    Migraine and neck pain: Mechanisms of comorbidity

    Get PDF
    Neck pain and migraine are common diseases. Neck pain seldom occurs in a patient with migraine. However, the relationship between migraineΒ and neck pain has been inadequately investigated.Objective: to analyze neck pain in patients with migraine to determine possible comorbidity mechanisms of these diseases.Patients and methods. The investigation enrolled 63 patients with chronic migraine (CM) and 40 with episodic migraine (EM) diagnosed inΒ accordance with the International Classification of Headache Disorders, 3rd edition (ICHD-3). Winking reflex (WR) and nociceptive flexionΒ reflex (NFR) were examined to evaluate the function of antinociceptive systems.Results. In the patients with CM, neck pain was more common than in those with EM (53.03% versus 14.02%); and panful tenderness, sensitivity,Β and tension of neck muscles were more marked. There was also a significant reduction in WR and NFR thresholds. Neck pain was notedΒ to be an integral component of the pathogenesis of CM in a large number of patients with this condition. The authors proposed several pathophysiologicalΒ mechanisms of a relationship between migraine and neck pain. Neck muscles and craniovertebral junction areas serve as a sourceΒ for the arrival of nociceptive pain pulses in the central nervous system (peripheral sensitization), promoting pain chronization. Muscle dysfunctionΒ in this area may be, in turn, a reflection of central sensitization and impaired descending pain control

    Depression is not the only cause of cognitive impairment in chronic migraine

    Background.Β Patients with the chronic migraine frequently present with memory and attention complaints. However, the prevalence and phenotype of such impairment in chronic migraine have not been studied.Objective – to evaluate the prevalence of the objective cognitive deficit in patients with chronic migraine and factors underlying its etiology.Β Materials and methods.Β We recruited 62 subjects with chronic migraine and 36 genderand age-matched controls with low-frequency episodic migraine (not more, then 4 headache days per month) aged 18–59. All patients filled in the Hospital Anxiety and Depression Scale (HADS) and Sheehan Disability Scale. Cognitive function was assessed with the Montreal Cognitive Assessment (MoCA), Digital Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT), and the Perceived Deficits Questionnaire (PDQ-20).Results.Β In this study 58 % of patients with chronic migraine complained of memory loss. Cognitive impairment was also found with PDQ-20. Objectively, we found a significant decrease in 90-second DSST results and RAVLT total recall and learning rate. In 40 % of subjects with chronic migraine scored lower than 26 points on MoCA. Patients with chronic migraine more frequently had lower DSST rates as compared to episodic migraine (odds ratio 5.07 (95 % confidence interval – 1.59–16.17); p = 0.003). Depression and anxiety did not correlate with performance on cognitive tests. Chronic migraine (frequent headache) and longer headache history, but not depression, anxiety or medication overuse were independent predictors of cognitive impairment.Conclusion. Subjective and objective cognitive deficits are prevalent in the chronic migraine population. Most often memory and attention are impaired. Longer headache history and presence of chronic migraine are independent risk factors for cognitive impairment in patients with chronic migraine

    Molecular Principles of Gene Fusion Mediated Rewiring of Protein Interaction Networks in Cancer

    Get PDF
    Gene fusions are common cancer-causing mutations, but the molecular principles by which fusion protein products affect interaction networks and cause disease are not well understood. Here, we perform an integrative analysis of the structural, interactomic, and regulatory properties of thousands of putative fusion proteins. We demonstrate that genes that form fusions (i.e., parent genes) tend to be highly connected hub genes, whose protein products are enriched in structured and disordered interaction-mediating features. Fusion often results in the loss of these parental features and the depletion of regulatory sites such as post-translational modifications. Fusion products disproportionately connect proteins that did not previously interact in the protein interaction network. In this manner, fusion products can escape cellular regulation and constitutively rewire protein interaction networks. We suggest that the deregulation of central, interaction-prone proteins may represent a widespread mechanism by which fusion proteins alter the topology of cellular signaling pathways and promote cancer

    Current status of the temperature and humidity regime of the troposphere in the Siberian sector in different circulation periods

    Get PDF
    The paper studies the long-term dynamics of air temperature and relative humidity anomaly indices in the surface layer and at different levels of the troposphere in Siberia and neighboring regions (European and Far Eastern sectors). As the main cause of the observed variations in climatic parameters we considered circulation factors, which were taken into account using the typification of macrocirculation processes proposed by B.L. Dzerdzeevsky. Seasonal differences were revealed in the distribution of anomaly indices and the area occupied by anomalies of different signs of annual and monthly mean temperature and relative air humidity, which are most pronounced during circulation periods of increased duration of meridional northern processes in the Siberian sector and in the Northern Hemisphere as a whole. The highest rates of change in the temperature regime in the Siberian sector over recent decades have been observed at the level of the isobaric surface AT–700 hPa (3 km), which affects the advective-dynamic factors of surface cyclo- and frontogenesis, as well as the processes of cloud formation and precipitation. In general, an increase in the heat content of the lower and middle troposphere and a decrease in the relative moisture content near the tropopause can be accompanied by an increase in the amount of the potential energy and convective instability energy reserves and can lead to an increase in climate risks in the Siberian sector

    Background.Β Memory and attention deficits are prevalent in the chronic pain population. There are multiple common mechanisms in chronic pain and cognitive impairment. However, the presence, prevalence and clinical burden of such impairment are frequently underestimated.Objective:Β to evaluate subjective and objective cognitive deficits in patients with chronic migraine (CM).Materials and methods.Β We recruited 53 subjects with CM and 22 genderand age-matched controls with low-frequency episodic migraine (a maximum of 4 headache days per month) aged 18–59. All patients filled in the HADS (Hospital Anxiety and Depression Scale) anxiety and depression scale and Pittsburg Sleep Quality Inventory (PSQI). Cognitive function was assessed with Montreal Cognitive Assessment (MoCA), Digital Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT) and the Perceived Deficits Questionnaire (PDQ-20).Results.Β 56 % of patients with CM complained of memory problems. Decreased cognitive function was also observed during self-assessment using the PDQ-20 questionnaire. Objectively, we found a significant decrease in 90-second DSST results and RAVLT total recall and learning rates. 44 % of subjects with CM scored lower than 26 points on MoCA. Most frequently we found impairments in attention (75 %), memory/delayed recall (50 %), language (50 %) and executive function (37 %). Depression and sleep quality correlated with only several parameters of cognitive tests.Conclusion.Β Subjective and objective cognitive deficits are prevalent in the CM population. Most often memory and attention are impaired. Cognitive complaints need to be carefully assessed, and treatment of such impairment may improve quality of life and decrease disability in CM.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.Β ΠΠ°Ρ€ΡƒΡˆΠ΅Π½ΠΈΡ памяти ΠΈ внимания ΡˆΠΈΡ€ΠΎΠΊΠΎ распространСны Ρƒ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с хроничСской болью.

    Over a half of chronic pain (CP) patients present with cognitive complaints, which increase their disability and impact quality of life. The paper reviews objective impairments in memory, attention, processing speed and executive function demonstrated in the CP population. The paper also reviews common pathology underlying cognitive impairment and CP: neuroplasticity in the shared brain areas, neurotransmitter and other molecular mechanisms.
