Quality of Life in Migraine Patients: A Qualitative Study

Consensus recommendations on the role of nurses in headache care: A European e-Delphi study

BACKGROUND

Nurses work at headache centres throughout Europe, and their care for migraine patients is acknowledged. However, the specific roles and tasks of nursing vary, and a unified understanding is lacking, posing challenges to knowledge sharing and research.

OBJECTIVES

Using an e-Delphi study method, the objective is to obtain healthcare professional headache experts' opinions on nursing-specific roles and tasks and combine this into consensus statements for nurse recommendations for migraine treatment.

METHODS

A three-round questionnaire study was conducted with nurses and neurologists from 18 specialised headache centres in 10 countries. In round 1, statements were compiled from a systematic examination of existing literature and expert opinions. In rounds 2 and 3, the experts rated the importance of statements (from round 1) on a 5-point Likert scale. Statements were analysed using a content analysis method, and the consensus of pre-defined statements was evaluated with gradually increased predetermined criteria using descriptive statistics.

RESULTS

Twenty-one experts, representing all 10 countries, participated. The predetermined consensus of ≥70% agreement was reached for 42 out of the initial 63 statements. These statements formed the final recommendations within two themes: "The nurses' roles and tasks in the clinical setting" and "The nurses' roles and tasks in educating patients and colleagues." The consensus level of statements was strong, with 40% receiving unanimous agreement (100%) and 97% achieving relatively high agreement (>80%).

CONCLUSION

Nursing plays a vital role with diverse tasks in migraine care. This study offers practical recommendations and a framework for nurses, equipping them with a clinical tool to enhance care and promote a coordinated approach to migraine treatment.

MigraineTracker: Examining Patient Experiences with Goal-Directed Self-Tracking for a Chronic Health Condition

Self-tracking and personal informatics offer important potential in chronic condition management, but such potential is often undermined by difficulty in aligning self-tracking tools to an individual's goals. Informed by prior proposals of goal-directed tracking, we designed and developed MigraineTracker, a prototype app that emphasizes explicit expression of goals for migraine-related self-tracking. We then examined migraine patient experiences in a deployment study for an average of 12+ months, including a total of 50 interview sessions with 10 patients working with 3 different clinicians. Patients were able to express multiple types of goals, evolve their goals over time, align tracking to their goals, personalize their tracking, reflect in the context of their goals, and gain insights that enabled understanding, communication, and action. We discuss how these results highlight the importance of accounting for distinct and concurrent goals in personal informatics together with implications for the design of future goal-directed personal informatics tools.

Self-management Experience of Nurses Living with Migraine: A Qualitative Study

BACKGROUND

Migraine is a neurobiological condition characterized by a constellation of unpredictable symptoms and is the second cause of disability worldwide. Migraine is prevalent among nurses. However, literature exploring nurses' experience of living with migraine is scarce which has important individual and systems implications for health and wellness and patient safety. Self-management is essential in chronic disease management as the patient engages in various strategies to be able to live with their condition.

PURPOSE

This study explored the experiences of living and working with migraine among female nurses in Ontario, with particular attention to their priorities and strategies for self-management.

METHODS

Interpretive description methodology was employed to guide this study and informed a thematic analysis approach to examine the self-management experiences of nurses living with migraine.

RESULTS

Nurses engaged in various self-management strategies including pharmacological and non-pharmacological strategies and highlighted the role of technology in migraine self-management. Participants described experiences of living with migraine as an invisible condition including feelings of not being understood, stigmatization, and the absence of formal support at the workplace.

CONCLUSION

The implications of these findings support the incorporation of a critical approach to relational engagement that is person-centred including nonjudgemental, strength-based care as a practice approach when caring for persons living with migraines and the need to include experiential learning in educational curriculums as a strategy to reduce stigma against migraines.

The impacts of migraine on functioning: Results from two qualitative studies of people living with migraine

OBJECTIVE

To describe the impact of migraine on functioning based on comprehensive data collection, analysis, and reporting of patients' experiences.

BACKGROUND

Qualitative research conducted to understand patients' perspectives on living with migraine has often focused on narrow topics or specific groups of patients or has been selectively reported.

METHODS

Qualitative interviews with 71 participants were conducted during two concept elicitation studies as part of the Migraine Clinical Outcome Assessment System (MiCOAS) project, an FDA grant-funded program designed to develop a core set of patient-centered outcome measures for migraine clinical trials. Participants self-reported being diagnosed with migraine by a healthcare professional and participated in semi-structured qualitative interviews about their experiences with the symptoms and impacts of migraine. Interview transcripts were coded to identify and define concepts, which were then grouped into broad domains based on conceptual similarities.

RESULTS

A total of 66 concepts were identified: 12 for physical functioning, 16 for cognitive functioning, 10 for social role functioning, 19 for emotional and psychological functioning, and 9 related to migraine management. Participants described a complex and varied relationship between migraine attack symptoms and impacts on functioning. Impacts from migraine were further influenced by numerous contextual factors, such as people's individual social environments and the level of day-to-day demand for functioning they face.

CONCLUSION

Findings showed that migraine impacted individual functioning in multiple ways and the nature of these impacts was dependent on social-contextual factors. The results are being used in the development of core measures designed to improve our understanding of the burden of migraine and the efficacy of migraine therapies. The results also offer new insights and raise new questions about migraine experience that can be used to guide future research.

Quality of Life in Chinese Youth Following Open Thyroid Surgery: A Qualitative Study

BACKGROUND

Because of the increased incidence of thyroid cancer and good survival rates and with research into scarless techniques, it is increasingly important to understand the quality of life of thyroid cancer patients and identify areas for improvement. Therefore, it is necessary to explore the importance of neck appearance after thyroidectomy for thyroid cancer survivors in China.

OBJECTIVE

The purpose of this study was to investigate the effect of scarring after open thyroid surgery on the quality of life of young patients.

METHODS

A descriptive qualitative design was used. Data were collected using face-to-face semistructured interviews and analyzed using directed content analysis.

RESULTS

Five men and 19 women participated in the study. The following 3 broad themes and 9 subthemes emerged, which were (1) emotional functioning, including low self-esteem due to high visibility of scars, concerns and helplessness about scarring lesions, and feelings of isolation due to lack of support; (2) social functioning, including restricted choice of employment, avoidance of socializing with others, and reduced participation in social activities; and (3) information seeking, acceptance, and living with the scar, including bargaining, seeking professional help, and use of social media.

CONCLUSIONS

After open surgery for thyroid cancer, patients experience a variety of scarring features that affect their quality of life. Therefore, preoperative communication and long-term postoperative care should be emphasized in clinical practice and research.

IMPLICATIONS FOR PRACTICE

Understanding the experience of carrying scars after thyroid cancer surgery helps provide adequate information, expectation management, and informed decision-making.

Rethinking headache as a global public health case model for reaching the SDG 3 HEALTH by 2030

The 2030 Agenda for Sustainable Development sets out, through 17 Sustainable Development Goals (SDGs), a path for the prosperity of people and the planet. SDG 3 in particular aims to ensure healthy lives and promote well-being for all at all ages and includes several targets to enhance health. This review presents a "headache-tailored" perspective on how to achieve SDG 3 by focusing on six specific actions: targeting chronic headaches; reducing the overuse of acute pain-relieving medications; promoting the education of healthcare professionals; granting access to medication in low- and middle-income countries (LMIC); implementing training and educational opportunities for healthcare professionals in low and middle income countries; building a global alliance against headache disorders. Addressing the burden of headache disorders directly impacts on populations' health, as well as on the possibility to improve the productivity of people aged below 50, women in particular. Our analysis pointed out several elements, and included: moving forward from frequency-based parameters to define headache severity; recognizing and managing comorbid diseases and risk factors; implementing a disease management multi-modal management model that incorporates pharmacological and non-pharmacological treatments; early recognizing and managing the overuse of acute pain-relieving medications; promoting undergraduate, postgraduate, and continuing medical education of healthcare professionals with specific training on headache; and promoting a culture that favors the recognition of headaches as diseases with a neurobiological basis, where this is not yet recognized. Making headache care more sustainable is an achievable objective, which will require multi-stakeholder collaborations across all sectors of society, both health-related and not health-related. Robust investments will be needed; however, considering the high prevalence of headache disorders and the associated disability, these investments will surely improve multiple health outcomes and lift development and well-being globally.

Living with migraine: A meta-synthesis of qualitative studies

Introduction

Migraine is one of the top ten causes of disability worldwide. However, migraine is still underrated in society, and the quality of care for this disease is scant. Qualitative research allows for giving voice to people and understanding the impact of their disease through their experience of it. This study aims at synthesising the state of the art of qualitative studies focused on how people with migraine experience their life and pathology.

Methods

MEDLINE via PubMed, EMBASE, CINAHL, PsycINFO, and Cochrane Library were consulted up to November 2021 for qualitative studies. Studies to be eligible had to focus on adults (age > 18 years) with a diagnosis of primary episodic or chronic migraine following the International Classification of Headache. The quality of the study was analysed using the CASP (Critical Appraisal Skills Programme) tool. The synthesis was done through a thematic analysis. CERQual (Confidence in Evidence from Reviews of Qualitative research) approach was used to assess the confidence in retrieved evidence.

Results

Ten studies were included, counting 262 people with migraine. Our synthesis produced four main themes. (1) “Negative impact of migraine symptoms on overall life” as migraine negatively impacts people's whole life. (2) “Impact of migraine on family, work and social relationship” as migraine reduces the possibility to focus at work and interact with people. (3) “Impact of migraine on emotional health” as people with migraine experience psychological distress. (4) “Coping strategies to deal with migraine” such as keep on living one's own life, no matter the symptoms.

Conclusions

Migraine negatively impacts people's whole life, from private to social and work sphere. People with migraine feel stigmatised as others struggle with understanding their condition. Hence, it is necessary to improve awareness among society of this disabling condition, and the quality of care of these people, tackling this disease from a social and health-policy point of view.

Consensus recommendations on the role of nurses in the care of headache patients: protocol for a european e-delphi study

BACKGROUND

Nurses play an important role in the treatment of headache patients at the specialized headache centers in Europe, however, a unified definition of nursing tasks and conduction of tasks is lacking. The objective of this e-Delphi study is twofold. Initially, to obtain healthcare professional headache experts' opinions on which tasks are associated with nurses' care in migraine treatment. Then, through an iterative multi-staged process, to combine the opinions into group consensus statements and develop evident European nursing recommendations for migraine treatment.

METHODS

In Delphi studies there are no unambiguous methodological guidelines and this protocol is being published to ensure transparency and quality in the study process. We invite nurses working in specialized headache centers and neurologists co-working with nurses in Finland, Denmark, Norway, Sweden, United Kingdom, Netherlands, Germany, Ireland, Estonia and Switzerland to participate anonymously in the expert panel. This e-Delphi study consists of three rounds of online questionnaires. We use Open-ended questions to capture the essentials of nurse tasks as understood by the expert panel members. Data are analyzed using content analysis. Predefined statements are applied for the experts to rate the importance of nurses' tasks synthesized from a systematic examination of the existing literature. Consensus is measured using descriptive statistics; median, Interquartile range (IQR) and percentage agreement. Measurement of agreement between participants will be analyzed using inferential statistics; Kendall's coefficient and stability between rounds; Wilcoxon rank-sum test. Statements, which receive consensus in the third round, are included in the final compilation of European recommendations for nurse care for migraine patients.

DISCUSSION

The e-Delphi study will provide European recommendations on nurse care in migraine treatment, which could not be created on the basis of the existing literature. The recommendations can open for the conduction of further research including measurement of efficacy of clinical implementation of the recommended tasks.

TRIAL REGISTRATION

The study is registered at The Region of Southern Denmark (21/52,885). According to The Regional Ethical Committee and Danish law, no additional approval is relevant (20212000-145). A written informed consent is obtained from all participants before inclusion in the study.

A qualitative evidence synthesis of patient perspectives on migraine treatment features and outcomes

OBJECTIVES

We aimed to identify migraine treatment features preferred by patients and treatment outcomes most valued by patients.

BACKGROUND

The values and preferences of people living with migraine are critical for both the choice of acute therapy and management approach of migraine.

METHODS

We conducted a qualitative evidence synthesis. Two reviewers independently selected studies, appraised methodological quality, and undertook a framework synthesis. We developed summary of findings tables following the approach of Grading of Recommendations, Assessment, Development and Evaluations Confidence in the Evidence from Reviews of Qualitative Research to assess confidence in the findings.

RESULTS

Of 1691 candidate references, we included 19 studies (21 publications) involving 459 patients. The studies mostly recruited White women from North America (11 studies) and Europe (8 studies). We identified eight themes encompassing features preferred by patients in a migraine treatment process. Themes described a treatment process that included shared decision-making, a tailored approach, trust in health-care professionals, sharing of knowledge and diversity of treatment options, a holistic approach that does not just address the headache, ease of communication especially for complex treatments, a non-undermining approach, and reciprocity with mutual respect between patient and provider. In terms of the treatment itself, seven themes emerged including patients' preferences for nonpharmacologic treatment, high effectiveness, rapidity of action, long-lasting effect, lower cost and more accessibility, self-management/self-delivery option that increases autonomy, and a mixed preference for abortive versus prophylactic treatments. The treatment outcomes that have high value to patients included maintaining or improving function; avoiding side effects, potential for addiction to medications, and pain reoccurrence; and avoiding non-headache symptoms such as nausea, vomiting, and sensitivity to light or sounds.

CONCLUSION

Patient values and preferences were individually constructed, varied widely, and could be at odds with conventional medical perspectives and evidence of treatment effects. Considering the availability of numerous treatments for acute migraine, it is necessary that decision-making incorporates patient values and preferences identified in qualitative research. The findings of this qualitative synthesis can be used to facilitate an individually tailored approach, strengthen the patient-health-care system relationship, and guide choices and decisions in the context of a clinical encounter or a clinical practice guideline.

Acupuncture for Psychological Disorders Caused by Chronic Pain: A Review and Future Directions

Accumulating evidence supports an association between chronic pain and psychological disorders, a connection that seems to be bidirectional. Treating both the pain and psychological conditions together is essential for effective treatment outcomes. Acupuncture is a somatosensory-guided mind-body therapy that can tackle the multidimensional nature of pain with fewer or no serious adverse effects. In this review, we discuss the use of acupuncture in some conditions with a high incidence of psychological disorders caused by chronic pain: headache, musculoskeletal pain, low back pain, and cancer pain, focusing on the effect and potential mechanisms of acupuncture. Overall clinical studies indicated that acupuncture might effectively contribute to management of psychological disorders caused by chronic pain. Mechanistic studies showed that acupuncture significantly alleviated such psychological disorders by regulating the activity of amygdala and insula, and regulating functional connectivity of insular and limbic regions/medial prefrontal cortex in humans and the corresponding animal models. In addition, 5-HT in the dorsal raphe nucleus, opioid receptors in the cingulate cortex, and plasma met-enkephalin are involved in acupuncture relief of pain and psychological symptoms. Substantial evidences from animal and human research support a beneficial effect of acupuncture in psychological disorders caused by chronic pain.

Access to Migraine Treatments in Ontario, Canada: A Review of the Ontario Drug Benefit Program

BACKGROUND

This paper provides a critical review of the decision-making process of the Ontario Ministry of Health and Long-Term Care (MOHLTC) regarding which migraine treatment drugs will be covered under the Ontario Drug Benefit Formulary (ODB).

MAIN TEXT

Under MOHLTC policy, triptans and OnabotulinumtoxinA are available to patients only through the Exceptional Access Program (EAP). This policy, and justifications for it, are examined with reference to clinical guidelines, patient experiences, and health policy literature. The contexts and consequences of compromised access are outlined. Improvements in access to these treatments are suggested by highlighting how a country with similar healthcare infrastructure - Australia - employs policies that more adequately meet the needs of migraine patients as they secure treatments.

CONCLUSIONS

Despite clinically significant gains in the discovery of safe and effective migraine-specific treatments the ODB thus far has failed to align its practice with current clinical recommendations. This forces patients to rely heavily on medication that, while still effective for some, is potentially suboptimal. This review concludes it is prudent, at minimum, to follow clinical recommendations that advocate for the removal of triptans from EAP and recategorize them as Limited Use drugs. Ideally, moving them to a general benefit would further remove the barriers experienced by patients attempting to access this treatment.

Development and Implementation of the Integrative Toolbox for Headache Management

Patients with migraine are interested in integrative therapies and overall wellness. They also suffer from social isolation as they try to manage a chronic medical condition. We implemented a three-part workshop structured as a group visit that teaches multiple integrative therapies from specialists and offers a chance for shared support and learning.

Content Validity of HIT-6 as a Measure of Headache Impact in People With Migraine: A Narrative Review

Background

The short‐form Headache Impact Test (HIT‐6) is a widely used patient‐reported outcome measure that assesses the negative effects of headaches on normal activity. It was developed using the general headache population and prior to the establishment of the now well‐accepted FDA patient‐reported guidance.

Objective

The objective of this narrative review was to examine existing qualitative research in patients with migraine and headache, providing insight into the relevance and meaningfulness of HIT‐6 items to the lives of migraine patients.

Methods

Articles were identified through database searches (National Library of Medicine and Google Scholar) and review of reference lists of candidate articles.

Results

A total of 3227 articles were identified through database and hand searching. Of these, 12 contained patient‐ or expert‐generated qualitative information regarding headache patients’ experience (8 specific to migraine [episodic and chronic] patients and 4 citing general headache patients). The combined publications described a total of 283 patient interviews. Overarching themes and specific information were identified that provide support of the relevance of content for each HIT‐6 item to migraine patients’ lives. Identified effects of headaches on patients with migraine included limitations in daily activities, needing to lie down during headaches, feeling tired, being irritated by headaches, difficulty concentrating, and the experience of pain. Further, previous research specific to the HIT‐6 indicated that patients understood the instructions, items, and response scales as intended by the instrument authors.

Conclusions

This narrative literature review demonstrates qualitative research support for the relevance of the items of the HIT‐6 in migraine patients, supporting its ongoing use in clinical migraine research and practice.

Treatment patterns and characteristics of patients with migraine in Japan: A retrospective analysis of health insurance claims data

OBJECTIVE

To describe treatment patterns of migraine patients in the Japan Medical Data Center (JMDC) database.

METHODS

Patients aged ≥18 years with ≥1 inpatient or ≥2 outpatient migraine diagnoses, ≥1 outpatient diagnosis and ≥1 migraine-specific acute treatment (triptan or ergotamine), or ≥2 migraine-specific acute treatments from 1 May 2011 to 30 April 2014 were identified. Patients were required to be enrolled in a health plan for ≥1 year before and after the index date. The first migraine diagnosis or acute treatment defined the index date. Patients were stratified by the migraine treatments observed after the index date (i.e. migraine-specific acute treatment only [AT], prophylactic with or without migraine-specific acute treatment [PT], or no treatment [NT]) and described regarding the first migraine treatment regimen and subsequent treatment patterns during up to 1 year of follow-up.

RESULTS

A total of 16,443 patients met the eligibility criteria (9873 AT, 3022 PT, and 3548 NT). AT patients had mean (SD) 10.3 (20.5) acute treatment days during 1-year follow-up, and 81.9% received triptans. When assessing the first migraine treatment regimen during follow-up in PT patients, 29.2% received prophylactic treatment only and 51.7% received both acute and prophylactic treatment. Calcium-channel blockers with or without concomitant triptans (34.4%) were the most common first regimen. Approximately 62.2% discontinued initial prophylactic treatment after an average of 61.2 days (SD = 65.3) of persistent treatment. Among discontinuers, 15.2% reinitiated original treatment and 7.0% switched treatment post-discontinuation within a year, while the remaining patients did not receive prophylactic therapy following discontinuation.

CONCLUSIONS

Among Japanese migraine patients, prophylactic use was low and associated with a high rate of discontinuation following a brief treatment period. Many patients reinitiated or switched treatment following discontinuation, while a significant proportion of patients remained discontinued from prophylactic therapy, suggesting a high unmet need.

Development of an education and self-management intervention for chronic headache - CHESS trial (Chronic Headache Education and Self-management Study)

BACKGROUND

Self-management interventions are well recognised and widely used in chronic conditions. Their application to chronic headaches has been limited and generally of low quality. We describe here our process for developing an evidence based, and theory driven, education and self-management intervention for those living with chronic headache.

METHODS

Our intervention was designed using several core information sources; the results of three systematic reviews, qualitative material from those living with chronic headaches, our knowledge from existing self-management interventions; and finally collaborative input from a multidisciplinary team of clinicians, academics, patients, and charity partners. We manualised the intervention and associated training as a package for use in a feasibility study. We made adaptations for its use in a randomised controlled trial.

RESULTS

We piloted the intervention in four groups with a total of 18 participants. Qualitative feedback from 12 participants and five facilitators allowed the intervention to be refined for the main randomised controlled trial. Some of the key changes included shortening of the overall intervention, changes to the originally planned facilitators and spreading the facilitator training over three days rather than two. We are now testing the final revised intervention in a randomised controlled trial of its clinical and cost effectiveness. The group component of the intervention is delivered over two days with the first day focused on living, understanding and dealing with chronic headaches and the second day exploring how to adapt and take control of one's life with chronic headaches.

CONCLUSION

Our pilot work indicates that our intervention is feasible to deliver, and with the relevant changes would be acceptable for use with this population. Our randomised control trial is ongoing. We anticipate publishing final results in 2021.

Is selective 5-HT1F receptor agonism an entity apart from that of the triptans in antimigraine therapy?

Migraine is a neurovascular disorder that involves activation of the trigeminovascular system and cranial vasodilation mediated by release of calcitonin gene-related peptide (CGRP). The gold standard for acute migraine treatment are the triptans, 5-HT1B/1D/(1F) receptor agonists. Their actions are thought to be mediated through activation of: (i) 5-HT1B receptors in cranial blood vessels with subsequent cranial vasoconstriction; (ii) prejunctional 5-HT1D receptors on trigeminal fibers that inhibit trigeminal CGRP release; and (iii) 5-HT1B/1D/1F receptors in central nervous system involved in (anti)nociceptive modulation. Unfortunately, coronary arteries also express 5-HT1B receptors whose activation would produce coronary vasoconstriction; hence, triptans are contraindicated in patients with cardiovascular disease. In addition, since migraineurs have an increased cardiovascular risk, it is important to develop antimigraine drugs devoid of vascular (side) effects. Ditans, here defined as selective 5-HT1F receptor agonists, were developed on the basis that most of the triptans activate trigeminal 5-HT1F receptors, which may explain part of the triptans' antimigraine action. Amongst the ditans, lasmiditan: (i) fails to constrict human coronary arteries; and (ii) is effective for the acute treatment of migraine in preliminary Phase III clinical trials. Admittedly, the exact site of action is still unknown, but lasmiditan possess a high lipophilicity, which suggests a direct action on the central descending antinociceptive pathways. Furthermore, since 5-HT1F receptors are located on trigeminal fibers, they could modulate CGRP release. This review will be particularly focussed on the similarities and differences between the triptans and the ditans, their proposed sites of action, side effects and their cardiovascular risk profile.

Preventive therapy with citalopram added to a beta blocker does not result in quality-of-life improvement in patients with episodic migraine

Background:

The quality of life of migraine patients, particularly mental domains, is severely diminished despite the preventive therapies available. We aimed to evaluate whether citalopram plus nadolol is superior to nadolol alone in terms of quality of life (QOL) in migraine patients.

Methods:

Adult patients with episodic migraine (≥ 3 headache days per month) were allocated by simple randomization to nadolol 40 mg daily plus citalopram 10 mg daily or to nadolol alone. Baseline visit confirmed the entry criteria and patients filled out a generic QOL (SF-36) as well a migraine-specific questionnaire (MSQoL), a measure of migraine-related disability (MIDAS), a headache calendar and Beck inventory for depression and anxiety. This battery was again completed after 16 weeks of therapy.

Results:

A total of 92 patients from a general neurology clinic completed the study, 85% females with migraine without aura. Fourty-four (47.83%) patients were allocated to nadolol therapy, and 48 (52.17%) to the combination of nadolol plus citalopram. After therapy, both groups had a similar gain in quality of life (SF-36 and MSQOL), but combination therapy was not superior to nadolol. Despite this improvement, all SF-36 domains remained below the population norms in both groups.

Conclusion:

Adding systematically citalopram 10 mg daily to a conventional migraine preventive drug (nadolol) does not result in an additional improvement in the QOL of migraine patients.

The lived experience of chronic headache: a systematic review and synthesis of the qualitative literature

OBJECTIVE

To systematically review the qualitative literature of the lived experience of people with a chronic headache disorder.

BACKGROUND

Chronic headaches affect 3%-4% of the population. The most common chronic headache disorders are chronic migraine, chronic tension-type headache and medication overuse headache. We present a systematic review and meta-ethnographic synthesis of the lived experience of people with chronic headache.

METHODS

We searched seven electronic databases, hand-searched nine journals and used a modified Critical Appraisal Skills Programme checklist to appraise study quality. Following thematic analysis we synthesised the data using a meta-ethnographic approach.

RESULTS

We identified 3586 unique citations; full texts were examined for 86 studies and 4 were included in the review. Included studies differed in their foci: exploring, patient-centred outcomes, chronic headache as a socially invisible disease, psychological processes mediating impaired quality of life, and the process of medication overuse. Initial thematic analysis and subsequent synthesis gave three overarching themes: 'headache as a driver of behaviour' (directly and indirectly), 'the spectre of headache' and 'strained relationships'.

CONCLUSION

This meta-synthesis of published qualitative evidence demonstrates that chronic headaches have a profound effect on people's lives, showing similarities with other pain conditions. There were insufficient data to explore the similarities and differences between different chronic headache disorders.

The effect of melatonin on gene expression of calcitonin gene-related peptide and some proinflammatory mediators in patients with pure menstrual migraine

The neuropeptide calcitonin gene-related peptide (CGRP), a potent vasoactive and a marker of trigeminal inflammation, has been considered as an important mediator in various types of migraine such as pure menstrual migraine. Earlier studies have shown that CGRP can modulate the synthesis and release of other inflammatory factor including nitric oxide (NO) and interleukin-1beta (IL-1β) from trigeminal ganglion glial cells. Exogenous melatonin protects the tissues from inflammatory damages. The goal of this study was to determine the anti-inflammatory effects of melatonin on the CGRP expression, inducible nitric oxide synthase (iNOS) activity, NO, and IL-1β release in cultured peripheral blood mononuclear cells (PBMCs) from pure menstrual migraine patients and healthy subjects. This study was performed on 12 pure menstrual migraine patients and 12 age-and sex-matched healthy subjects. PBMCs were isolated and treated with melatonin for 12 h at pharmacological dose. Gene expression was evaluated by real-time PCR. CGRP and IL-1β proteins in culture supernatant were determined by ELISA method. iNOS activity in PBMCs was determined by colorimetric assays. Total nitrite as an indicator of NO concentrations in the culture supernatants was measured using Griess method. We found that melatonin treatment significantly decreases mRNA expression of CGRP release, NO production, and iNOS activity in the patient groups. Taken together, it appears that melatonin reduces inflammation through decreasing CGRP level and iNOS activity in the patients with migraine; however, further studies are needed in this regard.

Living with chronic migraine: a qualitative study on female patients' perspectives from a specialised headache clinic in Spain

OBJECTIVES

The aim of this study was to explore the views and experiences of a group of Spanish women suffering from chronic migraine (CM).

SETTING

Headache clinic at a university hospital in Madrid (Spain).

PARTICIPANTS

Purposeful sampling of patients that attended a specialised headache clinic for the first time between June 2016 and February 2017 was performed. The patients included were females aged 18-65 and with positive diagnoses of CM according to the International Classification of Headache disorders (third edition, beta version), with or without medication overuse. Accordingly, 20 patients participated in the study with a mean age of 38.65 years (SD 13.85).

DESIGN

Qualitative phenomenological study.

METHODS

Data were collected through in-depth interviews, researchers' field notes and patients' drawings. A thematic analysis was performed following appropriate guidelines for qualitative research.

RESULTS

Five main themes describing the significance of suffering emerged: (a) the shame of suffering from an invisible condition; (b) treatment: between need, scepticism and fear; (c) looking for physicians' support and sincerity and fighting misconceptions; (d) limiting the impact on daily life through self-control; and (e) family and work: between understanding and disbelief. The disease is experienced as an invisible process, and the journey to diagnosis can be a long and tortuous one. Drug prescription by the physician is greeted with distrust and scepticism. Patients expect sincerity, support and the involvement of their doctors in relation to their disease. Pain becomes the main focus of the patient's life, and it requires considerable self-control. The disease has a strong impact in the work and family environment, where the patient may feel misunderstood.

CONCLUSIONS

Qualitative research offers insight into the way patients with CM experience their disease and it may be helpful in establishing a more fruitful relationship with these patients.

Rumination in migraine: Mediating effects of brooding and reflection between migraine and psychological distress

OBJECTIVE

The relationship between migraine and psychological distress has been consistently reported in cross-sectional and longitudinal studies. We hypothesised that a stable tendency to perseverative thoughts such as rumination would mediate the relationship between migraine and psychological distress. Design and Main Outcomes Measures: Self-report questionnaires measuring depressive rumination, current psychological distress and migraine symptoms in two independent European population cohorts, recruited from Budapest (N = 1139) and Manchester (N = 2004), were used. Structural regression analysis within structural equation modelling was applied to test the mediational role of brooding and reflection, the components of rumination, between migraine and psychological distress. Sex, age and lifetime depression were controlled for in the analysis.

RESULTS

Migraine predicted higher brooding and reflection scores, and brooding proved to be a mediator between migraine and psychological distress in both samples, while reflection mediated the relationship significantly only in the Budapest sample.

CONCLUSIONS

Elevated psychological distress in migraine is partially attributed to ruminative response style. Further studies are needed to expand our findings to clinical samples and to examine how rumination links to the adjustment to migraine.

Patients' experiences of a behavioural intervention for migraine headache: a qualitative study

BACKGROUND

Migraine headache has a high prevalence and a severe impact on personal, social and work life, forming a significant burden on patients, service providers and society. There is some evidence of the effectiveness of behavioural interventions to supplement drug therapy but a recognised need to identify an effective minimal contact approach to enhance access and provide a model for use in publicly funded health systems. This study uses in-depth interviews to examine patients' experience and responses to a behavioural intervention with relaxation and CBT components delivered in three individual therapist sessions with follow-up.

METHODS

Qualitative study of 20 adults aged 18-75 years in London, UK, with clinically diagnosed migraine and at least four headache days per month. Semi-structured and tape recorded interviews were held post intervention based on a topic guide. Transcripts were coded and charted for all participants and analysed thematically.

RESULTS

The majority of participants cited the impacts of migraine and a desire for additional non-drug treatment as their main reasons for taking part and almost all completed the course. They valued contact with the therapist and almost all reported benefiting from the therapy. Post intervention they used those techniques they found most beneficial and implemented them flexibly in their daily life to reduce stress and risks of migraine or to respond to migraine. Relaxation training (deep breathing) was easily adopted and often used post intervention. The CBT components were mainly viewed positively but regarded as more challenging to learn and implement.

CONCLUSIONS

Patients' selectively identified and employed the techniques learned as 'tools' to assist in preventing and managing their migraines, with reported benefits supporting the development of minimal contact behavioural therapy to increase accessibility for adults with migraine headache and the conduct of a definitive trial.

A pilot study of cognitive behavioural therapy and relaxation for migraine headache: a randomised controlled trial

Headache is being viewed more commonly in a biopsychosocial framework, which introduces the possible utilisation of psychological treatment options, such as cognitive behavioural therapy and relaxation. No such treatments have been trialled in the UK. We conducted a randomised controlled pilot trial, comparing a brief guided self-help CBT and relaxation treatment with standard medical care (SMC), in a UK NHS setting. Participants were recruited from specialist headache clinics across London. Participants were randomised to receive either treatment or standard medical care. Our objective was to provide design information necessary for a future definitive trial of the SHE treatment, including, recruitment/retention rates, acceptability of randomisation, treatment fidelity and estimations of mean and variances of outcome measures. From the initial 275 patients identified, 73 were randomised. There was no difference in drop-out rates between SMC and treatment groups. Of the 36 participants randomised to receive treatment, 72 % attended all sessions. Findings show that a future definitive trial of the SHE treatment is feasible, with small modifications of protocol, within a UK NHS context.

Quality of life in primary headache disorders: A review

BACKGROUND

Health-related quality of life (HRQoL) is emerging as an important element of clinical research in primary headache disorders, allowing a measure of the impact of headache on patients' well-being and daily life. A better understanding of this may contribute to improved resource allocations and treatment approaches.

OBJECTIVE

The objective of this study is to review available data on HRQoL in primary headache disorders and identify any influencing factors.

METHODS

Database searches including MEDLINE, PsycINFO and EMBASE were performed. Studies that investigated HRQoL in patients with primary headache disorders were included and reviewed. Trials that evaluated the efficacy of medications or interventions were excluded.

RESULTS

A total of 80 articles were included in the review. Both physical and emotional/mental aspects of HRQoL were impaired across headache subtypes, although the extent varied depending on headache type. A number of factors influencing HRQoL were also identified.

CONCLUSION

This narrative review suggests that headache, particularly in its chronic form, has a great impact on HRQoL. Clinical practice should not solely focus on pain alleviation but rather adopt routine assessment of HRQoL. Furthermore, identification and management of associated psychological comorbidities, which can significantly influence HRQoL in headache sufferers, are essential for optimal clinical management.

Validation of a survey tool assessing effectiveness of an educational intervention on the caring behaviors and referral activities of community pharmacists for migraineurs

BACKGROUND

Community pharmacists are in an ideal position to ameliorate migraineur under-consulting, under-diagnosis, and under-treatment. Contemporary education/training on developing therapeutic alliances with patients and in advanced pharmacotherapy may further motivate pharmacists to impact the care of migraineurs.

OBJECTIVES

The objectives of this study were to assess pharmacists' perceptions of a migraine training program and their self-assessment of subsequent impact on patient care and to develop and assess a tool evaluating the impact of the training program from the patients' perspectives: (1) for patients diagnosed with migraines - identify perceptions of care by pharmacists who have undergone specialty training in migraine vs. pharmacists who have not; and (2) for patients with recurrent headaches and not diagnosed with migraines - identify perceptions of pharmacist effectiveness and thoroughness, after specialty training, to identify a potential migraine diagnosis and referral for advanced care vs. pharmacists that have not undergone specialty training.

METHODS

This study employed a mixed method survey design using community pharmacies from the Tulsa, Oklahoma and Pittsburgh, Pennsylvania greater metropolitan areas. Pharmacists from intervention pharmacies received specialty training on migraine and were surveyed on their current practices and about the education program. Approximately 1 month after the training, control and intervention pharmacists were surveyed on current practices. Additionally, patients from both pharmacies were surveyed to assess Migraine Disability Assessment (MIDAS) and pharmacists' delivery of care derived from the Pharmacists' Care of Migraineurs Scale (PCMS). Surveys were handed out for a period of 3-months.

RESULTS

There were 16 pharmacists and 61 patients recruited. There was no difference in patient perceptions of pharmacists' care or in patient self-perceptions between migraineurs and recurrent headache sufferers. Ninety-two percent of pharmacists agreed that the program could be transferred to an internet-based educational program. The 14-item patient survey, however, demonstrated good internal consistency reliability, with each question having a Cronbach's alpha 0.80 or higher.

CONCLUSIONS

There are few studies evaluating the role and potential impact community pharmacists can have on patients suffering from migraines or recurrent headaches. While no difference was found between the groups, the internal reliability of the survey questions and the need to address needs of migraineurs warrants tool dissemination and a larger-scale study.

Psychiatric symptoms may contribute to poor quality of life in adolescents with migraine

BACKGROUND

The impact of migraine on quality of life (QOL) can be aggravated by other comorbid factors. The aim of the present study was to assess the differences in the QOL of adolescents with chronic migraine, episodic migraine, and healthy adolescents, and whether the differences in QOL among the diagnostic groups were associated with the presence of self-reported psychiatric symptoms, such as depression and anxiety.

METHODS

A total of 157 adolescents (aged 15-19 years old) were included in the study. Fifty patients had episodic migraine, 56 patients suffered from chronic migraine, and 51 healthy adolescents were controls. All of the participants responded to a detailed headache questionnaire, the Medical Outcomes Trust 36-Item Short-form Health Survey, the State-Trait Anxiety Inventory and the Beck Depression Inventory.

RESULTS

Chronic migraine patients showed a significantly lower QOL than the control subjects in five dimensions of the Medical Outcomes Trust 36-Item Short-form Health Survey, and lower QOL than the episodic migraine patients in four dimensions. High levels of self-reported depressive symptoms were associated with lower QOL in five dimensions and high levels of self-reported anxiety were associated with lower QOL in four dimensions.

CONCLUSIONS

The QOL of adolescent migraine sufferers may be aggravated not only by migraine but also by other factors, such as anxiety and depressive symptoms, which may contribute to the poor QOL in adolescents suffering from migraine.

Overattachment and perceived disability in chronic migraineurs

OBJECTIVES

The aim of this cross-sectional study was to assess whether stagnation dimensions and depression were associated with perceived disability in chronic migraineurs.

METHODS

Participants were 69 consecutive adult outpatients admitted to the Regional Referral Headache Centre of the Sant'Andrea Hospital in Rome, Italy. Patients were administered the Center for Epidemiologic Studies Depression Scale, the Stagnation Scale, and the Italian Perceived Disability Scale. They also compiled a headache diary to compute headache frequency.

RESULTS

Patients with higher perceived disability (compared to patients with lower perceived disability) reported higher depression and higher symptoms of stagnation. The effect of Overattachment, a dimension of the Stagnation Scale, on perceived disability was only in part mediated by the severity of depressive symptoms.

CONCLUSION

Our results confirm that many patients with chronic migraine report symptoms of stagnation, and that investigating the presence of the stagnation syndrome may be useful for understanding the psychology of chronic migraineurs.

Results of a 2-year retrospective cohort study of newly prescribed triptan users in European nationwide practice databases

Objective: This study was conducted to characterize prescription refill patterns for triptans among European patients with new prescriptions of triptans.

Background: Persistency with prescriptions of triptan monotherapy for migraine headache among newly prescribed users in European primary-care practices has not been well described.

Methods: Using electronic medical databases in the UK ( N = 3618), France ( N = 2051) and Germany ( N = 954), we conducted a retrospective cohort analysis to identify refill patterns over 2 years among migraineurs receiving new prescriptions of triptan monotherapy in 2006.

Results: Of all patients, >33% of migraineurs with new triptan prescriptions received ≥1 refill of their index triptan prescriptions (UK, 44.3%; France, 34.2%; Germany, 37.7%). More than 50% never received index-triptan refill prescriptions (UK, 55.7%; France, 65.8%; Germany, 63.3%). Small proportions of patients (<7.0%) switched to alternative triptans, and even fewer switched to different prescription-medication classes (UK and Germany, 2.3%; France, 4.0%). More than 48% of patients received no further prescriptions for migraine after index prescriptions (UK, 48.5%; France, 54.9%; Germany, 54.7%). After the second year, >83.0% of patients in each country had no further prescriptions for migraine medications, <14.0% remained persistent with index prescriptions, <4.0% switched to other triptans, and <3.0% switched to alternative medication classes.

Conclusions: In migraine patients who received new prescriptions of triptan monotherapy from their primary-care physicians, poor triptan prescription refill frequency was observed in Europe. Although consistent with potential clinical challenges in migraine management, our findings should be interpreted with caution given certain inherent limitations associated with the database study design. Further research is warranted to confirm our findings and to identify reasons for, or predictors of, triptan discontinuation.

Prophylactic treatment of migraine by GPs: a qualitative study

BACKGROUND

Despite the considerable impact of migraine, the use of preventive medication in primary care is limited. Only about 5% of migraine patients who qualify for prophylaxis actually receive it, and adherence is far from optimal.

AIM

To explore the opinions of GPs regarding preventive medication for migraine.

DESIGN AND SETTING

A qualitative focus group study in Dutch general practice.

METHOD

Four focus groups (six GPs each) were formed. GPs were purposively sampled to acquire a range of participants, reflecting the more general GP population.

RESULTS

GPs perceived patients' concerns about the impact of migraine and the potential benefits of prophylaxis. However, some were hesitant to start prescribing prophylaxis due to doubts about effectiveness, potential side effects, and the risk of developing drug dependency. GPs' decisions were often based on considerations other than those presented in national guidelines, for example, the patient's need to control their own problem. Many GPs placed responsibility for initiating prophylaxis with the patient.

CONCLUSION

Various considerations hamper GPs from managing migraine with preventive medication, and various patient-related concerns cause GPs to deviate from national headache guidelines.

Prophylactic treatment of migraine; the patient's view, a qualitative study

Background

Prophylactic treatment is an important but under-utilised option for the management of migraine. Patients and physicians appear to have reservations about initiating this treatment option. This paper explores the opinions, motives and expectations of patients regarding prophylactic migraine therapy.

Methods

A qualitative focus group study in general practice in the Netherlands with twenty patients recruited from urban and rural general practices. Three focus group meetings were held with 6-7 migraine patients per group (2 female and 1 male group). All participants were migraine patients according to the IHS (International Headache Society); 9 had experience with prophylactic medication. The focus group meetings were analysed using a general thematic analysis.

Results

For patients several distinguished factors count when making a decision on prophylactic treatment. The decision of a patient on prophylactic medication is depending on experience and perspectives, grouped into five categories, namely the context of being active or passive in taking the initiative to start prophylaxis; assessing the advantages and disadvantages of prophylaxis; satisfaction with current migraine treatment; the relationship with the physician and the feeling to be heard; and previous steps taken to prevent migraine.

Conclusion

In addition to the functional impact of migraine, the decision to start prophylaxis is based on a complex of considerations from the patient's perspective (e.g. perceived burden of migraine, expected benefits or disadvantages, interaction with relatives, colleagues and physician). Therefore, when advising migraine patients about prophylaxis, their opinions should be taken into account. Patients need to be open to advice and information and intervention have to be offered at an appropriate moment in the course of migraine.

Migraine--more than a headache: women's experiences of living with migraine

PURPOSE

In this qualitative study the aim was to explore the meaning of living with migraine.

METHODS

In-depth interviews were conducted with ten women about their experience of living with migraine. Halfway through the interview, the women drew a picture of what living with migraine is like, and the interview continued with the conversation being guided by the picture. The interviews were analyzed using a hermeneutic phenomenological method inspired by van Manen.

RESULTS

The analysis revealed an essence "Being obliged to endure a life accompanied by an unpredictable and invisible disorder" and three themes "Being besieged by an attack", "Struggling in a life characterized by uncertainty" and "Living with an invisible disorder."

CONCLUSIONS

Migraine is a debilitating disorder which accompanies life in the sense that it or the threat of its return is always present, and yet invisible to others. The struggle of enduring life with migraine is worsened by the feeling of having an invisible disorder and of being doubted. There is a need to increase the knowledge among healthcare professionals about what it means to live with migraine, something this qualitative study offers.

Estudo do impacto da enxaqueca na severidade da dor miofascial da musculatura mastigatória

OBJETIVO: comparar a severidade da dor subjetiva e objetiva, além de outras características associadas entre pacientes com dor miofascial com e sem o diagnóstico adicional de enxaqueca. MÉTODOS: foram selecionados 203 pacientes, com idade média de 40,3 anos (89,2% do sexo feminino), que se apresentaram à Clínica de Dor Orofacial da Universidade da Califórnia, Los Angeles, EUA - todos com diagnóstico primário de dor miofascial. Pacientes com diagnóstico secundário de enxaqueca foram incluídos (n=83) e formaram o grupo 2. O teste de Mann-Whitney foi utilizado para comparar o grupo 1 (dor miofascial) com o 2 (dor miofascial + enxaqueca) quanto à intensidade de dor à palpação e subjetiva, através de Escalas Analógicas Visuais (EAV). Também com o auxílio de EAV, foram comparados estado de humor, problemas com a função, qualidade do sono e incapacidade. Em todos os testes foi adotado um nível de significância de 5%. RESULTADOS: o grupo 2 apresentou níveis de dor à palpação muscular estatisticamente maiores que o grupo 1 (p<0,05). Ao se analisar a intensidade de dor subjetiva obtida através da EAV, o grupo 2 apresentou níveis maiores de dor subjetiva (EAV) em todas as medições, com significância estatística para "dor no momento" e "dor máxima" (p<0,05). Da mesma maneira, o grupo 2 mostrou níveis maiores, obtidos através da EAV, de problemas com humor, incapacidade, problemas com a função mandibular e problemas com sono/descanso, sendo que apenas o último apresentou significância estatística (p<0,05). CONCLUSÕES: a comorbidade enxaqueca exerce forte impacto na severidade da dor e na qualidade de vida de pacientes que apresentam diagnóstico primário de dor miofascial.

Migraineurs' perceptions of and interactions with pharmacists: a qualitative study

Aims and objectives

Migraine is an underdiagnosed and undertreated condition. Diagnosed and undiagnosed migraineurs come into frequent contact with pharmacists, who are in a unique position to intervene and potentially improve the therapeutic outcomes of migraineurs; however, little is known about migraineurs' attitudes towards pharmacists' roles and the experiences they have shared with pharmacists. The purpose of this study was to evaluate migraineurs' perceptions of the roles that pharmacists may play in helping them manage their disease.

Setting

Duquesne University, Pittsburgh, Pennsylvania, USA.

Method

The study employed the use of two focus groups of migraineurs from a university population, approached from a phenomenologic perspective. Focus-group sessions were conducted using a flexible interview guide. Focus-group content was digitally recorded, then transcribed, verified for accuracy and content analysed according to established criteria, employing the use of a formal coding procedure. Inductive analysis was performed to establish patterns, themes and categories in the data.

Key findings

Six principal themes emerged. Among the most important findings were that (1) migraineurs were concerned about managing their headaches and the impact migraine has on their lives and their families' lives, (2) migraineurs did not discuss their headaches or migraine therapy with pharmacists and (3) migraineurs believe that many communication barriers exist in their pharmacistpatient relationship.

Conclusion

Community pharmacists have an opportunity to impact the level of care provided to migraine sufferers. As such, community pharmacists should strive to remove communication barriers and be more proactive during interactions with these patients. Further study may examine how pharmacists can elicit more social support for migraineurs and to help migraineurs cope with their condition.

Population-based study of migraine in Spanish adults: relation to socio-demographic factors, lifestyle and co-morbidity with other conditions

The aim of this study was to estimate the prevalence of migraine in the general Spanish population and its association with socio-demographic and lifestyle factors, self-reported health status, and co-morbidity with other conditions. We analyzed data obtained from adults aged 16 years or older (n = 29,478) who participated in the 2006 Spanish National Health Survey (SNHS), an ongoing, home-based personal interview which examines a nation-wide representative sample of civilian non-institutionalized population residing in main family dwellings (household) of Spain. We analyzed socio-demographic characteristics (gender, age, marital status, educational level, occupational status, and monetary monthly income); self-perceived health status; lifestyle habits (smoking habit, alcohol consumption, sleep habit, physical exercise, and obesity); and presence of other concomitant diseases. The 1-year prevalence of diagnosed migraine (n = 3,433) was 11.02% (95% CI 10.55–11.51). The prevalence was significantly higher among female (15.94%) than male (5.91%) and showed the highest value in the 31–50 years age group (12.11%). Migraine was more common in those of lower income (AOR 1.19, 95% CI 1.01–1.41) and who sleep <8 h/day (AOR 1.18, 95% CI 1.04–1.33). Furthermore, worse health status (AOR 2.04, 95% CI 1.76–2.36) and depression (AOR 1.82 95% CI 1.58–2.11) were related to migraine. Finally, subjects with migraine were significantly more likely to have comorbid conditions, particularly chronic (more than 6 month of duration) neck pain (AOR 2.31, 95% CI 1.98–2.68) and asthma (AOR 1.62, 95% 1.27–2.05). The current Spanish population-based survey has shown that migraine is more frequent in female, between 31 and 50 years and associated to a lower income, poor sleeping, worse health status, depression and several comorbid conditions, particularly chronic neck pain and asthma.

Development and construct validation of the pharmacists' care of migraineurs scale

OBJECTIVES

To develop the pharmacists' care of migraineurs scale (PCMS) and to evaluate its psychometric properties.

BACKGROUND

Migraine is often managed suboptimally in primary care. Migraineurs frequently come into contact with community pharmacists, who have the opportunity to make a positive impact on migraineur treatment outcomes. A valid and reliable tool that measures and documents the care provided by pharmacists to migraineurs is critical to the development and evaluation of educational programs and interventions.

METHODS

Relevant domains of pharmacist care and their respective composite items (behaviors) were identified through an extensive literature search and the use of 2 pharmacist and 2 migraineur focus groups sessions. The resultant 45 PCMS items composed a survey questionnaire mailed to a nationwide random sample of 6000 pharmacists. Data were subjected to an exploratory principal axis factoring procedure to discern the factor structure, and as such describe the latent domains composing the pharmacist caring behaviors constructs.

RESULTS

A total of 580 usable responses were returned, with an additional 60 returned as undeliverable, thus yielding a response rate of 9.7%. Exploratory factor analysis using principal axis factoring yielded 9 factors. However, upon examining the scree plot, communalities, and factor loadings, a reanalysis forcing a 7-factor solution yielded a more interpretable and plausible factor structure. The 7-factor solution included the following domains: (1) empathy; (2) prospective drug utilization review for newly diagnosed migraineurs; (3) medication counseling; (4) nonpharmacologic treatment plan; (5) headache sufferer triage; (6) dissemination of public health information; (7) maintenance of knowledge on migraine. Following the application of scale purification procedures, the final instrument is composed of 41 items and demonstrated a Cronbach's alpha reliability of 0.947. Cronbach's alpha reliabilities for the 7 domains ranged from 0.67 to 0.91, indicative of good to excellent internal consistency reliabilities for all the domains.

CONCLUSIONS

The PCMS demonstrated very good construct validity and reliability. While additional validity testing is warranted, the PCMS should allow for benchmarking in the evaluation of interventions designed to improve pharmacists' care to migraineurs and for identifying correlates to effective community pharmacist migraineur care.

Locus of control moderates the relationship between headache pain and depression

The aim of the current study was to triangulate qualitative and quantitative data in order to examine in greater detail the relationship between self-reported headache pain severity, depression and coping styles. Psychosocial scales, headache characteristic scales and in-depth interviews were administered to 71 adults with the diagnosis of primary headache. Regression analyses with the scales showed that greater self-reported headache pain severity was associated with higher levels of depression. A high internal locus of control weakened the relationship between the headache severity and depression variables. The qualitative data supported the relationship between pain severity and internal locus of control and, in addition, revealed that perceived efficacy of pharmacologic intervention might be a related factor. The results suggested that stronger coping skills might reduce depression among headache sufferers.

Physical and mental comorbidity of headache in a nationally representative sample of US adults

OBJECTIVE

To investigate the contribution of comorbidity to health utilization and negative health perception in a large-scale population-based study. Comorbidity of headache with physical and mental disorders has been reported frequently in clinical samples.

METHODS

This concern was addressed using combined 6-year data from the 1999 to 2004 National Health Examination and Nutrition Survey (n = 31,126 adults), nationally representative datasets of the US population. Measures of physical disorders were based on standardized interviews of chronic conditions, and mental disorders were assessed by the Composite International Diagnostic Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition.

RESULTS

The 3-month prevalence of severe headaches or migraine in the US general population was 22.73%, with females and young adults having greater rates than males and older adults. Adults with headache had increased odds for a variety of physical disorders (including asthma, rheumatoid arthritis, and stroke) and mental disorders (including depression, generalized anxiety disorder, and panic disorder). Adults with headache were more likely to rate their health as "fair or poor" (17.9% versus 6.1%), to seek health care four or more times in a year (43.3% versus 22.7%), and to endorse physical and mental limitations. Health utilization and negative health perception were more strongly influenced by comorbid mental disorders than physical disorders.

CONCLUSIONS

The results from this nationally representative sample provide new information on the interrelationships of headache with mental and physical disorders. The greater impact of comorbid mental compared with physical disorders on healthcare utilization and health perception has important implications for the clinical evaluation and treatment of headache in the population.

The passing dilemma in socially invisible diseases: Narratives on chronic headache

This contribution concerns the experience of chronic diseases and how it disrupts the trajectory of a person's biography, undermining his/her identity, self-reliance and social relationships. The study focuses particular attention on those diseases which have not yet been fully acknowledged and can, therefore, be considered a socially invisible disease: chronic headache is one of these. Thirty-one life stories were collected from patients attending a specialized headache centre in Northern Italy, and selected in order to include all common varieties of chronic headache. Following the principles of grounded theory, interviews began by adopting a minimal theoretical framework which consisted of asking people how they became aware of the objective (disease), subjective (illness) and social (sickness) aspects of their condition. The analysis highlighted particular points in the patients' life trajectories: first, the biographical disruption that takes place because of the disease; second, how people succeed or fail in identity negotiation, which is vital for developing an acceptable social representation of the disease. Results show that patient's choices follow a vicious circle, where a partial social representation of the disease is produced. People who suffer from chronic headache face a dilemma in social relationships: should they conceal their disease, or make it evident? If they conceal, any possible social representation of the disease is denied, which could lead to carrying the burden of the disease alone, with no social support. On the other hand, making chronic headache visible could result in stigma.

Impact of preventive therapy with nadolol and topiramate on the quality of life of migraine patients

Preventive therapy is aimed at reducing migraine frequency, but should also improve the much deteriorated quality of life of the migraneur. We aimed to evaluate the impact of preventive therapy with two widely employed drugs (topiramate and nadolol) on the quality of life of migraine patients. A population of consecutive migraineurs aged > or = 16 years, with frequent migraines, was selected prospectively for evaluation at baseline and after 16 weeks of therapy with nadolol or topiramate (40 mg and 100 mg daily, respectively) by generic and specific quality of life questionnaires (SF-36 and MSQOL) and by an anxiety and depression scale (HADS). Preventive therapy resulted in a statistically significant improvement in physical domains of the SF-36, whereas mental domains remained almost unchanged. Despite this improvement, all domains remained below the population norms. The HADS revealed a moderate depressive state at baseline that did not change with therapy. The MSQOL global score also revealed statistically significant improvement. Both drugs were similarly effective, although topiramate was superior on the role physical domain compared with nadolol. Preventive therapy with nadolol and topiramate significantly improves the quality of life of migraineurs, although additional efforts are needed to place them in a nearer-to-normal situation compared with the general population.

Potential role of female sex hormones in the pathophysiology of migraine

Clinical evidence indicates that female sex steroids may contribute to the high prevalence of migraine in women, as well as changes in the frequency or severity of migraine attacks that are in tandem with various reproductive milestones in women's life. While female sex steroids do not seem to be involved in the pathogenesis of migraine per se, they may modulate several mediators and/or receptor systems via both genomic and non-genomic mechanisms; these actions may be perpetuated at the central nervous system, as well as at the peripheral (neuro)vascular level. For example, female sex steroids have been shown to enhance: (i) neuronal excitability by elevating Ca(2+) and decreasing Mg(2+) concentrations, an action that may occur with other mechanisms triggering migraine; (ii) the synthesis and release of nitric oxide (NO) and neuropeptides, such as calcitonin gene-related peptide CGRP, a mechanism that reinforces vasodilatation and activates trigeminal sensory afferents with a subsequent stimulation of pain centres; and (iii) the function of receptors mediating vasodilatation, while the responses of receptors inducing vasoconstriction are attenuated. The serotonergic, adrenergic and gamma-aminobutyric acid (GABA)-ergic systems are also modulated by sex steroids, albeit to a varying degree and with potentially contrasting effects on migraine outcome. Taken together, female sex steroids seem to be involved in an array of components implicated in migraine pathogenesis. Future studies will further delineate the extent and the clinical relevance of each of these mechanisms, and will thus expand the knowledge on the femininity of migraine.

The experiences of midlife women with migraines

PURPOSE

To describe the experiences of midlife women with migraines.

DESIGN AND METHODS

Qualitative data were collected in two consecutive studies, using open-ended interviews, focus groups, and online discussion boards. Interpretive methods were used for analysis.

FINDINGS

Three patterns were identified: Changing Headache Patterns; Predicting, Preventing, and Controlling Headaches; and Keeping on the Move. These patterns indicated how women's headaches changed over time, how headaches were envisioned within the context of their lives, what strategies were used to meet work and home responsibilities, and how women controlled their headaches while maintaining a sense of perspective.

CONCLUSIONS

Many midlife women with migraines receive inadequate or inappropriate treatment, and better dissemination of current diagnostic and treatment guidelines is necessary. Ongoing research is needed to increase understanding of how this problem affects midlife women's lives and of what interventions might prevent or alleviate migraine discomfort.

Gendering the migraine market: Do representations of illness matter?

Migraine is a common, debilitating and costly disorder. Yet help-seeking for and rates of diagnosis of migraine are low. Drawing on ethnographic observations of pharmaceutical marketing practices at professional headache conferences and a content analysis of migraine advertising, principally in the USA, this paper demonstrates: (1) that the pharmaceutical industry directs its marketing of migraine medication to women; and (2) as part of this strategy, pharmaceutical advertisements portray women as the prototypical migraine sufferer, through representations that elicit hegemonic femininity. This strategy creates the impression that migraine is a "women's disorder", which, in turn, exacerbates gender bias in help seeking and diagnosis of migraine and reifies presumptions about the epidemiology of the disorder. I conclude that these pharmaceutical marketing practices have a paradoxical effect: even as they educate and raise awareness about migraine, they also create barriers to help seeking and diagnosis.
