    Abstract Background: Neck pain is common among individuals with migraine, but there is a lack of information of how this comorbidity can be associated with cervical muscle function. This controlled cross-sectional study aimed to compare cervical muscle function, activity, and sensitization in women with migraine, neck pain, both, and neither.
    Methods: This study included women, between 18 and 55 years old, with either episodic migraine with or without aura, without any concomitant headache diagnosis; chronic neck pain, with at least moderate intensity and mild disability; or neither headache nor neck pain. Pain pressure threshold, allodynia, muscle strength, and endurance and cervical muscles activity were evaluated.
    Results: One hundred subjects, with mean age of 30.4 years old, were stratified by diagnosis (n = 25 per group) and by self-reported pain during tests. Lower endurance during flexion was observed for migraine and neck pain (34s) relative to neck pain alone (45s), migraine (40s), and controls (58s) (p = 0.04). For extensor endurance, means were 142s, 166s, 215s, and 270s, respectively (p < 0.001). Endurance times were impacted by the presence of test-induced pain decreasing about 40%-53% of the performance. Diagnostic groups did not differ significantly in strength (p > 0.05), but all pain groups presented significantly higher proportion of test-induced pain, lower muscle activity during the maximal isometric voluntary contractions, and lower pressure pain thresholds.
    Conclusion: Patients with migraine, chronic neck pain, and the association of both present altered cervical muscle function and activity. Also, test-induced pain impacts significantly on neck muscles endurance.
    Significance: The diagnosis of migraine and chronic neck pain is associated with altered function and activity of the cervical muscles. However, the test-induced pain had an important contribution to worse cervical muscle endurance. This suggests that the therapeutic approach should focus on de-sensitization of the trigeminal-cervical complex when dealing with the comorbidity of migraine and cervical pain.

    Abstract Sharks, as apex predators, play an essential ecological role in shaping the marine food web and maintaining healthy and balanced marine ecosystems. Sharks are sensitive to environmental changes and anthropogenic pressure and demonstrate a clear and rapid response. This designates them a "keystone" or "sentinel" group that may describe the structure and function of the ecosystem. As a meta-organism, sharks offer selective niches (organs) for microorganisms that can provide benefits for their hosts. However, changes in the microbiota (due to physiological or environmental changes) can turn the symbiosis into a dysbiosis and may affect the physiology, immunity and ecology of the host. Although the importance of sharks within the ecosystem is well known, relatively few studies have focused on the microbiome aspect, especially with long-term sampling. Our study was conducted at a site of coastal development in Israel where a mixed-species shark aggregation (November-May) is observed. The aggregation includes two shark species, the dusky (

    Abstract Introduction: Kinesiophobia is a common symptom associated with high disability, and has been observed in patients with migraine. However, the association between kinesiophobia and clinical factors in this population is unknown.
    Objective: To assess the fear of falling, dizziness disability, and migraine disability in patients with migraine, considering the presence of kinesiophobia.
    Methods: Eighty patients with migraine completed the Tampa Scale for Kinesiophobia and were divided into two groups according to the questionnaire cutoff point: migraine without kinesiophobia (MoK, n = 39) and migraine with kinesiophobia (MK, n = 41). Fear of falling, dizziness disability, and migraine disability were assessed in both groups using validated questionnaires.
    Results: The MK group presented higher scores on dizziness disability, fear of falling, and migraine disability compared to the MoK (
    Conclusion: The presence of kinesiophobia should be considered in clinical practice when evaluating migraine, as it is associated with increased levels of fear of falling, dizziness disability, and migraine disability.

    Abstract Objectives: To assess the prevalence of specific headache disorders in a population older than 65 years seeking consultation due to memory problems or cognitive impairment.
    Methods: We verified the occurrence of headache symptoms and the impact of headaches on daily life. Headaches were classified as per the International Classification of Headache Disorders, 2nd edition (ICHD-2). All patients were screened with the Mini-Mental State Examination (MMSE), followed by the Selective Reminding Test and neuroimaging. Participants with severe cognitive impairment or dementia were excluded.
    Results: A total of 1,237 patients (51.6% women), with mean age of 75.6 years (SD = 6.9) were screened from January 2006 to December 2014. Of them, 302 (24.4%) patients suffered from headaches. Most common individual diagnoses were probable migraine (13.8%), episodic tension-type headache (3.4%), and episodic migraine (3.0%). Chronic migraine or probable chronic migraine happened in 3.5%, while chronic tension-type headache affected 0.6%. Most patients with headaches routinely used symptomatic medications (55.6%). Mean MMSE scores were similar in patients with or without headaches, or with different headache diagnoses.
    Conclusions: Headache disorders overall, frequent headaches, and headaches requiring treatment are commonly seen in the elderly seeking care for cognitive decline and should be properly assessed and managed.

    Abstract CGRP is an extensively studied neuropeptide that has been implicated in the pathophysiology of migraine. While a number of small molecule antagonists against the CGRP receptor have demonstrated that targeting this pathway is a valid and effective way of treating migraine, off-target hepatoxicity and formulation issues have hampered the development for regulatory approval of any therapeutic in this class. The development of monoclonal antibodies to CGRP or its receptor as therapeutic agents has allowed this pathway to be re-investigated. Herein we review why CGRP is an ideal target for the prevention of migraine and describe four monoclonal antibodies against either CGRP or its receptor that are in clinical development for the treatment of both episodic and chronic migraine. We describe what has been publically disclosed about their clinical trials and future clinical development plans.

    Abstract Calcitonin gene-related peptide (CGRP) is a neuropeptide of importance in migraine pathogenesis. Its central role in migraine was proven pharmacologically by the development of CGRP receptor antagonists. Monoclonal antibodies targeting CGRP or its receptor are effective in the preventive treatment of episodic and chronic migraine and are considered potential breakthroughs in their treatment. Fremanezumab (previously known as TEV-48125, LBR-101, or RN-307) is a humanized IgG2a monoclonal antibody that binds to CGRP. The development of this antibody validated the role of CGRP in chronic migraine and the drug has been recently approved in the US by the FDA, while it continues to be reviewed by other regulatory agencies. Herein we provide an in-depth review of its development. We start by summarizing its in vitro and in vivo pharmacology, and the phase I studies. We then review the late-stage clinical development, with a focus on its efficacy, safety, similarities, and uniqueness relative to other CGRP antibodies. We close by discussing lessons learned on the mechanisms of migraine and areas for future development and exploration.
