[Indicators of stroke morbidity and mortality from stroke in the territories included in the Federal program of caring for patients with stroke]

OBJECTIVE

To study and analyze the dynamics of stroke morbidity and mortality rates among men and women in the territories included in the Federal program for the reorganization of care for stroke patients.

MATERIAL AND METHODS

The study was based on data from the territorial-population register of strokes. The study included the following territories: Ivanovo region, Stavropol territory, the Republic of Bashkortostan, Sverdlovsk region, Irkutsk region, Sakhalin region, and the Republic of Tatarstan. Research period was from 2009 to 2016. A total of 29 779 stroke cases were analyzed. The age of the examined people was 25 years and older.

RESULTS AND CONCLUSION

In the study areas, a 2.2 - fold decrease in stroke mortality among men and a 3-fold decrease among women was found. The values of morbidity and mortality from stroke over the entire study period were higher among men. It was also revealed that in 2015-2016, the mortality rate was in a narrow range of values, which demonstrates the impact of comprehensive measures to reduce stroke mortality in all the studied territories. The results of cluster analysis of stroke incidence rates obtained from seven territories over an 8-year period indicate similar measures for primary stroke prevention among men. Among women, there are also similarities in primary stroke prevention measures, with the exception of two regions - the Stavropol territory (4.8 cases per 1000 population) and the Republic of Tatarstan (4.5 cases per 1000 population), where the highest values of the stroke incidence rate were found. The results of cluster analysis of stroke mortality rates among men indicate a fairly large variation in the indicator values. The dominant value of the stroke mortality rate among men was found in the Sakhalin region (1.61 per 1000 population). The significance of stroke mortality rates among women in the regions was similar: six territories with similar levels of values were identified. The exception was the Stavropol territory (2.48 cases per 1000 population), where the highest death rate from stroke was revealed.

Diagnosis and treatment of migraine: Russian experts' recommendations

Migraine is one of the most common types of headache, which can lead to a significant decrease in quality of life. Researchers identify migraine with aura, migraine without aura, and chronic migraine that substantially reduces the ability of patients to work and is frequently concurrent with mental disorders and drug-induced headache. The complications of migraine include status migrainosus, persistent aura without infarction, migrainous infarction (stroke), and a migraine aura-induced seizure. The diagnosis of migraine is based on complaints, past medical history, objective examination data, and the diagnostic criteria as laid down in the International Classification of Headache Disorders, 3 rd edition. Add-on trials are recommended only in the presence of red flags, such as the symptoms warning about the secondary nature of headache. Migraine treatment is aimed at reducing the frequency and intensity of attacks and the amount of analgesics taken. It includes three main approaches: behavioral therapy, seizure relief therapy, and preventive therapy. Behavioral therapy focuses on lifestyle modification. Nonsteroidal anti-inflammatory drugs, simple and combined analgesics, triptans, and antiemetic drugs for severe nausea or vomiting are recommended for seizure relief. Preventive therapy which includes antidepressants, anticonvulsants, beta-blockers, angiotensin II receptor antagonists, botulinum toxin type A-hemagglutinin complex and monoclonal antibodies to calcitonin gene-related peptide or its receptors, is indicated for frequent or severe migraine attacks and for chronic migraine. Pharmacotherapy is recommended to be combined with non-drug methods that involves cognitive behavioral therapy; progressive muscle relaxation; mindfulness; biofeedback; post-isometric relaxation; acupuncture; therapeutic exercises; greater occipital nerve block; non-invasive high-frequency repetitive transcranial magnetic stimulation; external stimulation of first trigeminal branch; and electrical stimulation of the occipital nerves (neurostimulation).
