationship between lipid profiles (total cholesterol (TC), high- (HDL) and low-density lipoprotein (LDL) and triglycerides (TG) and physical capacity (peak power output (POpeak), peak oxygen uptake (VO2peak), and muscle strength) was investigated during inpatient SCI rehabilitation (start, 3 months later, discharge) and 1 year after discharge. A correction was made for the possible confounding variables age, body mass index, gender, time since injury, lesion level and completeness.Results:HDL and the ratios LDL/HDL and TC/HDL showed a significant and favorable relationship with VO2peak, POpeak and muscle strength. TG was positively related to POpeak and muscle strength.Conclusions:More favorable lipid profiles were seen in people with a higher physical capacity after correction for personal and lesion characteristics. Therefore, improving the physical capacity by being active during daily life or in sport may further improve the lipid profile and thus reduce the risk for coronary heart disease.Spinal Cord (2008) 46, 344–351; doi:10.1038/sj.sc.3102147; published online 20 November 2007 [ABSTRACT FROM AUTHOR]
