Migraine is a risk factor for hypertensive disorders in pregnancy: a prospective cohort study

How migraine and its associated treatment impact on pregnancy outcomes: Umbrella review with updated systematic review and meta-analysis

BACKGROUND

Migraine is common in reproductive aged women. Understanding the impact of migraine and associated treatments on pregnancy outcomes remains very important. An umbrella review of systematic reviews, with or without meta-analyses, examined the link between migraine and pregnancy outcomes.

METHODS

We systematically searched Medline, Embase and Cochrane to 27 October 2022. Quality appraisal was carried out using the AMSTAR2 tool. An established framework was used to determine whether included reviews were eligible for update.

RESULTS

Four studies met review criteria. Migraine was reported to be associated with increased odds ratio (OR) of pre-eclampsia, low birth weight and peripartum mental illness (pooled OR = 3.54 (2.24-5.59)). Triptan-exposed women had increased odds of miscarriage compared to women without migraine (pooled OR = 3.54 (2.24-5.59)). In updated meta-analyses, migraine was associated with an increased odds of pre-eclampsia and preterm birth (pooled OR = 2.05 (1.47-2.84) and 1.26 (1.21-1.32) respectively).

CONCLUSIONS

Migraine is associated with increased odds of pre-eclampsia, peripartum mental illness and preterm birth. Further investigation of the relationship between migraine and placental abruption, low birth weight and small for gestational age is warranted, as well as the relationship between migraine, triptans and miscarriage risk.Systematic Review Registration: Prospero CRD42022357630.

Migraine and cardiovascular disease: what cardiologists should know

Migraine is a chronic neurovascular disease with a complex, not fully understood pathophysiology with multiple causes. People with migraine suffer from recurrent moderate to severe headache attacks varying from 4 to 72 h. The prevalence of migraine is two to three times higher in women compared with men. Importantly, it is the most disabling disease in women <50 years of age due to a high number of years lived with disability, resulting in a very high global socioeconomic burden. Robust evidence exists on the association between migraine with aura and increased incidence of cardiovascular disease (CVD), in particular ischaemic stroke. People with migraine with aura have an increased risk of atrial fibrillation, myocardial infarction, and cardiovascular death compared with those without migraine. Ongoing studies investigate the relation between migraine and angina with non-obstructive coronary arteries and migraine patients with patent foramen ovale. Medication for the treatment of migraine can be preventative medication, such as beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, antiepileptics, antidepressants, some of the long-acting calcitonin gene-related peptide receptor antagonists, or monoclonal antibodies against calcitonin gene-related peptide or its receptor, or acute medication, such as triptans and calcitonin gene-related peptide receptor antagonists. However, these medications might raise concerns when migraine patients also have CVD due to possible (coronary) side effects. Specifically, knowledge gaps remain for the contraindication to newer treatments for migraine. All cardiologists will encounter patients with CVD and migraine. This state-of-the-art review will outline the basic pathophysiology of migraine and the associations between migraine and CVD, discuss current therapies, and propose future directions for research.

History of maternal migraine and its association with preeclampsia: A case-control study in a low-resource setting in Sudan, Africa

BACKGROUND

Previous studies have reported various levels of association between migraine and preeclampsia. However, there are no published data on migraine and its association with preeclampsia in African countries, including Sudan.

METHODS

A case-control study was conducted at Rabak Maternity Hospital in White Nile State, Central Sudan. The cases were pregnant women with preeclampsia, while the controls were healthy pregnant women. All participants were interviewed using questionnaire. The adjusted odds ratio (AOR) and a 95% confidence interval (CI) were calculated in a multivariate regression analysis.

RESULTS

Of 148 pregnant women with preeclampsia, 96 (64.9%) women had mild preeclampsia and 52 (35.1%) women had severe preeclampsia. Of the 148 study participants with preeclampsia, 57 (38.5%) had a history of migraine and 19/296 (6.4%) women in control group had a history of migraine (p < 0.001). Pregnant women with a history of migraine have higher odds of preeclampsia than pregnant women without a history of migraine (AOR = 9.01, 95% CI = 4.81-16.86). A history of preeclampsia, being overweight and obesity were associated with preeclampsia.

CONCLUSION

Our findings are consistent with the findings of previous studies on the association between migraine and preeclampsia. More studies are needed on this topic.

Association of Migraine and Vasomotor Symptoms

OBJECTIVE

To further examine a potential link between migraine and vasomotor symptoms as well as hypertension as a cardiovascular disease risk factor, potentially explaining the association in midlife women.

PATIENTS AND METHODS

We conducted a cross-sectional analysis from the Data Registry on Experiences of Aging, Menopause, and Sexuality using questionnaire data from women aged 45 to 60 years seen in women's clinics at a tertiary care center from May 15, 2015, through January 31, 2022. A history of migraine was self-reported; menopause symptoms were assessed with the Menopause Rating Scale. Associations between migraine and vasomotor symptoms were evaluated utilizing multivariable logistic regression models adjusting for multiple factors.

RESULTS

Of 5708 women included in the analysis, 1354 (23.7%) reported a migraine history. The total cohort had a mean age of 52.8 years, most (5184 [90.8%]) were White, and 3348 (58.7%) were postmenopausal. In adjusted analysis, women with migraine were significantly more likely to have severe/very severe hot flashes vs no hot flashes compared with women without migraine (odds ratio, 1.34; 95% CI, 1.08 to 1.66; P=.007). Migraine was associated with a diagnosis of hypertension in adjusted analysis (odds ratio, 1.31; 95% CI, 1.11 to 1.55; P=.002).

CONCLUSION

This large cross-sectional study confirms an association between migraine and vasomotor symptoms. Migraine also was associated with hypertension, potentially providing a link with cardiovascular disease risk. Given the high prevalence of migraine in women, this association may help identify those at risk for more severe menopause symptoms.

Prepregnancy Migraine, Migraine Phenotype, and Risk of Adverse Pregnancy Outcomes

BACKGROUND AND OBJECTIVE

Migraine is a highly prevalent neurovascular disorder among reproductive-aged women. Whether migraine history and migraine phenotype might serve as clinically useful markers of obstetric risk is not clear. The primary objective of this study was to examine associations of prepregnancy migraine and migraine phenotype with risks of adverse pregnancy outcomes.

METHODS

We estimated associations of self-reported physician-diagnosed migraine and migraine phenotype with adverse pregnancy outcomes in the prospective Nurses' Health Study II (1989-2009). Log-binomial and log-Poisson models with generalized estimating equations were used to estimate relative risks (RRs) and 95% CIs for gestational diabetes mellitus (GDM), preeclampsia, gestational hypertension, preterm delivery, and low birthweight.

RESULTS

The analysis included 30,555 incident pregnancies after cohort enrollment among 19,694 participants without a history of cardiovascular disease, diabetes, or cancer. After adjusting for age, adiposity, and other health and behavioral factors, prepregnancy migraine (11%) was associated with higher risks of preterm delivery (RR = 1.17; 95% CI = 1.05-1.30), gestational hypertension (RR = 1.28; 95% CI = 1.11-1.48), and preeclampsia (RR = 1.40; 95% CI = 1.19-1.65) compared with no migraine. Migraine was not associated with low birthweight (RR = 0.99; 95% CI = 0.85-1.16) or GDM (RR = 1.05; 95% CI = 0.91-1.22). Risk of preeclampsia was somewhat higher among participants with migraine with aura (RR vs no migraine = 1.51; 95% CI = 1.22-1.88) than migraine without aura (RR vs no migraine = 1.30; 95% CI = 1.04-1.61; p-heterogeneity = 0.32), whereas other outcomes were similar by migraine phenotype. Participants with migraine who reported regular prepregnancy aspirin use had lower risks of preterm delivery (<2×/week RR = 1.24; 95% CI = 1.11-1.38; ≥2×/week RR = 0.55; 95% CI = 0.35-0.86; p-interaction < 0.01) and preeclampsia (<2×/week RR = 1.48; 95% CI = 1.25-1.75; ≥2×/week RR = 1.10; 95% CI = 0.62-1.96; p-interaction = 0.39); however, power for these stratified analyses was limited.

DISCUSSION

Migraine history, and to a lesser extent migraine phenotype, appear to be important considerations in obstetric risk assessment and management. Future research should determine whether aspirin prophylaxis may be beneficial for preventing adverse pregnancy outcomes among pregnant individuals with a history of migraine.

Migraine and risk of hypertensive disorders of pregnancy: A population-based cohort study

BACKGROUND

Migraine is associated with hypertensive disorders of pregnancy through common pathophysiological features. This study evaluates the association between migraine diagnosis and treatment, and risk of hypertensive disorders of pregnancy.

METHODS

We conducted a prospective cohort study in the Clinical Practice Research Datalink GOLD, a large longitudinal database of patient records in the UK. We analyzed data from liveborn or stillborn singleton deliveries from 1993-2020 with at least 24 months of medical history and no history of cardiovascular disease (n = 1,049,839). We ascertained migraine through diagnosis or prescription codes before 20 weeks of gestation and hypertensive disorders of pregnancy through diagnosis codes between 20 weeks of pregnancy and delivery. We used log-binomial regression models to estimate the risk ratio and 95% confidence intervals, comparing risk of hypertensive disorders of pregnancy among individuals with migraine to those without migraine, adjusting for confounders.

CONCLUSIONS

A history of migraine prior to pregnancy was associated with an increased risk of hypertensive disorders of pregnancy (RR = 1.17, 95% CI: 1.09-1.26). The greatest risk was among those with pre-pregnancy migraine that persisted into the first trimester (RR = 1.84, 95% CI: 1.35-2.50). Use of migraine medication was associated with a higher risk of hypertensive disorders of pregnancy compared to non-migraineurs (RR = 1.50, 95% CI: 1.15-1.97). Results from this study indicate that migraine is a potential risk factor for hypertensive disorders of pregnancy.

Migraine treatment in pregnancy: A survey of comfort and treatment practices of women's healthcare providers

OBJECTIVE

The objective of this study was to assess women's healthcare providers' treatment practices for pregnant women with migraine.

BACKGROUND

Migraine is associated with several maternal and fetal complications during pregnancy, including preeclampsia and preterm birth. Migraine treatment during pregnancy can present significant challenges due to lack of controlled clinical trials and risks associated with specific medications.

METHODS

Women's healthcare providers were queried regarding practice patterns and comfort with use of acute and preventive migraine treatments during pregnancy. The survey was distributed online.

RESULTS

The survey was completed by 92 women's healthcare providers (response rate 22.9% [92/402]), with most specializing in general obstetrics and gynecology (91% [83/92]). Approximately one-fourth (26% [24/92]) of respondents indicated they counseled women on migraine treatment in pregnancy as early as before pregnancy contemplation, while over one-third (35% [32/92]) counseled on migraine treatment once the patient became pregnant. The majority of respondents reported feeling somewhat or very comfortable with recommending (63% [58/92]) or continuing (64% [59/92]) acute treatments for pregnant patients with migraine, with highest comfort levels for acetaminophen (100% [92/92] for prescribing or continuing) and caffeine (94% [85/90] prescribing, 91% [82/90] continuing). Higher levels of discomfort were reported with triptans (88% [80/91] rarely or never prescribe during pregnancy). Survey respondents felt less comfortable with recommending preventive migraine treatments to pregnant patients (40% [37/92] somewhat or very comfortable), compared with a higher comfort level with continuing preventive medications (63% [58/92] somewhat or very comfortable). Highest comfort levels were reported with use of magnesium (69% [63/91] comfortable prescribing, 82% [75/92] comfortable continuing) and non-pharmacologic approaches (70% [62/89] comfortable prescribing, 84% [75/89] comfortable continuing). Nearly 40% (35/92) of respondents reported that they typically refer to neurologists or headache specialists for migraine treatment during pregnancy.

CONCLUSION

This survey of women's healthcare providers revealed varying levels of comfort regarding migraine management during pregnancy, and highlights the need for additional education regarding migraine treatment safety data during pregnancy.

Migraine

Migraine affects about 1 billion people worldwide, and up to 15% of adults in the United States have migraine attacks in any given year. Migraine is associated with substantial adverse socioeconomic and personal effects. It is the second leading cause of years lived with disability worldwide for all ages and the leading cause in women aged 15 to 49 years. Diagnostic uncertainty increases the likelihood of unnecessary investigations and suboptimal management. This article advises clinicians about diagnosing migraine, ruling out secondary headache disorders, developing acute and preventive treatment plans, and deciding when to refer the patient to a specialist.

First-trimester prediction model for placental vascular disorders: An observational prospective study

This study aims to develop a multivariable predictive model for the risk of placental vascular complications (PVC), by using biochemical, biophysical, anamnestic and clinical maternal features available at the first trimester. PVC include gestational hypertension, preeclampsia, placenta abruption, intrauterine growth restriction (IUGR), and stillbirth. Prospective study that included all singleton pregnancies attending the first-trimester aneuploidy screening (11 +0-12 +6 weeks) at Obstetrics Unit of the University Hospital of Modena, in Northern Italy, between June 2018 and December 2019. In a total of 503 women included in the analysis, 40 patients were in the PVC group. The final prediction model for PVC included the following independent variables: pre-pregnancy BMI ≥ 30 (OR = 2.65, 95% CI = 1.04; 6.75, p = 0.0415), increasing values of mean arterial pressure (OR = 1.06, 95% CI = 1.02; 1.10, p = 0.0008), PAPP-A < 2.40465 U/L (OR = 0.43, 95% CI = 0.19; 0.96, p = 0.0388) and decreasing values of PlGf (MoM) (OR = 0.28, 95% CI = 0.10; 0.79, p = 0.0153). The area under the ROC curve was 79.4% indicating a satisfactory predictive accuracy. The best predictive cut-off for this score was equal to -2.562, which corresponds to a 7.2 % probability of having PVC. By using such a cut-off, the risk of PVC can be predicted in our sample with sensitivity equal to 82,4 % and specificity equal to 69,9 %. This model for early prediction of PVC is a promising tool to early identify women at greater risk for placenta vascular complications.

Headaches in Pregnancy and Postpartum: ACOG Clinical Practice Guideline No. 3

PURPOSE

To provide updated evidence-based recommendations for the evaluation and treatment of primary and secondary headaches in pregnancy and postpartum.

TARGET POPULATION

Pregnant and postpartum patients with a history of or experiencing primary or new secondary headaches.

METHODS

This guideline was developed using an a priori protocol in conjunction with a writing team consisting of two specialists in obstetrics and gynecology appointed by the ACOG Committee on Clinical Practice Guidelines-Obstetrics and one external subject matter expert. ACOG medical librarians completed a comprehensive literature search for primary literature within Cochrane Library, Cochrane Collaboration Registry of Controlled Trials, EMBASE, PubMed, and MEDLINE. Studies that moved forward to the full-text screening stage were assessed by two authors from the writing team based on standardized inclusion and exclusion criteria. Included studies underwent quality assessment, and a modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) evidence-to-decision framework was applied to interpret and translate the evidence into recommendation statements.

RECOMMENDATIONS

This Clinical Practice Guideline includes recommendations on interventions to prevent primary headache in individuals who are pregnant or attempting to become pregnant, postpartum, or breastfeeding; evaluation for symptomatic patients presenting with primary and secondary headaches during pregnancy; and treatment options for primary and secondary headaches during pregnancy and lactation. Recommendations are classified by strength and evidence quality. Ungraded Good Practice Points are included to provide guidance when a formal recommendation could not be made because of inadequate or nonexistent evidence.

Prescribing for pregnancy: managing chronic headache and migraine

Globally, headache disorders are an important cause of disability in adults. As many types of headache (eg, migraine, tension-type and medication-overuse) are more common in women and have peak incidence in reproductive years, chronic headache disorders are highly prevalent in pregnant women. Some women with a history of migraine may find that it improves during pregnancy while others may find that their migraines become more unpredictable. Ideally, women with migraine and problematic headache disorder should be offered preconception counselling to address pregnancy-related concerns and advice on the use of medicines, which should be supported by high-quality information. For women with history of headache, the use of effective non-pharmacological options should be maximised, and the smallest number of the safest medicines at the lowest effective doses should be used while preparing for pregnancy and during pregnancy. This article forms part of the series of prescribing for pregnancy and discusses the impact of headache and migraine on pregnancy, the impact of pregnancy on headache and migraine and options for prophylaxis and treatment.

Randomized Controlled Trials of Headache Treatments in Pregnancy: A Systematic Review

OBJECTIVE

Headaches affect 88% of reproductive-aged women. Yet data are limited addressing treatment of headache in pregnancy. While many women experience improvement in pregnancy, primary and secondary headaches can develop. Consequently, pregnancy is a time when headache diagnosis can influence maternal and fetal interventions. This study was aimed to summarize existing randomized control trials (RCTs) addressing headache treatment in pregnancy.

STUDY DESIGN

We searched PubMed, CINAHL, EMBASE, ClinicalTrials.gov, Cochrane Library, CINAHL, and SCOPUS from January 1, 1970 through June 31, 2019. Studies were eligible if they were English-language RCTs addressing treatment of headache in pregnancy. Conference abstracts and studies investigating postpartum headache were excluded. Three authors reviewed English-language RCTs addressing treatment of antepartum headache. To be included, all authors agreed each article to meet the following criteria: predefined control group, participants underwent randomization, and treatment of headache occurred in the antepartum period. If inclusion criteria were met no exclusions were made. Our systematic review registration number was CRD42019135874.

RESULTS

A total of 193 studies were reviewed. Of the three that met inclusion criteria all were small, with follow-up designed to measure pain reduction and showed statistical significance.

CONCLUSION

Our systematic review of RCTs evaluating treatment of headache in pregnancy revealed only three studies. This paucity of data limits treatment, puts women at risk for worsening headache disorders, and delays diagnosis placing both the mother and fetus at risk for complications.

Perinatal outcomes in women affected by different types of headache disorders: A prospective cohort study

OBJECTIVE

This study aims to investigate pregnancy and perinatal outcomes in women with tension-type headache, migraine without aura and migraine with aura by comparing them to women without any headache disorders.

STUDY DESIGN

Prospective cohort study including singleton pregnancies attending the first trimester aneuploidy screening at the University Hospital of Modena, in Northern Italy, between June 2018 and December 2019.

RESULTS

A total of 515 consecutive women were included and headache disorders were reported in 43.5% of them (224/515). Tension-type headache was diagnosed in 24.3% of the cases, while 14% suffered from migraine without aura and 5.2% from migraine with aura. Birthweight was significantly lower in women affected by migraine with aura respective to other groups, and a significantly higher rate of small for gestational age infants was found in tension-type headache (10.4%) and in migraine with aura (24.9%) groups respective to the others (p < 0.001). Moreover, the admission to the neonatal intensive care unit was significantly higher in all the headache groups (p = 0.012). Multivariate analysis showed that women presenting tension-type headache (OR 4.19, p = 0.004), migraine with aura (OR 5.37, p = 0.02), a uterine artery pulsatility index >90th centile (OR 3.66, p = 0.01), low multiple of the median (MoM) of Pregnancy-associated plasma protein-A (PAPP-A) (OR 0.48, p = 0.05) and high MoM of Inhibin-A (OR 3.24, p = 0.03) at first trimester, are independently associated with the delivery of small for gestational age infants when compared to women without headache disorders.

CONCLUSION

Migraine with aura and tension type headache expose women to an increased risk of delivering small for gestational age infants, in association with some utero-placenta markers evaluated at first trimester. These women with headache disorders have an additional indication to undergo first trimester aneuploidy screening and would possibly benefit from specific interventions.

Headache in Women

PURPOSE OF REVIEW

Women are greatly overrepresented among patients seeking treatment for symptoms of headache pain in general and migraine in particular. Understanding the presentation of headache in women in relation to hormonal changes both during the menstrual cycle and throughout the life span is essential for appropriate diagnosis and treatment.

RECENT FINDINGS

Although perimenstrual migraine attacks are generally without aura, the diagnosis of migraine with aura has been added to the headache classification for menstrual migraine to account for women with the diagnosis of migraine with aura who experience menstrual migraine attacks. Emerging knowledge regarding the differences between menstrual and nonmenstrual attacks, the variability of attack triggering within and between women, and the response of women with menstrually related migraine to new migraine drug classes is contributing to better understanding and more effective treatment of these particularly burdensome and refractory attacks. Given the burden of migraine, almost one-fourth of women with migraine avoid or delay pregnancy. Women who experience migraine during pregnancy are more likely to have a hypertensive disorder and stroke during pregnancy and/or delivery and the postpartum period. Treatment of headache in general and migraine in particular in pregnancy is challenging because of fetal and maternal risks; however, a 2021 systematic review suggests that triptans and low-dose aspirin may not be associated with fetal/child adverse effects and could be more strongly considered for headache treatment in pregnancy.

SUMMARY

Headache in general and migraine in particular are extraordinarily common in women of reproductive age and fluctuate with hormonal changes and phases of life. Improved knowledge of the epidemiology, pathophysiology, and response to treatment of perimenstrual attacks is essential for more effective response to this most burdensome headache type. Treatment of headache in pregnancy remains challenging.

A Case-Control Study of Peripartum Cardiomyopathy Using the Rochester Epidemiology Project

Background:

The incidence of peripartum cardiomyopathy (PPCM) is known through referral center databases that may be affected by referral, misclassification, and other biases. We sought to determine the community-based incidence and natural history of PPCM using the Rochester Epidemiology Project.

Methods and Results:

Incident cases of PPCM occurring between January 1, 1970, and December 31, 2014, were identified in Olmsted County, Minnesota. A total of 15 PPCM cases were confirmed yielding an incidence of 20.3 cases per 100,000 live births in Olmsted County, Minnesota. Clinical information, disease characteristics, and outcomes were extracted from medical records in a 27-county region of the Rochester Epidemiology Project including Olmsted County and matched in a 1:2 ratio with pregnant women without PPCM. A total of 48 women were identified with PPCM in the expanded 27-county region. There was 1 death and no transplants over a median of 7.3 years of follow-up. Six of the 23 women with subsequent pregnancies developed recurrent PPCM, all of whom recovered. Migraine and anxiety were identified as novel possible risk factors for PPCM.

Conclusions:

The population-based incidence of PPCM was 20.3 cases per 100,000 live births in Olmsted County, Minnesota. Cardiovascular outcomes were generally excellent in this community cohort.

Headaches during pregnancy

Headache during pregnancy is frequent and challenging. A secondary headache is diagnosed in one third of women, and most causes are vascular and infectious disorders. Anamnestic and clinical features must be investigated, and brain imaging is often required. Primary headaches are commonly modified during pregnancy. Migraine is mainly improved in this context, especially migraine without aura. Particular cautions about treatment must be applied, and non-pharmacological measures must be preferred. Tension-type headache and cluster headache seem to be less hormone-dependent.

The Potential Protective Role of Aspirin Against Migraine in Pregnant Women

Females are highly predisposed to the occurrence of migraine, a recurrent neurovascular headache disorder. Although migraine improves or disappears during pregnancy, a significant association between migraine and hypertension (i.e., pre-eclampsia) or vascular complications (i.e., stroke) during gestation has been determined. Low-dose aspirin exerts an antithrombotic effect and can improve vascular resistance by regulating endothelial function, which are implicated in the pathogenesis of migraine, pre-eclampsia, and other vascular complications during pregnancy. Low-dose aspirin is widely used prophylactically in the general population who are at higher risk of developing stroke or in pregnant women at higher risk of pre-eclampsia. In this paper we discuss the recent trends in research on the relationship between migraine and pre-eclampsia, an issue of paramount importance in obstetric care, and the potential relationship between migraine and vascular complications in pregnant women. In addition, the potential validity of low-dose aspirin prophylaxis in pregnant women with migraine is explored.

Migraine: navigating the hormonal minefield

Migraine affects 959 million people worldwide,1 with the highest prevalence being in women of childbearing age. The interplay between female hormones and migraine can be a challenging area to navigate since issues relating to pregnancy, contraception and the menopause are often out of the neurology comfort zone. This review aims to help the neurologist to manage women with migraine, from menarche to menopause.

Migraine during pregnancy and in the puerperium

Pregnancy can be seen as a positive time for women migraineurs because the elevated estrogen and endogenous opioid levels raise the pain threshold and the stable hormone levels, which no longer fluctuate, eliminate a major trigger factor for the attacks. In a great majority of cases, indeed, migraine symptoms spontaneously improve throughout pregnancy. Generally, migraine without aura (MO) improves better than migraine with aura (MA), which can occur ex novo in pregnancy more frequently than MO. After childbirth, the recurrence rate of migraine attacks increases, especially during the first month; breastfeeding exerts a protective effect against the reappearance of attacks. Migraine and pregnancy share a condition of hypercoagulability; therefore, attention must be paid to the risk of cardiovascular disorders, like venous thromboembolism and ischemic or hemorrhagic strokes. Some of these diseases can be linked to preeclampsia (PE), a serious complication of pregnancy, characterized by hypertension, proteinuria, or other findings of organ failure. This condition is more common in migraineurs compared with non-migraineurs; furthermore, women whose migraines worsen during pregnancy had a 13-fold higher risk of hypertensive disorders than those in which migraine remitted or improved. Pregnancy is generally recognized to exert a beneficial effect on migraine; nonetheless, clinicians should be on the alert for possible cardiovascular complications that appear to be more frequent in this patient population.

[Migraine in women: clinical and therapeutical aspects]

Migraine is one of the most common neurological disorders, affecting women. Physiological changes in the hormonal status can modulate the functional status of pain and analgesic systems of the brain and, by involving different pathophysiological mechanisms, change the course of migraine. In addition to an analysis of epidemiological data, the review provides current views on the clinical features of the disease in women population at different periods of life, particular attention was focused on menstrual migraine. It has certain features, such as acute and long attacks and treatment difficulties. One of main issues is the use of oral contraceptives in women with migraine according to the ratio of potential benefit to cardiovascular risk. The problems of treatment headaches in pregnant and breastfeeding women are also considered. An influence of migraine on the course and outcome of pregnancy was shown. The authors analysed the results of the studies on the course of migraine during perimenopause and postmenopause and recommendations for women with migraine attacks and climacteric syndrome. The data presented in the review are useful for clinicians, because this information represents new views on pathogenetic mechanisms, clinical features and treatment of migraine in women.

Pregnancy, Birth, Neonatal, and Postnatal Neurological Outcomes After Pregnancy With Migraine

BACKGROUND

Prevalence of migraine is high during the reproductive age. Although migraine often improves during pregnancy, the risk of adverse pregnancy, birth, neonatal, and neurological outcomes in mother and offspring remains poorly understood.

OBJECTIVE

To investigate the associations between maternal migraine and risks of adverse pregnancy outcomes in the mother, and birth, neonatal and postnatal outcomes in the offspring.

METHODS

We used Danish population registries to assemble a cohort of pregnancies among women with migraine and an age- and conception year-matched comparison cohort of pregnancies among women without migraine. The study period was 2005-2012. We computed adjusted prevalence ratios (aPRs) for pregnancy and birth outcomes and adjusted risk ratios (aRRs) for neonatal and postnatal outcomes, adjusting for age, preconception medical history, and preconception reproductive history.

RESULTS

We identified 22,841 pregnancies among women with migraine and 228,324 matched pregnancies among women without migraine. Migraine was associated with an increased risk of pregnancy-associated hypertension disorders (aPR: 1.50 [95% confidence interval (CI): 1.39-1.61]) and miscarriage (aPR: 1.10 [95% CI: 1.05-1.15]). Migraine was associated with an increased prevalence of low birth weight (aPR: 1.14 [95% CI: 1.06-1.23]), preterm birth (aPR: 1.21 [95% CI: 1.13-1.30]) and cesarean delivery (aPR: 1.20 [95% CI: 1.15-1.25]), but not of small for gestational age offspring (aPR: 0.94 [95% CI: 0.88-0.99]) and birth defects (aPR: 1.01 [95% CI: 0.93-1.09]). Offspring prenatally exposed to maternal migraine had elevated risks of several outcomes in the neonatal and postnatal period, including intensive care unit admission (aRR: 1.22 [95% CI: 1.03-1.45]), hospitalization (aRR: 1.12 [95% CI: 1.06-1.18]), dispensed prescriptions (aRR: 1.34 [95% CI: 1.24-1.45]), respiratory distress syndrome (aRR: 1.20 [95% CI: 1.02-1.42]), and febrile seizures (aRR: 1.27 [95% CI: 1.03-1.57), but not of death (aRR: 0.67 [95% CI: 0.43-1.04]) and cerebral palsy (aRR: 1.00 [95% CI: 0.51-1.94]).

CONCLUSIONS

Women with migraine and their offspring have greater risks of several adverse pregnancy outcomes than women without migraine.

Serotonin-estrogen interactions: What can we learn from pregnancy?

We have reviewed the scientific literature related to four diseases in which to serotonin (5-HT) is involved in the etiology, herein named 5-HT-linked diseases, and whose prevalence is influenced by estrogenic status: depression, migraine, irritable bowel syndrome and eating disorders. These diseases all have in common a sex-dimorphic prevalence, with women more frequently affected than men. The co-occurrence between these 5-HT-linked diseases suggests that they have common physiopathological mechanisms. In most 5-HT-linked diseases (except for anorexia nervosa and irritable bowel syndrome), a decrease in the serotonergic tone is observed and estrogens are thought to contribute to the improvement of symptoms by stimulating the serotonergic system. Human pregnancy is characterized by a unique 5-HT and estrogen synthesis by the placenta. Pregnancy-specific disorders, such as hyperemesis gravidarum, gestational diabetes mellitus and pre-eclampsia, are associated with a hyperserotonergic state and decreased estrogen levels. Fetal programming of 5-HT-linked diseases is a complex phenomenon that involves notably fetal-sex differences, which suggest the implication of sex steroids. From a mechanistic point of view, we hypothesize that estrogens regulate the serotonergic system, resulting in a protective effect against 5-HT-linked diseases, but that, in turn, 5-HT affects estrogen synthesis in an attempt to retrieve homeostasis. These two processes (5-HT and estrogen biosynthesis) are crucial for successful pregnancy outcomes, and thus, a disruption of this 5-HT-estrogen relationship may explain pregnancy-specific pathologies or pregnancy complications associated with 5-HT-linked diseases.

The Hypertensive Headache: a Review

PURPOSE OF REVIEW

The purpose of this review is to provide an overview and update on the common causes of headache attributed to arterial hypertension with a focus on secondary headache disorders. We will also highlight uncommon and recent findings in this area of research.

RECENT FINDINGS

There is some controversy in the relationship between chronic hypertension and headache, particularly migraine; recent research suggests that there may be a link, but it is likely complex and multifactorial. Many recent studies and case reports demonstrate that the pathophysiology underlying the onset of headache as it relates to abrupt rises in blood pressure seems to lie at the cellular level and mechanically becomes an issue with disruption of the blood-brain barrier. Although not a formally defined headache entity, carotid revascularization syndrome demonstrates this phenomenon and also has a recent set of proposed criteria that include headache and elevated blood pressure. This paper reviews the various etiologies of hypertensive headaches, mostly in regard to headache as a secondary symptom of elevated blood pressure. We will also discuss trends of hypertensive headache in pregnancy. Finally, we will touch on controversy that exists in relation to chronic hypertension and its causal relationship to headache as well as the relationship between hypertension and migraine.

Estrogen, migraine, and vascular risk

Migraine has a predilection for female sex and the course of symptoms is influenced by life stage (presence of menstrual cycle, pregnancy, puerperium, menopause) and use of hormone therapy, such as hormonal contraception and hormone replacement therapy. Hormonal changes figure among common migraine triggers, especially sudden estrogen drop. Moreover, estrogens can modulate neuronal excitability, through serotonin, norepinephrine, dopamine, and endorphin regulation, and they interact with the vascular endothelium of the brain. The risk of vascular disease, and ischemic stroke in particular, is increased in women with migraine with aura (MA), but the link is unclear. One hypothesis posits for a causal association: migraine may cause clinical or subclinical brain lesions following repeated episodes of cortical spreading depression (CSD) and a second hypothesis that may explain the association between migraine and vascular diseases is the presence of common risk factors and comorbidities. Estrogens can play a differential role depending on their action on healthy or damaged endothelium, their endogenous or exogenous origin, and the duration of their treatment. Moreover, platelet activity is increased in migraineurs women, and it is further stimulated by estrogens.This review article describes the course of migraine during various life stages, with a special focus on its hormonal pathogenesis and the associated risk of vascular diseases.

Antidepressant use during pregnancy and the risk of developing gestational hypertension: a retrospective cohort study

BACKGROUND

Prior studies reported that exposure to antidepressants during pregnancy may be associated with gestational hypertension. The aim of this study is to assess the association between the use of antidepressants during pregnancy and the risk of developing gestational hypertension.

METHODS

A retrospective cohort study using the prescription database IADB.nl was conducted among nulliparous women with singleton pregnancies between 1994 and 2015 in the Netherlands. Logistic regression analysis was used to estimate odds ratios (OR), adjusted OR (aOR) and their corresponding 95% confidence intervals (95% CI). Gestational hypertension as main outcome measure was defined as at least one dispensed record of an antihypertensive drug (methyldopa, nifedipine, labetalol, ketanserin, nicardipine) after 20 weeks of gestation until 14 days after delivery. Sub-analyses were conducted for class of antidepressant, duration and amount of use of antidepressant (≤30, ≥30 Defined Daily Doses or DDDs), and maternal age. Sensitivity analyses to assess uncertainties were conducted.

RESULTS

Twenty-eight thousand twenty women were included, of which 539 (1.92%) used antidepressants. The risk of gestational hypertension was doubled for women using antidepressant (aOR 2.00 95% CI 1.28-3.13). Significant associations were also found for the subgroup selective serotonin reuptake inhibitors (SSRIs) (aOR 2.07 95% CI 1.25-3.44), ≥30 DDDs (aOR 2.50 95% CI 1.55-3.99) and maternal age of 30-34 years (aOR 2.59 95% CI 1.35-4.98). Varying the theoretical gestational age showed comparable results.

CONCLUSION

Prolonged use of antidepressants during the first 20 weeks of gestation appeared to be associated with an increased risk of developing gestational hypertension. When balancing the benefits and risks of using these drugs during pregnancy, this should be taken into account.

Current concepts in migraine and their relevance to pregnancy

The prevalence of migraine in women of childbearing age is high, estimated at 24%. Migraine management during pregnancy and lactation can be challenging. Our understanding of the way in which medications affect the unborn fetus is still incomplete and the evidence is constantly changing with more recent emphasis on longitudinal studies and childhood development. The aim of this article is to describe the relationship between migraine and pregnancy and review the current evidence on treatment options in pregnancy and lactation.

Chronic pain during pregnancy: a review of the literature

BACKGROUND AND PURPOSE

The majority of the reviews and studies on chronic pain in pregnancy have primarily focused on the pharmacological and non-pharmacological treatment options. The purpose of our review was to identify evidence-based clinical research for the evaluation and management of preexisting chronic pain in pregnancy, chronic pain associated with pregnancy, and chronic pain in relation to mode of delivery.

METHODS

A literature search was undertaken using the search engines PubMed, CINAHL, EBSCOhost, and Web of Science. Search terms used included "chronic pain" AND "pregnant OR pregnancy" OR "pregnancy complications" from inception through August 2016.

RESULTS

The basis of this review was the 144 articles that met inclusion criteria for this review. Based on our review of the current literature, we recommend 7 guidelines for chronic pain management during and after pregnancy: 1) complete history and physical examination; 2) monitor patients for alcohol, nicotine, and substance use; 3) collaborate with patient to set treatment goals; 4) develop a management plan; 5) for opioids, use lowest effective dose; 6) formulate a pain management plan for labor and delivery; and 7) discuss reproductive health with women with chronic pain.

CONCLUSION

The management of chronic pain associated with pregnancy is understudied. Obstetrical providers primarily manage chronic pain during pregnancy. Some general guidelines are provided for those health care providers until more information is available.

Female Sexual Dysfunction-Medical and Psychological Treatments, Committee 14

INTRODUCTION

Since the millennium we have witnessed significant strides in the science and treatment of female sexual dysfunction (FSD). This forward progress has included (i) the development of new theoretical models to describe healthy and dysfunctional sexual responses in women; (ii) alternative classification strategies of female sexual disorders; (iii) major advances in brain, hormonal, psychological, and interpersonal research focusing on etiologic factors and treatment approaches; (iv) strong and effective public advocacy for FSD; and (v) greater educational awareness of the impact of FSD on the woman and her partner.

AIMS

To review the literature and describe the best practices for assessing and treating women with hypoactive sexual desire disorder, female sexual arousal disorder, and female orgasmic disorders.

METHODS

The committee undertook a comprehensive review of the literature and discussion among themselves to determine the best assessment and treatment methods.

RESULTS

Using a biopsychosocial lens, the committee presents recommendations (with levels of evidence) for assessment and treatment of hypoactive sexual desire disorder, female sexual arousal disorder, and female orgasmic disorders.

CONCLUSION

The numerous significant strides in FSD that have occurred since the previous International Consultation of Sexual Medicine publications are reviewed in this article. Although evidence supports an integrated biopsychosocial approach to assessment and treatment of these disorders, the biological and psychological factors are artificially separated for review purposes. We recognize that best outcomes are achieved when all relevant factors are identified and addressed by the clinician and patient working together in concert (the sum is greater than the whole of its parts).

Headache and pregnancy: a systematic review

This systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic intracranial hypertension, and reversible cerebral vasoconstriction syndrome. Migraine is a risk factor for pregnancy complications, particularly vascular events. Data regarding other primary headache conditions are still scarce. Early diagnostics of the disease manifested by headache is important for mother and fetus life. It is especially important to identify “red flag symptoms” suggesting that headache is a symptom of a serious disease. In order to exclude a secondary headache additional studies can be necessary: electroencephalography, ultrasound of the vessels of the head and neck, brain MRI and MR angiography with contrast ophthalmoscopy and lumbar puncture. During pregnancy and breastfeeding the preferred therapeutic strategy for the treatment of primary headaches should always be a non-pharmacological one. Treatment should not be postponed as an undermanaged headache can lead to stress, sleep deprivation, depression and poor nutritional intake that in turn can have negative consequences for both mother and baby. Therefore, if non-pharmacological interventions seem inadequate, a well-considered choice should be made concerning the use of medication, taking into account all the benefits and possible risks.

Patterns and predictors of analgesic use in pregnancy: a longitudinal drug utilization study with special focus on women with migraine

Background

Few studies have investigated the drug utilization patterns and factors predicting drug use in pregnant women with migraine. This longitudinal drug utilization study aimed to describe patterns of analgesic use in a sample of Norwegian pregnant women according to their migraine history, and to identify predictors for analgesic use among these women.

Methods

Pregnant women giving birth at Akershus University Hospital between 2008 and 2010 were recruited at ultrasound examination in gestational week 17. Data were collected by questionnaires in gestational weeks 17 and 32, and at 8 weeks postpartum, and linked to birth records. Women were grouped into four categories according to migraine history: no migraine history, previous migraine history, recent migraine history (within 1 year prior to pregnancy) and migraine in pregnancy. Patterns of use of analgesics were analyzed descriptively. Multivariable logistic regression was used to identify factors predicting analgesic use.

Results

Out of 1981 women, 5.0% reported having migraine in pregnancy, 13.2% had a recent history of migraine, 11.5% had a previous history of migraine, and 68.8% reported no history of migraine. Analgesic use declined during pregnancy. Many women switched from triptans and non-steroidal anti-inflammatory drugs to paracetamol, which constituted most of the analgesic use. Factors associated with analgesic use included recent migraine history (OR 1.6, 95% CI 1.2–2.2), more severe headache intensity (OR 1.3, 95% CI 1.3–1.4), smoking (OR 1.9, 95% CI 1.1–3.3) and multiparity (OR 1.4, 95% CI 1.1–1.7).

Conclusions

Women with migraine stop or switch medications during pregnancy. Analgesic use in pregnancy is affected by migraine characteristics and intensity, and also by socio-demographic factors. Clinicians should bear this in mind when giving advice on adequate management of migraine in pregnancy and safe analgesic use.

Delivery Outcomes of Patients with Acute Migraine in Pregnancy: A Retrospective Study

OBJECTIVE

To describe labor and delivery outcomes in pregnant patients presenting to the hospital setting with an acute severe migraine headache attack earlier in the same gestation.

METHODS

We retrospectively reviewed pregnancy and delivery records from a database of consecutive inpatient neurology consultations for acute headache in pregnant women over a 5 year period.

RESULTS

We identified 86 pregnant women with acute migraine. The mean age was 29.3 (±6.4) years. Nearly half had migraine with aura (35/86 [40.7%]), 12.8% (12/86) had chronic migraine, and 31.4% (27/86) presented in status migrainosus. Complication rates included 54.7%([41/75], 95% CI 29.87, 52.13) for at least one adverse outcome, 28.0% ([21/75], 95% CI 11.78, 30.22) for preterm delivery, 21.3% ([16/75], 95% CI 7.7, 24.3) for preeclampsia, 30.6% ([23/75] 95% CI 13.48, 32.52) for cesarean delivery, and 18.7% ([14/75] 95% CI 6.15, 21.85) for low birthweight.

CONCLUSIONS

Pregnant women seeking treatment for acute migraine headache experienced a higher rate of preterm delivery, preeclampsia, and low birthweight but a lower rate of cesarean delivery than the local and general populations. More than half (54.7% [41/75] 95% CI 29.87, 52.13) of the study patients experienced some type of adverse birth outcome, suggesting that pregnancies in migraine patients presenting to an acute care setting may benefit from more intense surveillance.

Migraine and cardiovascular disease in women

Migraine is responsible for high rates of disability. In addition, it is associated with an increased risk of cardiovascular disease. This association is not limited to the brain in the form of stroke, but includes cardiac ischemia. The increased risk is most consistently described in the female population and in particular for migraine with aura. This article reviews the current knowledge on migraine and the associated risk of cardiovascular disease, with a focus on female-specific factors.

Managing Migraine During Pregnancy and Lactation

While over half of women with migraine report improvement during pregnancy, having a history of migraine may increase the chance of negative health outcomes. The state of pregnancy increases the risk of several dangerous secondary headache disorders, especially those associated with hypertensive disorders of pregnancy, and providers need to know the red flags to diagnose and treat emergently. Non-pharmacological migraine treatments can be instituted in advance of pregnancy as many are considered the safest options during pregnancy, but understanding the safety of medications and dietary supplements ensures appropriate care for the refractory migraine patient. New controversy exists over the safety of several historically routine and safe migraine treatment options in pregnancy, such as magnesium, acetaminophen, ondansetron, and butalbital. While it is not clear if breastfeeding decreases the postpartum recurrence of migraine, understanding safe treatment options during lactation can allow women to continue breastfeeding while achieving migraine relief.

Prenatal triptan exposure and parent-reported early childhood neurodevelopmental outcomes: an application of propensity score calibration to adjust for unmeasured confounding by migraine severity

PURPOSE

Triptan medications are serotonin agonists used to treat migraine, a chronic pain condition highly prevalent in women of reproductive age. Data on the safety of triptans during pregnancy are scant. We sought to quantify the association of prenatal triptan exposure on neurodevelopment in 3-year-old children.

METHODS

Using data from the Norwegian Mother and Child Cohort Study, we used propensity score matching to examine associations between prenatal triptan exposure and psychomotor function, communication, and temperament. We used an external validation study to perform propensity calibration to adjust effect estimates for confounders unmeasured in the main study (migraine severity, type, and maternal attitudes towards medication use).

RESULTS

We identified 4204 women who reported migraine headache at baseline, of which 375 (8.9%) reported using a triptan greater than or equal to once during pregnancy. Children with prenatal triptan exposure had 1.37-fold greater unadjusted odds of fine motor problems (95% confidence interval (CI): 1.06-1.77), which decreased after propensity score matching (odds ratio (OR): 1.29, 95%CI 0.97-1.73) and was further attenuated after calibration (OR: 1.25, 95%CI 0.89-1.74). We observed no increased risk for gross motor or communication problems, and no differences in temperament. Adjustment for migraine severity using propensity score calibration had a moderate impact on effect estimates, with percent changes ranging from 2.4% to 50%.

CONCLUSIONS

Prenatal triptan exposure was not associated with psychomotor function, communication problems, or temperament in 3-year-old children. Adjustment for migraine severity reduced effect estimates and should be considered in future studies of the safety of triptans during pregnancy. Copyright © 2015 John Wiley & Sons, Ltd.

Pharmacological treatment of migraine during pregnancy and breastfeeding

Migraine affects up to 25% of women of reproductive age. In the majority of these women, migraine improves progressively during pregnancy, but symptoms generally recur shortly after delivery. As suboptimally treated migraine in pregnancy could have negative consequences for both mother and fetus, the primary aim of clinicians should be to provide optimal treatment according to stage of pregnancy, while minimising possible risks related to drug therapy. Nonpharmacological approaches are always first-line treatment, and should also be used to complement any required drug treatment. Paracetamol is the preferred drug for acute treatment throughout pregnancy. If paracetamol is not sufficiently effective, sporadic use of sumatriptan can be considered. NSAIDs such as ibuprofen can also be used under certain circumstances, though their intake in the first and third trimesters is associated with specific risks and contraindications. Preventive treatment should only be considered in the most severe cases. In women contemplating pregnancy, counselling is essential to promote a safe and healthy pregnancy and postpartum period for the mother and child, and should involve a dialogue addressing maternal concerns and expectations about drug treatment. This Review summarizes current evidence of the safety of the most common antimigraine medications during pregnancy and breastfeeding, and provides treatment recommendations for use in clinical practice.

Migraine and the risk for stroke and cardiovascular disease

Numerous data have pointed to an association between migraine and cardiovascular diseases. The majority of the available data have indicated that migraine with aura can be considered a risk factor for ischemic stroke, whereas migraine without aura cannot be reliably considered as such. High frequency of attacks and a recent onset of migraine have been related to an increased ischemic stroke risk. In addition, in young subjects with ischemic stroke migraine with aura represents an independent risk factor of overall recurrent vascular events and of recurrent ischemic stroke. Also the risk of transient ischemic attack seems to be increased in migraineurs, although this issue has not been extensively investigated. Several studies have also addressed the possible association between migraine and hemorrhagic stroke. Although the results of these individual studies were conflicting, their meta-analysis showed that migraine is associated with a 1.5-fold increase in the risk of hemorrhagic stroke (including intracerebral and subarachnoid hemorrhage). Some studies have identified migraine also as a possible risk factor for cardiac vascular events while others have yielded negative results. A meta-analysis did not show an increased risk of myocardial infarction in subjects with any migraine vs no migraine but subsequently, data has pointed to an association between any migraine with cardiac ischemic disease. Migraine has also been associated by some studies with vascular mortality and with vascular diseases in regions other than the brain and the heart. Several studies have also indicated that compared with nonmigraineurs, migraineurs have a higher burden of asymptomatic white matter brain lesions and, according to some studies, also infarct-like lesions at brain magnetic resonance. The mechanisms underlying the relationship between migraine and cardiovascular disease are still unclear. The possible explanation may rely on a peculiar vascular vulnerability of migraineurs that may contribute to the pathogenesis of migraine and, in the presence of some other unknown factors may also contribute, over time, to the development of cardiovascular disease. At the moment, there are no reliable features that may indicate which subjects, across the overall migraine population, will develop vascular events and so far, no drugs are recommended for the vascular prevention in migraineurs unless other clear indications are present. In general, the acute treatment and the secondary prevention measures of a patient with stroke who has a history of migraine do not differ from that of other stroke patients. There is currently no direct evidence to support that a migraine prophylactic treatment will reduce future stroke risk in secondary prevention.

Factors Associated with Low Birth Weight of Children Among Employed Mothers in Pakistan

Evidence shows that Pakistan has an increasing rate of children with low birth weight (LBW). Employed mothers in paid work (EMPW) in the country have predominantly been disadvantaged in terms of access to education and low-income employment; with negative consequences on maternal and child health. The objective of this study was to determine socio-demographic characteristics of EMPW and identify the association between maternal employment and child birth weight in Pakistan. Secondary data from the Pakistan Demographic Health Survey (PDHS) conducted for the year 2006-2007 was used. PDHS is a nationally representative household survey. Relevant data needed from the PDHS data file were coded and filtered. The sample size of EMPW with at least one child born in the last 5 years was 2,515. Data was analyzed by using SPSS. Descriptive and inferential statistics were used to see the association between EMPW characteristics and LBW. Findings confirm that the majority of EMPW in Pakistan are illiterate, poor, employed in unskilled work, and belonging to rural regions. Multivariate regression analysis revealed statistical association between EMPW and LBW among mothers who did not receive prenatal care from unskilled healthcare provider (AOR 1.92; 95% CI 1.12-3.30), had lack of access to information such as radio (AOR 1.88; 95% CI 1.28-2.77), during pregnancy did not receive calcium (AOR 1.19; 95% CI 1.05-1.34), and iron (AOR 1.33; 95% CI 1.05-1.69), had experienced headaches during pregnancy (AOR 1.41; 95% CI 1.12-1.76), and were not paid in cash for their work (AOR 1.41; 95% CI 1.04-1.90). EMPW in Pakistan, especially in low-income jobs and rural regions, need urgent support for healthcare awareness, free supplementation of micronutrients and frequent consultation with trained practitioner during the prenatal period. Long-term mobilization of social structure and governance is needed to encourage maternal health awareness, hospital deliveries, and formal sector employment for EMPW.

Markers of endothelial function in migraine patients: Results from a bi-center prospective study

Background

Numerous studies suggest an increased vascular risk in patients with migraine, in particular in those with aura. A possible link between both conditions might be a dysfunction of the vascular endothelium. This observational study analyzed the endothelial markers angiopoietin-1, angiopoietin-2, Tie-2, sFlt-1 and NT-proBNP for the first time in migraineurs, patients with other primary headache disorders and healthy controls.

Methods

Patients with episodic migraine with and without aura, episodic cluster headache, tension-type headache and healthy controls were included. Blood samples were obtained during migraine attacks and headache-free periods in migraineurs, in and out of bout in cluster headache and during headache-free periods in tension-type headache and healthy individuals to analyze markers of endothelial function.

Results

No significant difference in endothelial markers between migraine, other headache disorders and healthy controls was detected. There was no significant difference between migraine attacks and headache-free intervals. Additionally, no distinction could be found between migraine with and without aura.

Discussion

The endothelial markers analyzed do not display a characteristic pattern in different headache disorders especially migraine compared to healthy controls. The novel findings of our study indicate that factors other than endothelial dysfunction seem to be responsible for the at least statistical association of migraine with vascular disease.

Migraine in pregnancy and lactation

Migraine headache is a significant health problem affecting women more than men. In women, the hormonal fluctuations seen during pregnancy and lactation can affect migraine frequency and magnitude. Understanding the evaluation of headache in pregnancy is important, especially given the increased risk of secondary headache conditions. Pregnancy and lactation can complicate treatment options for women with migraine because of the risk of certain medications to the fetus. This review includes details of the workup and then provides treatment options for migraine during pregnancy and lactation.

Migraine, cardiovascular disease, and stroke during pregnancy: Systematic review of the literature

Objective

The objective of this article is to review the literature relating migraine, cardiovascular disease, and stroke during pregnancy in order to better define the relationship between migraines and vascular disease.

Methods

We conducted a systematic review of the literature using Medline and Cochrane Review with the following search terms: migraine AND pregnancy and vascular disease OR myocardial infarction OR heart disease OR stroke OR cerebrovascular disease OR hypertension in pregnancy. We also reviewed the bibliographies of papers identified in this search to obtain additional relevant studies.

Results

Of the 219 papers obtained with the primary search, we found 17 that were topically relevant. Altogether, there is an increased risk both of gestational hypertension (OR range from 1.23 to 1.68) and preeclampsia (OR range 1.08 to 3.5) in migraineurs compared to nonmigraineurs. In addition, there is an association between an increased risk of ischemic stroke in pregnancy (OR range 7.9 to 30.7), particularly with active migraine. There is also an association between migraine and increased risk of acute myocardial infarction and heart disease (OR 4.9; 95% CI 1.7, 14.2), and thromboembolic events during pregnancy (deep venous thrombosis OR 2.4; 95% CI 1.3, 4.2 and pulmonary embolus OR 3.1; 95% CI 1.7, 5.6).

Conclusion

In this review, we summarized the association between migraine and risk of vascular disease during pregnancy, based on the available literature. Given the limited amount of data, more research on these associations is needed to determine which women with migraine may be at risk while pregnant.

Hypertension in pregnancy

Hypertensive disorders of pregnancy represent the second commonest cause of direct maternal death and complicate an estimated 5-10 % of pregnancies. Classification systems aim to separate hypertension similar to that seen outside pregnancy (chronic and gestational hypertension) from the potentially fatal pregnancy-specific conditions. Preeclampsia, HELLP syndrome, and eclampsia represent increasing severities of this disease spectrum. The American College of Obstetricians and Gynecologists' 2013 guidelines no longer require proteinuria as a diagnostic criterion, because of its variable appearance in the disease spectrum. The cause involves inadequate cytotrophoblastic invasion of the myometrium, resulting in placental hypoperfusion and diffuse maternal endothelial dysfunction. Changes in angiogenic and antiangiogentic peptide profiles precede the onset of clinical preeclampsia. Women with preeclampsia should be closely monitored and receive magnesium sulfate intravenously if severe features, HELLP syndrome, or eclampsia occur. Definitive therapy is delivery of the fetus. Hypertension in pregnancy increases future maternal risk of hypertension and cardiovascular disorders.
